Mogenar is a Mogenar-class War Golem that was summoned to be the guardian of the Bryyo Leviathan Core. It is a boss in Metroid Prime 3: Corruption.


The only completely functional Mogenar that Samus encounters is the one located in the Leviathan seed on Bryyo, which has been infused with Phazon spouting out of the Leviathan's very core and thus gone rogue. It boasts an imposing figure that, while not on the level of the massive Quadraxis or the gigantic Space Pirate Kraid, is at least eight times taller than Samus, with an immense frame that causes it to resemble some kind of Mesoamerican idol. It has three eyes on its reptilian-looking face, keeping in touch with its Bryyonian origins.

All evidence seem to point to that the Mogenar faced in Bryyo's Seed was one of the special Golems built out of stone by the last Lord of Science. Taking into account the advice given to him long ago by the Chozo, the special Mogenars were built using both the ancient "magic" of old and the highest technology of new; these War Golems had advantages over the purely-mechanical Mogenars (which are seen scattered throughout ruins of Bryyonian society) built by the other Science Lords.


When Samus approaches Mogenar, it activates, and using a unique ability, uses a form of immaterial projection of its hands to pull four red energy orbs off nearby pedestals, putting two into slots on its shoulders, one on its belly, and one on its back. These orbs act as Mogenar's weak points and energy generators, and all four must be destroyed; at first, any weapon can be used to damage them, but once it explodes, Phazon energy from Hypermode must be used to blow up each slot, rendering it useless. The three spheres on the golem's front can switch positions to avoid damage.

Mogenar awakens.


Its attacks include ramming charges, energy streams, jumps that release a Phazon shockwave, generating additional immaterial hands to attack Samus directly, slamming its hands against the floor to create a massive barrage with Phazon rocks, or, when its energy orbs are near destruction, standing in the middle of the room and using its immaterial hands to retrieve more unharmed spheres from the pedestals of the room to regenerate its damaged ones. If Samus is quick enough, the orbs can be destroyed before they make it to Mogenar. Also if Samus uses an Ice Missile while Mogenar is using its laser breath, its face will be temporarly frozen, leaving the energy orbs vulnerable to attack.

Battle continued[]

After destroying Mogenar's first sphere and overloading its Phazon core, Mogenar will generate a form of Phazite on its feet for additional invulnerability, though this limits its attack range to only two attacks: its ramming dive and its shockwave jump. These Phazite platings can be destroyed by simple Morph Ball Bombs, but Samus should be wary of staying in Morph Ball too long; the shockwave blast the Golem employs is too tall to be jumped over with the Spring Ball. When the second of its energy orbs has been destroyed, Mogenar no longer uses its former regeneration technique; rather, the last remaining sphere on its front will start acquiring more and more armor as time passes, and speed is necessary to blast off the sphere's cap before it regenerates and overload it with Hypermode. When three of its spheres have been destroyed, the beast no longer can defend itself adequately and is mostly reduced, again, to its ramming dive attack and shockwave, though it can still throw in any of its attacks in-between. The last orb on its back will be exposed when its back is turned to Samus after its ramming dive, but it needs to be hit quickly before Mogenar turns around again. Also Samus can go into her Morph Ball and go around the back of Mogenar as the Morph Ball is faster than the side dashes; again, Samus must be quick before Mogenar turns around.

When the final orb is overloaded, Mogenar explodes, leaving behind the Hyper Ball upgrade and raising Samus's corruption level to 25%, which in turn causes Samus to vomit Phazon.

Orbs appear to be source of power.

Phazon Crystals are powering a protective barrier. An explosion near his feet could probably destroy them.*

Logbook entry

Corrupted War Golem reanimated and energized with Phazon. Relies on socketed energy orbs as a source of power. The orbs themselves have a fragile exterior but contain pure Phazon energy within. This energy must be completely overloaded before it will be destroyed. Eliminating all power sources is the only way to bring Mogenar offline.

Before battle
"Ancient Reptilicus War Golem appears to be receiving energy from the core of the Seed."
Orb broken
"Shattered orb has exposed a Phazon core. Overload the core with Phazon energy to destroy it."

Unlockable concept art of Mogenar from the game.

  • Due to his reptilian appearance and three eyes, Mogenar bears a resemblance to Kraid. Also, Mogenar's boss music is similar to the battle theme of Kraid in Super Metroid and Metroid: Zero Mission.
  • Mogenar is the only boss who is found directly under the Phazon Core and is receiving energy from it.
  • Samus can freeze Mogenar's face solid by firing an Ice Missile while it is doing its mouth-based Phazon Beam attack or any other time it opens its mouth, causing it to flail its arms around while fruitlessly trying to remove the obstruction. Freezing Mogenar's face is also strategically useful, as all its orbs will be open to attack while it tries to bite its way out of the ice.
  • Mogenar's orb holders resemble Morph Ball Bomb Slots. It is possible that it was compatible with Morph Ball Bombs in its normal state (like other Bryyonian Golems encountered in the game).
  • Mogenar's two upper orb holders look similar to the rounded shoulders of Samus's Varia Suit or those of certain Chozo Statues. It is possible the Bryyonians who built Mogenar had been in contact with the Chozo and had based the golem's design off of the latter's.
  • Some players may find Mogenar harder to defeat than some later bosses in Corruption, mostly due to its size, which makes many of its physical attacks such as the ramming dive difficult to dodge, and the fact that Mogenar's multiple weak points make it hard to use Hypermode to attack it, since Hypermode can only be entered a set number of times based on how many Energy Tanks Samus obtains. At this early stage in the game, Samus can collect very few Tanks, thus using Hypermode to defeat Mogenar rapidly can leave her at a disadvantage, with low health and no remaining Energy Tanks.
  • The explosion of Phazon after Mogenar's defeat is the cause of Samus's visor turning from green to turquoise, contrary to the popular belief that the X-Ray Visor upgrade caused the change. This effect of Samus's Power Suit becoming more and more blue in color gradually builds up with each following increases of corruption: Helios's defeat, Omega Ridley's defeat, and landing on Phaaze.
  • Mogenar, or a very similar war golem, is depicted in two of the Bryyo Lore plates ("The Hunted", located in the Jungle Generator room in Bryyo Thorn Jungle, and "Our Plea" in Imperial Caverns within Bryyo Ice). The first plate explains the creation of the special Mogenar golems that use both "magic" and science, and is the only one on Bryyo that can be re-scanned at any time.
  • Mogenar's concept art depicts its spectral hand attack with the caption "Hand Of Ur".
  • Mogenar can be observed roaring, laughing, and otherwise displaying emotional reactions during its battle with Samus, suggesting that it possesses considerable intelligence, if not true sentience.
  • Mogenar's battle is similar to Thardus, in that both are made of inanimate objects, and yet are energized with Phazon to come "alive".
  • Mogenar is also similar to Metroid Prime, as when it uses different attacks, a different color flashes on the Golem (namely white, purple, yellow and red, representing the four beams in the first game).
  • If Mogenar is somehow skipped and defeated after defeating Helios or Omega Ridley, Samus's corruption level will revert back to 25%.[citation needed]
