—Kraid, Super Smash Bros. Ultimate

Kraid (クレイド Kureido?) is a corpulent, three-eyed green reptilian extraterrestrial from the Metroid series. He is one of the largest enemies Samus ever encounters in her missions, taking up multiple screens at a time. He is featured in Metroid, its remake Metroid: Zero Mission, Super Metroid, and Metroid Dread.

Kraid is a Space Pirate, and though his rank within the marauding race has never been officially stated, he is likely a high-ranked member and may even be a leader, as he is a prominent boss in his canon appearances. Notably, he is part of the original game's boss duo, the other being his comrade Ridley.

Additionally, Kraid is described in the Metroid Prime manual alongside Ridley as the Space Pirate armies' "mainstays"; one could easily imagine this colossus as the muscle and backbone behind Pirate attacks and raids. As is the case with the Pirates stationed on Zebes, Kraid is not a native of the planet and his origins, along with his homeworld, remain unknown. Both of Samus Aran's missions on Zebes require Kraid to be killed, among others, as a means to infiltrate the Pirate HQ, Tourian.

A press kit profile for Super Metroid has Samus refer to Kraid as the "brutal ruler of Brinstar". In official Zero Mission art on the Japanese website, Kraid is titled the Awakened Behemoth (目覚めた巨獣生物?).


Kraid attacks solely with his body's natural weapons. He shoots dagger-like spikes from his belly and spinning claws from his hands, the latter which consist of either his nails or fingers; all of his weapons are infinitely generated in his body. In his Super Metroid and Metroid Dread appearances, he gains the ability to spew out rock-like projectiles from his mouth in addition to small fireballs in the latter game. Kraid also uses his arms' raw strength to hit Samus while using his massive body to push and corner her.

In Super Metroid, Kraid is seen tunneling out of the ground prior to his battle, establishing him as a natural digger. He also tunnels out in Metroid: Zero Mission but to a far lesser extent.

In Metroid Dread, Kraid is shown to be resistant to lava since he is capable of moving through the substance within the range allowed by his restraints while his feet and tail are submerged. Though this resistance is not limitless as he proceeds to sink and seemingly drown in the lava when his restraints, which were keeping him afloat, are removed. While not nearly to the extent of his comrade Ridley, he does show some degree of intelligence; when he notices that his right arm shackle breaks off, he immediately takes the opportunity to smash the platform Samus was on, and later uses his unshackled arm to swat Samus off the blue magnetic strip that allows her to fire at him. He is noticeably very short-tempered, much to his own detriment, such as roaring repeatedly at Samus in anger when he is shot in the face despite this very response leaving his mouth vulnerable to damage.



The 8-bit Kraid, as shown in Metroid.

In the Famicom and NES version of Metroid, Kraid is the boss of Mini-Boss Hideout I. He is found in a room containing a large platform surrounded by a pool of acid. His original design differed considerably from that of later installments. Kraid's artwork seems to show that, in addition to being approximately the same height as Samus, he also appears to have green fur on his back and only two eyes. There are also spikes located on his back that are shot out and diverge towards the front, similar to boomerangs, in an arching trajectory. The three spikes on his belly and face are always launched in a straight path. The entire boss battle consists of Kraid walking back and forth on his platform as he constantly hurls his weapons at Samus.

All of Kraid's projectiles also serve a defensive tactic; due to their invulnerability, they can destroy all of Samus' long-range weapons on contact. In particular, the middle spike on Kraid's front is aligned with her Arm Cannon's line of fire, requiring either precise jumps to shoot in-between the top spikes, or strict timing in order to shoot his vulnerable body before his spikes reform on him. Samus can, however, use the Ice Beam to temporarily freeze Kraid's spikes in midair and away from him, leaving him completely exposed and unable to generate additional spikes until the ice thaws. Only the front spike closest to the floor can never be frozen because of the absence of crouching or diagonal aim in the game. One must be careful with the Ice Beam, for if Kraid's projectiles freeze before he launches them, they'll remain attached to his body for an extended period, somewhat increasing his defenses and thus further hinder Samus. Her Screw Attack and Bombs can also harm him, but the close proximity needed to make them effective will put her health at great risk. Due to all of the mechanics implicated in Kraid's battle, he is generally considered to be a more difficult boss than Ridley.

His defeat triggers one of the Stone Statues and increases Samus' Missile ammo capacity by 75.

There is also a Fake Kraid which Samus can encounter before fighting the real Kraid. However, since there are multiple paths leading to the authentic Kraid, Samus may never come across the imposter. Fake-Kraid shares the same attacks and the appearance of his namesake, but it is a darker shade of brown with light blue fur and is rather feeble by comparison. Unlike the real Kraid, it respawns even if killed by simply re-entering the decoy's room. Worthy to note is that due to the Famicom console's superior internal memory, the back spikes on Kraid and his doppelganger are thrown in various different trajectories chosen at random, while the NES console's lower specs only offer a single path for these projectiles (among other objects and enemies in-game), making the American version of Metroid slightly less challenging.

