Kihunters,[1][2] also referred to as Keyhunters[3] or simply Hunters,[4] are a race of insect-like beings that have joined with the Zebesian Space Pirates. They appear in Super Metroid, Metroid Fusion and Metroid: Other M.

Kihunters are allies of Space Pirates and hail from another galactic system; according to Super Metroid's manual, they are pirates who traveled to Zebes to assist in the reconstruction of the planet's Pirate bases. Whether this means they are Space Pirates as a species or merely in profession is unknown. In Other M, the Kihunters are shown to possess a very insect-like organization/hierarchy within their race, with a King Kihunter seemingly leading them. Their method(s) for space travel is unknown.

The only planet that they are seen inhabiting in the Metroid series is Zebes. They have wings, allowing them to fly, and can spit acid from their mouth, though they mainly charge their opponents while swiping at them with their claws. If they lose their wings, they will only spit acid and travel by hopping.

In Super Metroid, they can be found in large numbers in several areas on Zebes, with the creatures' colors appearing to adapt and blend in with the surrounding, and sometimes harsh, environment. There are three different colored Kihunters, and the weakest to the strongest variant are as follows: green for Crateria and Brinstar, dark yellow for the Wrecked Ship and red for Lower Norfair.

A King Kihunter.

Kihunters also appear in Metroid: Other M in their first 3D appearances. The Kihunters here are a shiny blue-green color and, for reasons unknown, now possess six limbs instead of four. They appear in the Biosphere of the BOTTLE SHIP; like most creatures within the ship, Kihunters were being experimented as bioweapons by corrupt factions within the Galactic Federation. Early in the game, Samus is forced to go through their nest and must defeat their King. In this game, Samus can remove their wings by firing a Power Beam Charged Shot or rip them off using the Overblast technique. When they are unable to fly, Kihunters will slowly approach Samus and suddenly jump at her in an attempt to cling to her. If successful, they will sacrifice themselves by exploding (an ability never before seen), causing considerable damage to Samus. However, when grounded they are susceptible to a Lethal Strike where Samus spins them around before throwing them, damaging any other Kihunters in the way in the process. They are often found near Zeros, their larval stage, and some Zeros may quickly molt to become Kihunters in a matter of seconds. Samus indicates surprise at encountering them, wondering about the return of the "beelike creatures."

In Metroid Fusion, Kihunters have been infected and mimicked by X Parasites. These Kihunters have a slightly different head structure from the ones seen on Zebes and the BOTTLE SHIP; they now possess a beak-like mouth and their foreheads are colored purple instead of yellow. They can be found in Sector 2 (TRO) and parts of the Main Deck of the Biologic Space Laboratories research station. Unlike the BOTTLE SHIP's Kihunters, which were being converted into living weapons, those onboard the BSL were seemingly being observed for research purposes before X Parasites infested the station. Prior to their appearances, Samus encounters X-infected/mimicked Zeros at first. These caterpillar-like creatures are eventually witnessed entering a pupa stage and later on hatching from their cocoons as Kihunters, still infected/mimicked by X Parasites: this sequence of events was the first to reveal that Zeros were actually infant/larval Kihunters.


Super Kihunters[2] are featured in Other M. They are generally more durable, with crystallized structures and a darker skintone. These seem to be an advanced stage of the Kihunters' life cycle onboard the BOTTLE SHIP.

The second variation is the previously mentioned King Kihunter, which is a large, mostly immobile creature connected to a central part of its hive. Its physiology is vastly different from a regular Kihunter's.

A Kihunter in Smash Run

In Super Smash Bros. for Nintendo 3DS, Kihunters appear as enemies in the Smash Run mode. They are visually modeled after their appearance in Other M, but they behave more similarly to their appearances in the 2D games. They can be found flying in the air, and will attack by either spitting acid or charging with their stinger. The Kihunter's acid can penetrate shields and briefly paralyze fighters. Like all other Smash Run enemies, Kihunters also have an unlockable Trophy in this game.

In Super Smash Bros. for Wii U, several Kihunters are included in the King Kihunter's Trophy.