Metroid: Zero Mission[]

The Kraid as shown in Metroid: Zero Mission.

In the remake of the first Metroid game, Kraid's size and appearance are revised to being similar to his appearance in Super Metroid. Kraid's hideout is now named after him and remains separate from Brinstar, unlike Super Metroid where his lair was simply a section of the latter. His weaker decoy is nowhere to be seen.

Kraid is initially asleep with the lower half of his body partially buried when Samus first enters his room. He immediately wakes up and emerges fully out of ground to initiate the battle. He will hurl from his right hand destructible, spinning claws (similar to his chronologically subsequent appearance in Super Metroid) while periodically swiping at Samus with his left arm. In the remake, his entire body is invulnerable save for the inside of his mouth, which can be exposed by shooting a charged beam or any concussive weapon at his eyes. Once Kraid has taken enough damage with any of these, or if Samus is to fall off the pillar she is standing on, he will begin to continously shoot his two lowest belly spikes at her; this destroys most of the pillar in the process, leaving only a tiny block to stand on. Regardless of whether the spikes hit Samus or not, they will stick onto the back wall, allowing her to use them as platforms to reposition herself in front of Kraid's head if she were to fall, but only briefly as they explode within seconds. When Kraid's health is further reduced, he will begin shooting spikes from all three belly holes, crumbling the final remnants of the stone pillar. When Kraid is defeated, he partially sinks to the floor and vanishes in a large explosion, unlocking one of the Stone Statues' gates.

His battle theme in Zero Mission is a remix of the boss theme in Super Metroid, which was also used with Crocomire, Phantoon and the Big Metroid.

Metroid: Volume 2[]

Kraid appears in the second half of the Metroid: Volume 2 manga, which is an adaptation of most of the events of Zero Mission. Mother Brain describes Kraid as being "Ridley's comrade" and also states that "his skin is on par with an anti-optical shield", explaining how most weapons cause him very little damage.

Metroid Prime[]

The Metroid Prime game's instruction manual makes reference to events which occurred in the original Metroid, such as Samus Aran killing the "gargantuan mainstays of the Space Pirate army, Ridley and Kraid", foreshadowing their retconned sizes in Metroid: Zero Mission. The manual also mentions that, after the fall of Zebes's Pirate base, the Space Pirates orbiting the planet split into two main camps - one to search for a planet with powerful energy resources (soon settling on Tallon IV), and the other to rebuild their ravaged facility on Zebes and begin resuscitating Ridley, Mother Brain, and Kraid. Only Ridley, as the reborn Meta Ridley, would make an active appearance in the game, with the other two's redevelopment at an unknown status throughout the entire Prime series.

Super Metroid[]

The 16-bit Kraid as shown in Super Metroid.

Kraid reappears in Super Metroid in his large form. He takes up approximately two vertical screens' worth of space, making him the largest being in the entire game. Kraid only receives damage when he is shot in the mouth, and he exposes this weakpoint in frustration after being hit in the eyes with a Missile, Super Missile, or beam shot (charged or uncharged). Four Super Missiles or 20 missiles/charged shots in total are necessary to defeat Kraid.

As Samus enters his room and stands on the only platform available, Kraid is nowhere to be seen initially, until he tunnels out of the organic thorns covering the entire floor in front of the heroine. Due to the room's low ceiling, only Kraid's upper torso rises aboveground. During this phase, Kraid's attacks consist only of hurling rock-like projectiles from within his mouth (four in a row), and a ram in which he attempts to skewer Samus against the wall with his fingers. Because of the small platform and low ceiling, Samus has limited space to manage his attacks. After a set amount of damage is inflicted on him, Kraid will rise entirely out of the ground, breaking the ceiling above in the process, revealing a far larger room with platforms standing above the thorn-covered ground.

At this point, Kraid will cease to use his rock-like projectiles and instead shoot spikes from all three belly holes, as well as throwing his fingers around the room. These attacks have different properties from their "past" Zero Mission variant: the fingers now bounce off any flat surface they collide with rather than exploding on contact, thus they remain on the field for a far longer amount of time and can reach Samus from multiple directions. As for the belly spikes, they are not only launched out at a much faster rate, they no longer jab onto the wall behind Samus and instead pierce completely through it, giving her substantially less time to use them as platforms. Kraid's mobility is significantly quicker; as he moves back and forth across the room, he can potentially push Samus off the small platforms and into the hazardous ground below, or damage her by colliding his fingers onto her, or a combination of both. As he dies, the floor will seemingly crumble beneath Kraid and he will fall through it while weakly roaring. His death will deactivate one of the Golden Statues.

Akin to the original Metroid game, there is an imposter appropriately named Mini-Kraid. He is encountered two rooms prior to Kraid's; it is dwarf-like in comparison, both in terms of size and strength. Similarly to the Metroid decoy, it respawns after it is destroyed if Samus re-enters its corridor. Numerous Green Space Pirates and Kihunters patrol the rooms before the boss' chamber, seemingly to defend Kraid and Mini-Kraid.

Just outside Kraid's room, there is a mysterious dead body with signs of advanced decomposition. It is unknown if the killer was Kraid or his respective Gadora.

Metroid Dread[]

Samus confronting Kraid in Metroid Dread.

After decades of absence from the series, Kraid returns in Metroid Dread as the second boss in Cataris. Although the Chozo Archives depict Raven Beak's Mawkin Chozo Soldiers restraining him in Cataris, no further explanation is given for his return. While identified as Kraid in the game's map and Mission Log, it is unclear if this is the same character from previous games; Metroid Dread Report Volume 6 coyly describes the boss as "a giant monster who appears to be Kraid" rather than outright confirming his identity, and Quiet Robe's exposition presents an unclear timeline for the aforementioned Chozo Archives image since all Mawkin soldiers were infected by X Parasites and quarantined in Elun while Samus exterminated the Metroids on SR388. This could suggest that this Kraid may be a separate specimen (much like Mini-Kraid) captured at an earlier time by the Mawkin tribe. Otherwise, this would mean that the Chozo Soldiers had not yet been fully infected by the X during the events of Super Metroid; a fresco in Ferenia indicates that the Mawkin had some history with Mother Brain and the Zebesians, which may tie into their acquisition of Kraid.

Kraid was first revealed to be returning in Dread during the second trailer, where he is shown confronting Samus. Volume 6 of the Metroid Dread Report describes him as "a giant monster that appears to be Kraid, a beast Samus has fought in previous games". The Metroid Dread - Overview Trailer and the Find Your Power commercial showed further glimpses of Kraid's battle with Samus.

Kraid is found in a large room full of lava, bound by restraints around his neck and wrists. His roars can be heard from neighboring rooms as Samus approaches his location. Upon entering his room, Samus remains cautious but eases up upon seeing the restrained Kraid as he furiously roars and lunges at her, calmly shooting him in his open mouth with her Charge Beam.

Upon Kraid's defeat, Samus runs up his belly, dodging a swipe from his newly-freed right arm and an attempt to catch her in his jaws before leaping over his head to stand on the moorings for his neck restraint. When Kraid turns to face her, she shoots him in order to provoke a swipe from him that severs one of the cables holding his collar. This causes Kraid to begin sinking into the lava, revealing that the wired shackles had a dual purpose: keeping him prisoner and maintaining his body afloat. He grabs the surrounding walls to stop his descent and manages to fire one last stomach spike that Samus dodges with ease before the final cable, unable to support the massive beast's weight, breaks off. Without the cables' assistance, Kraid loses his grip and with the large shackle around his neck likely weighting him further down, he starts thrashing in the lava in a panic. He momentarily holds onto the ledge of where Samus is standing, then slowly disappears beneath the hazardous substance. Afterwards, Samus uses Kraid's final spike as a platform to reach the door out of the room leading her to obtain the Diffusion Beam.

Overall, Kraid's viciously aggressive reactions throughout this entire encounter imply he is the same individual from previous battles and he recognizes his old foe Samus. Alternatively if this specific beast is merely another member of Kraid's species, his aggression may be a Pavlovian response to seeing her wearing Chozo armor, associating Samus with his captors.

Although Kraid's fate after his defeat is never explicitly shown, it is heavily implied that he was either consumed by a purple X Parasite following their release from Elun, or at the very least the X replicated his DNA via the spike he ejected earlier; when Raven Beak is absorbed by the purple X at the end of the game, he transforms into Raven Beak X, a giant amalgamated monstrosity which includes prominent features from Kraid.[1] Since the creature and its parasite were subsequently obliterated by Samus's Hyper Beam and the entirety of ZDR self-destructed minutes later, it can be safely assumed that Kraid, if he is the same Space Pirate encountered in the past, has truly met his end.

An unique theme plays during the battle with Kraid, internally titled Boss Kraid. This theme does not closely resemble Big Boss Confrontation from Super Metroid and Zero Mission, instead using the melody from the main theme of Cataris.


Samus firing into Kraid's mouth.