"Kihunters, which look like flying ants, appear in groups. Despite losing wings when injured, they will crawl on the ground toward Samus."

Super Smash Bros. for Nintendo 3DS Trophy[]

"Creatures hailing from the Metroid series. They start off life as a Zero, growing into this bee-like form. Kihunters prefer to attack with quick dashes and by spitting gobs of acid. Definitely dodge the acid— it stuns you and goes through shields. Defeated Kihunters drop Jump stat boosts."
"These insectoids from the Metroid series emerge from their larval form known as a Zero. Kihunters attack by either charging at you from above or spitting acid. That acid can paralyse you, and it'll even cut through your shield, so dodge to avoid getting hit. If you defeat a Kihunter, you'll get Jump stat boosts for your troubles."

Super Smash Bros. for Nintendo 3DS Tips[]

"These insectoid enemies spit acid at you from the air. Touching the acid will paralyze you for a short time."

"Kihunters won't spit acid at you if they're below you. Fighting them from above is an excellent strategy."


Possible Kihunter eggs in Brinstar.

  • In the internal data of Super Metroid, Kihunters are referred to as Hachi. The dark green Kihunter is Hachi1, the pale green Kihunter is Hachi2, and the red Kihunter is Hachi3.
  • The room directly before facing the Spore Spawn is filled with Kihunters and small, unknown structures on the ceiling resembling eggs. Since both the flying creatures and the egg-like objects are found in the same room, it is possible that the latter are Kihunter eggs (containing future Zeros).
  • Kihunters are curiously located far from any Zero in Super Metroid, the game where both creatures made their first appearance.
    • However one Crateria room has a Zero initially programmed as a placeable enemy within the same room as a Kihunter(s) but is never implemented. Instead a Sciser, a similar functioning enemy, is placed there instead.
  • While Kihunters are known to be Space Pirates in Super Metroid, Samus curiously makes no mention of this in Other M. In fact, Kihunters appear to have no affiliation with Space Pirates in that game and in Metroid Fusion. However, their feral nature in both games can be easily explained by the lack of a proper education and/or a supreme Pirate leader, just as how Zebesians in the BOTTLE SHIP are steadily losing their intelligence without the presence of a controlling force like Mother Brain.
  • The ability to self-destruct is a trait that is only seen in the Kihunters living inside the BOTTLE SHIP in Other M. It is possible that the scientists and researchers on board the station added this ability to the species in order to turn them into more efficient bioweapons.
    • In real life, there is a species of ant called the Camponotus saundersi which can commit a suicidal explosion by contracting its abdominal muscles, causing its mandibular glands to burst and spray a corrosive chemical secretion.
  • The Kihunters are the only creatures who aren't damaged by an Overblast.
  • The Kihunters are the only creatures who do not receive a Charge Beam shot during Lethal Strike.
  • In Other M, a Kihunter can grab Samus if it has its wings. It then damages her by "pecking" her neck. If Samus is killed while in the Kihunter's grip, she will simply go limp in its arms, instead of the normal death cutscene.
  • In Other M Kihunters have a similar fighting style to the Aerotroopers from the Prime series. Both will also attempt suicide strikes when near death.
  • The BOTTLE SHIP's Kihunters seem to be symbiotically related to Whipvines: five of the plants can be seen on the supports surrounding the Kihunter hive on the Biological Experiment Floor, and will attack Samus in a coordinated pattern along with the Kihunters. Whether this is a natural relationship or the result of MB's tampering is unknown.
  • While Kihunters have yet to appear in the Prime series, there have been some similar enemies:
  • A Kihunter appears on the Super Metroid Stare-E-O Poster.

They travel in large groups and can overwhelm you with their numbers if you're not careful. They never set foot on the ground, by choice, so always keep an eye to the sky to make sure you can spot them. Bring them down with a few Charge Beam blasts, or use Lethal Strike moves to tear off their wings. Once you've grounded them, finish them off with Lethal Strikes, missiles, or Charge Beam shots. The only difference between Kihunters and Super Kihunters is the Super Kihunter's ability to withstand a bit more damage." Metroid: Other M Premiere Edition, Pg. 10