As usual, Kraid's weak point is his mouth, which he opens in some animations or if Samus shoots him in the eyes with Charge Beam or Missiles. After making some attempts to free himself from his restraints (leaving his mouth open for attack in the process), he attacks by firing globules from his mouth, with his throat enlarged in a similar manner to a toad (or Corpius). Samus can destroy the globules for pickups, but she must dodge the fireballs Kraid occasionally spits out along with them. Kraid also launches his fingernails as projectiles, which can be destroyed or evaded; just like in Zero Mission, his nails are shown growing back from his fingers after being fired off.

Once Kraid takes sufficient damage, he frees his left arm and smashes the platform Samus was standing on, forcing her to stand on the damaged platform on the surface of the lava. He attempts to advance further towards Samus, but his remaining restraints stop him from getting any closer, causing him to roar at Samus in irritation. Here, he attacks with projectiles fired from his stomach holes, including Kraid Bouncing Creatures, which can be destroyed for Energy or Missiles; blobs of pink goo, which land in the center of the platform and splash across the floor; and his classic giant spikes, which impact the left wall and briefly linger before shattering. Samus can attack the purple-glowing middle stomach hole to make Kraid flinch; she can gauge her progress by the glow that spreads along the cracks surrounding it.

After flinching, Kraid will release spikes from all three of his stomach holes, which Samus should duck under as they smash into the wall. The tremor brings down a blue magnetic strip that Samus can cling to with the Spider Magnet; after a moment, it rises to the point where she can shoot Kraid's head again. An alternative means to reach Kraid's head is to wait for his regular spike attack; before they shatter, Samus can use them as platforms to reach the blue magnetic strip.

No matter how Samus gets to the magnetic strip, she has to resume her previous tactic of shooting Kraid in the mouth (usually by shooting his eyes first). Kraid will retaliate with his fingernail projectiles and a backhand swipe from his left arm; the latter can be blocked with the Melee Counter, allowing Samus to initiate a Grab Sequence by shooting Kraid while he is stunned. After a few attacks, he will wind up a punch with his left arm to try and force her off of the strip; he will telegraph this move by roaring twice as his eyes glow brightly. With good timing, Samus can jump over Kraid's fist and grab onto the strip as she comes back down.

If Samus lets go of the strip by either jumping off or being hit, she will land on the lower level and have to repeat Kraid's second phase to reach his head once more. However, if Samus used Kraid's spikes to reach the magnetic strip, the middle stomach hole will retain whatever damage she inflicted if she comes back down; this can shorten the time it will take for her to make Kraid flinch.

If Morph Ball Bombs have been obtained via sequence breaking, Samus can use the Morph Ball launcher hidden in the lower left corner of the room to blast herself into Kraid's middle stomach hole; from there, she can repeatedly plant Bombs inside it to quickly defeat Kraid. This must be done quickly, as Samus will take steady damage while she is inside the hole. If Flash Shift is obtained, Samus can instantly trigger the Grab Sequence by Flash Shifting to his face when he tries to lunge at her and his eyes flash.[2]

Cancelled appearances[]

"What's the matter? All I said was that Komaytos look like little Metr-"

Non-canon warning: This article or section contains information that may not be considered an official part of the Metroid series in the overall storyline by Nintendo.

Metroid Prime[]

Kraid as he would have appeared in Prime.

Kraid was intended to have a larger role in the first Metroid Prime game; a reborn Kraid was planned to make an appearance as a boss character in the Phazon Mines area on Tallon IV. He was modeled and textured by Gene Kohler for that purpose. He possessed what appears to be a metal helmet on his head, likely made by the Space Pirates to protect his eyes (an exploitable weakpoint established in other games). Kohler indicated in an email reply to N-Sider that the helmet was supposed to be an obstacle to be overcome in the planned fight against him. This was later clarified by an anonymous former employee at Retro who stated players needed to cause objects to collapse onto his armored head, a goal made difficult by Kraid firing projectiles at Samus from his belly holes and tipping over the platforms she needed to ascend; the former employee further stated there may have been additional phases to the fight, but could not recall them. Interesting to note is that his belly projectiles were mentioned by the same person to be missiles instead of the organic spikes previously used on Zebes, strongly implying that the Space Pirates had installed weapon systems in his body. While Kraid likely was not cybernetically enhanced to the same extent as his comrade Meta Ridley, the missile system and the metal helmet contribute the fan-coined nickname "Meta Kraid".

A piece of concept art made during Metroid Prime's development shows a helmetless Kraid extending multiple organic spears from his stomach at Samus while she is jumping and firing at his exposed face; she appears to have simultaneously destroyed some of his uppermost spears and dodged a strike from his left hand along the way. This concept, in which Kraid features over two dozen belly ports launching a different type of weapon, may have represented a phase following the destruction of his helmet. The fight (and character) ultimately did not make its way into the game in time for the release. According to Jack Mathews, the Omega Pirate replaced Kraid, since it was built on the existing Elite Pirate AI, whereas Kraid required new AI to be written.[3]

Due to being cut from Metroid Prime, Kraid's only 3D appearances had been in other series, namely the Planet Zebes: Brinstar Depths stage of Super Smash Bros. and the Metroid Blast attraction of Nintendo Land, until he finally appeared 19 years later in Metroid Dread.

Developer comments[]

I had completely finished modeling and texturing Kraid. The level that he was to be included in was well underway to being designed. There just was not enough development time remaining to fully implement all aspects of the scenario that were needed to pull off a highly polished\fun gaming experience... animations\effects\programming\etc. It was decided that Kraid was not imperative enough to the Metroid Prime project to run the risk of pushing up the release date in order to fit him in.

I'm sure the folks over at Retro are designing ways to fit Kraid in possible future Metroid titles.

—Gene Kohler, May 11, 2004 (

According to Mr. Kohler in an email to N-Sider, Kraid is said to have a metal plate covering his face due to it being a designed gameplay feature - an item that you had to overcome in your encounter against Kraid. Although, he said, if the model does appear in a future Metroid title, expect some modifications to be made as the older ideas become refined.


Kraid was really just some ideas and a first pass model. We were about to start work on him when he was cut. The overall idea was to have Kraid at one end of a large cavern, and some rickety platforms at the other end that Kraid could reach out to and tip over. He would also fire missiles at you from his belly ports. As I recall you would have to climb to the top and trigger something to collapse on him several times. There were probably other stages but I don’t remember them.

—Anonymous Retro Studios Employee[4]

Probably the biggest throwaway I remember was Kraid. There were some prototypes for him, but it was pretty obvious we would run out of time to get him done.

(asked to elaborate) I wish I remembered more. I just remember he was huge, that there were a bunch of jumping pieces, and that there was no way we were going to make it work in the time we had. I believe the Omega Pirate took his place, and I’m actually ok with that, because I thought that ended up being a pretty cool boss.

Jack Mathews, January 20, 2018[5]

Mathews also joked that Kraid was cut because "we had a hard time finding him a toothbrush".[6]

Metroid Prime 3: Corruption[]

Though Kraid does not appear in this game, a released storyboard for an unused introduction animation by Ben Sprout features a creature resembling Kraid attacking Samus, but is quickly destroyed by her Gunship. This design features an additional row of spikes placed horizontally across his chest, with vertical rows of upward facing spikes seen at the creature's sides. Finally, each of his arms end in a single, largely extended claw-tipped appendage.

Appearances in other media[]

Metroid: Zebes Invasion Order[]

"Kraid, the boss of area A, began his attack as soon as he appeared, without stopping for a breath."

Just as in Metroid, Metroid: Zero Mission, and Super Metroid, Kraid appears as a guardian of the Space Pirate stronghold on planet Zebes. Normal beam attacks do not work on Kraid; missiles must be used to damage him. He resides in Brinstar room A-22, which is guarded by a Side Hopper and a Doublehopper. Upon his demise, Kraid explodes in a bright flash and drops a Key Stone, which is used to activate his Stone Statue.

Captain N: The Game Master[]

In the animated cartoon series Captain N: The Game Master, Kraid appears as a minor recurring character in multiple episodes, acting as a minion who serves Mother Brain. He is frequently seen patrolling Metroid as a guard, armed with a spear-like weapon and a Missile Gun holstered on his belt.

As with many other characters in the series, Kraid has a drastically different appearance from his canonical design, resembling an overweight bipedal rhinocerus wearing a green tunic and blue hat. Since Kraid is never identified by name in the show itself, his identity has only been confirmed by concept artwork of Kraid's Missile Gun.

In Kevin in Videoland, Kraid makes a cameo appearance as the minion guarding Princess Lana's prison cell. He is instantly defeated when Kevin lands on him, in a similar manner to Super Mario Bros. enemies.

In Mega Trouble For Megaland, Kraid is seen enslaving the residents of Mt. Icarus, which has been renamed Mt. Mother Brain after being conquered by the Forces of Chaos. He appears alongside an identical creature, which may be a possible reference to Fake Kraid. Notably, this episode is the only time Kraid has been voiced with dialogue, speaking with a high-pitched scratchy voice as he threatens the enslaved workers. While his voice actor has never been confirmed, several unofficial websites credit Doug Parker (who also voices Mega Man in the same cartoon) with voicing Kraid.[citation needed][7][8]

In Metroid Sweet Metroid, Kraid and a Viola patroll Metroid while Kevin and Duke are trapped in its corridors. Later, Kraid finds Duke lying on the floor and prods at him with his spear-like weapon, unaware that Duke is merely playing dead as a distraction. Kevin sneaks up on Kraid and ties him up with rope, then steals his Missile Gun.

In Gameboy, Kraid is among the monsters generated by the Mother Brain-controlled Gameboy. He charges at Simon Belmont and pins him against a wall. Once Duke unplugs Gameboy, Kraid vanishes along with all of the other monsters.

Nintendo Comics System[]

Kraid appears as a character in the Nintendo Comics System adaptations of Metroid and Captain N. Unlike his animated appearance, Kraid much more closely resembles his original artwork from Metroid.

In The Coming of a Hero, Kraid and Ridley explore the Surface of SR388, where they become the first Space Pirates to discover a Metroid.

In Breakout, Kraid makes his most significant appearance in the comics, appearing as a prisoner of Metroid Cell Block 1 on RX 338. He attempts to convince all of the prisoners in his block that were put away by Samus to turn on their fellow captive, pointing out that she is weaponless. Samus punches Kraid, then grabs him by the foot and swings him around as an improvised weapon, beating the prisoners into submission. Samus later uses Kraid as a diversion to make her own escape, and she threatens him into compliance. He is caught by the guards in the watchtowers and presumably spends a month in solitary confinement as punishment.

In When Friends Fall Out, Kraid and Ridley appear in a flashback taking place several years prior to the main story. They capture Samus and connect her to a machine, intending to brainwash her into a minion for Mother Brain. Samus breaks free of their machine and steals their Flame-Chip as she escapes.

Super Smash Bros.[]

Super Smash Bros. Melee[]

Kraid as a stage hazard.

Kraid also appears as part of the Planet Zebes: Brinstar Depths stage. Occasionally, he will emerge from the magma, roar, slash at the arena with his claws, and then sink back into the magma. While he cannot directly attack players, Kraid causes the entire arena to rotate, with the direction based upon how he strikes it. This changes the battlefield and forces players to adapt.

A trophy of Kraid is also obtained when the Brinstar Depths stage is unlocked.

Super Smash Bros. Brawl[]

The Brinstar Depths stage does not return in Brawl. Therefore, Kraid only makes a cameo appearance as a sticker, using his artwork from Zero Mission.

Super Smash Bros. Ultimate[]

Kraid's updated model in Ultimate

Kraid returns in Ultimate along with the Brinstar Depths stage. In addition to being much higher quality than Melee, his model is now more closely modeled after his appearances in Super Metroid and Zero Mission. He plays the same role as he did in Melee.

Kraid appears in Dark Samus's congratulations screen for Classic Mode, where he is seen emerging from the lava at Brinstar Depths while Dark Samus and Ridley are about to fight each other. Kraid also appears with fellow reptilian villains in the image unlocked by completing Luigi's All-Star Smash Challenge.

Kraid is also a Master Spirit, using his artwork from Super Metroid. He is unlocked in the Dark Realm of the World of Light adventure mode, and is a mandatory encounter along the path to the Sacred Land. Kraid's Spirit Battle is a stamina battle against a Giant King K. Rool on Brinstar Depths' Omega Form. During the battle, K. Rool has reduced jump power and movement speed. As a Master Spirit, Kraid cannot normally be equipped by fighters; exclusively during this fight, he is classified as a Neutral type that is neither strong nor weak against other Spirits.

Kraid's Dojo.

Once unlocked, Kraid runs a Dojo, where he trains up to four other Spirits. He teaches them the Tank Style, which increases offense and defense but reduces move speed and jump. As a Master Spirit, Kraid is given dialogue for the first time in a videogame; however, it consists entirely of roars and grunts. Translations are provided in parentheses, although these translations seem to be somewhat uncertain (often guessing what Kraid means or ending with question marks) for added humor. On a similar note, this technically marks the first time that Kraid acts as an ally to the player rather than an enemy.

Nintendo Land[]

Kraid and Ridley animatronics in Metroid Blast

In the Metroid Blast attraction, Kraid is featured as an animatronic robot and is the first boss that Miis must fight in Assault Mission. He appears in the Volcanic Sector during missions "10. Hostile Colossus", "24. Kraid's Army", and "30. The True Final Battle", which all have the objective of defeating Kraid. His battle theme is a remix of Brinstar (Metroid).

He begins by partially emerging from a pool of lava, exposing his head, arms and chest. At this phase, he attacks solely by throwing his classic boomerang-like claws, however they now detonate with a wide explosive radius after a few seconds. The Mii must shoot the presented target on his nose and then fire Missiles (if piloting the Gunship) or Charge Bombs (if on foot) at his throat - after three successful shots, Kraid will rise out of the lava and add to his long-range arsenal by firing Rockets, bullets, lasers and energy spheres from various locations on his body. He also extends platforms from his body which carry Zebesian Pirates, revealing Kraid as a sentient, mobile fortress. The Pirates are not necessary to kill, though they can hinder the Mii by shooting beams from their claws and may try to close-in on the player for melee attacks. Regardless, the Mii must continue to shoot all the new targets spread throughout Kraid's body (including attacking the one on his nose once again) which will expose his throat. After enough damage is inflicted, Kraid will rise higher out of the lava, unveiling more of his large, cylinder-shaped, heavily armed mechanical body. After repeating the process with the targets a third time, Kraid will explode, thus ending the battle.

Another method for killing Kraid is made available to the player if another Mii is piloting a Gunship: the Mii on foot can Grapple Beam with the left arm onto the underside of the Gunship, allowing the player to be carried above Kraid's head and, if the latter's mouth is open, drop down his throat and land inside his chest, where the weakpoint can be damaged with standard beam fire.

"10. Hostile Colossus" just has the Mii fighting Kraid. "24. Kraid's Army" requires the Mii to defeat Kraid under a time limit, while Kraid is accompanied by numerous Cyclons and Geemers to increase the overall difficulty. "30. The True Final Battle" consists of fighting both Kraid and Ridley simultaneously; Ridley can regenerate himself indefinitely, making Kraid's defeat the main goal to completing the mission. As Kraid explodes at the end, so too will Ridley. This duo boss battle marks the only occasion where these Space Pirate leaders fight alongside each other in any Metroid-related video game.

If Kraid is defeated, the Mii unlocks Survival Mode for Ground Battle. His head is also a prize in the Nintendo Land Plaza.

It is preferable that you proceed in top condition. This room has a three-layer shutter. The enemies have not yet noticed you, so you can clearly escape. And since Kraid is the area boss, this fight will not be simple. Will you proceed or turn back?'"
Passage 97
"A dinosaur-like creature with numerous, enormous spikes appeared. Its height was easily around 3 meters. The command computer spoke: 'It's Kraid.'
"Kraid's method of attack is to use his spikes as a weapon, launching them [at his enemy]."
Passage 169
"The command computer issued an alert. 'Without missiles, Kraid cannot be defeated.'
"I shot my beam behind him as a distraction. Using that, I managed to dodge his attacks and fled the room. For the moment, I think I'll leave the area, stock up on missiles and energy, and try again."

Super Metroid manual[]

"The giant lizard of Brinstar attacks Samus with thorny projectiles and spits spheres out of its mouth. No weapons - beams, missiles, or bombs - have any effect on its body. The creature's weak point is unknown."

Super Metroid Players' Guide[]

"By far the largest guardian in the game, Kraid will prove a tough adversary. He only has one weak spot and that's the inside of his mouth. Shoot him in the head then, when he roars in pain, lob as many rockets and laser bolts down his throat as possible. When he first emerges, he pauses with only his upper body showing. Use this time to get in as many hits as possible; he'll then rear up to his full height and your job becomes much trickier. To make matters worse, he will launch a myriad of projectiles from his body. The spikes launched from his chest can be ridden upon if you can get on top but contact anywhere else results in damage being sustained. The spinning claws have to be either shot or dodged. If missiles or energy are running low, try shooting the claws as they sometimes leave bonuses behind. Three super missile direct hits will do for Kraid, but otherwise use normal missiles and charge shots."

Samus (JoyRide Studios)[]

"In Super Metroid for the Super NES, the hulkin Kraid is the boss enemy that resides in Brinstar. The giant's weak spot is its mouth, and you can inflict damage by firing a missile into its mouth when it's open. To get Kraid to open up and say 'ahh,' fire a missile at its face, then shoot another missile into its slack-jawed mouth."

"Fire missiles into Kraid's open mouth to cause damage. If you're out of missiles, use Charge Beam shots."

"When Kraid rises, hop onto one of the platforms that it shoots out of its belly. Use the platform or the Hi-Jump Boots to set your sights on Kraid's face, then blast missiles into the alien's open mouth."

Metroid: Zero Mission manual[]

"The largest enemy in all of the mazes beneath the surface of Planet Zebes, Kraid fires spikes from his belly and claws from his fingertips for extremely powerful attacks."

Official Metroid: Zero Mission website[]

"Extremely dangerous! Giant lizard-like monster over two stories tall. Possesses iron-shredding claws and fires small projectiles from its mouth. When angered, shoots regenerative claws from giant openings in belly. Can be destroyed by hitting soft tissue in mouth with Missiles. DANGER LEVEL: VERY HIGH."

  • "Soft tissue (weak spot)"
  • "Iron-shredding claws"
  • "Regenerative claws"

Super Smash Bros. Melee Trophy[]

Kraid trophy from Melee.

"A boss enemy from Metroid. Kraid lives in the depths of Brinstar. He immobilizes enemies with his three red eyes, and his powerful jaws can crush anything. He can also shoot the three spikes in his belly; it's said he often fires them at his prey. Once Samus defeated Ridley and Kraid, the way to Tourian opened."

Super Smash Bros. Brawl Sticker[]

Nintendo Land[]

"This hulking monstrosity dwells in the depths of planet Zebes. His skin is impenetrably thick, so try shooting into his mouth. You'll have to climb his towering body to reach his face!"

Development notes[]

Kraid's Super Metroid and Zero Mission sprite artists never created the large Pirate's entire tail. By extracting Kraid's sprites from the games' internal files, it is revealed that his tail always ends abruptly; the sprite artists likely ignored this detail since players are never capable (and are not meant) to get behind Kraid and explore the areas beyond him until he is defeated, which results in him sinking into the ground and exploding, thus preventing his tail from being fully viewed. This continues in Metroid Dread, wherein his in-game model does not have legs or a tail.

Kraid's size changes throughout the games. For example, in Metroid, he is about the same size as Samus, whereas in Super Metroid and Metroid: Zero Mission, he takes up two screens. In Melee, he is even larger. This is likely due to the NES' limited processing power being unable to smoothly handle larger sprites. According to the official Metroid: Zero Mission web site, Kraid is over two stories tall, the low-end being three stories. This would mean Kraid is at least 9.9 meters tall (32.5 ft.). When asked to explain the discrepancy of Kraid's sizes in Metroid and Super Metroid, Dan Owsen joked that "He lost his supply of Slimfast [meal replacement powder] when the first planet blew up."[11] This is erroneous as Zebes was not destroyed in Metroid, but it was in Super Metroid.

His roar in Super Metroid and Metroid: Zero Mission is a stock roar sound effect previously heard in films such as The Land Unknown (1957) and King Kong (1976). This roar is shared with Crocomire and Phantoon. In Metroid Dread, his roars are apparently taken from the T-Rex in Jurassic Park. In addition, he is heard emitting a secondary sound whenever shot in the mouth, and to a lesser extent when fully dunked into the lava, which is a high pitched squealing roar, apparently meant to indicate agony.

For Dread, MercurySteam sought to keep Kraid recognizable while showing off a new version of him.[12]


  • Kraid appears on the Super Metroid Stare-E-O Poster.
  • Due to the Reptilicus species possessing three eyes and a reptilian appearance, some fans have been to believe Kraid may be related to the former. The Reptilicus' statues and busts on Bryyo, as well as their Mogenars built with arcane arts and technology, are also tricloptic. On top of this, Mogenar's battle theme is similar to Kraid's, though this is likely to have been an intended homage similar to Berserker Lord's theme being an altered rendition of the unrelated Arachnus' in Metroid Fusion.
  • In the NES Toys "R" Us commercial, "Kraid's Toy Shop" is shown to be sold out of NES games.
  • The Squizzard boss in Super Mario Galaxy 2 bears subtle similarities to Kraid. Such similarities include the weak point being the mouth, and spiked projectiles being fired by the flick of a hand. The Squizzard is also half-burrowed in the ground, similar to Kraid in Super Metroid.
  • The color of Samus's Power Suit during the cutscene with Kraid rising before her in Zero Mission will vary depending on whether or not the Varia Suit is acquired prior to the battle.
  • Kraid in Luxembourgish translates to "Cretaceous", possibly an intended nod to the Pirate's dinosaur-like appearance.
  • The secret means of defeating Kraid in Metroid Dread (entering his body and laying Bombs) may be a reference to a recurring method of damaging the Queen Metroid in its appearances as a boss.
  • In Metroid Dread, Kraid's final stomach spike remains in his boss room after his defeat, but vanishes after the X Parasites are released from Elun.[13] This implies that the purple X Parasite had absorbed Kraid's DNA from this spike.
  • The particular room and manner in which Kraid is held captive in Metroid Dread was seemingly designed by the Chozo to guarantee he would cause his own demise if he ever tried to escape from his restraints.
  • In Dread, if the Hyper-Beam is hacked and used on Kraid during the beginning of the fight, the platform Samus is on will immediately be destroyed and the lower half of the area will be glitched along with Kraid (who will simply be stuck in its idle animation, no longer attacking). This is most likely due to the fight not having a proper transition. Samus can walk around on the lava as if it were a normal platform and even pass through Kraid's stomach. Should Samus enter the hidden launcher to her left, she will then be softlocked with no way out.[14]
