A Gadora is a Bio-Barrier that lives on Zebes, but an X mimic is also present on the BSL. They are easily recognizable by their single eye and are generally found blocking entrances to boss rooms. Samus can destroy them by firing three Missiles or one Super Missile at the creature's eye when its eyelid opens. They will sometimes defend themselves by covering their eye with a strong shield which they immediately launch as a wave of plasma from their eye; in other appearances, they shoot three consecutive spheres of plasma which home in on their target. On the Biologic Space Laboratories research station, destroying a Gadora will always produce a Red X, replenishing a large amount of Samus's ammunition and energy. In Metroid: Zero Mission and Metroid Fusion, these creatures can be destroyed with the Charge Beam; this is not possible in Super Metroid however.

Metroid Prime and Metroid Fusion: Prima's Official Strategy Guide refers to these as "giant eyes". Metroid Fusion: The Official Nintendo Player's Guide calls it an "eyeball hatch".

Official dataEdit

Super Metroid Nintendo Player's GuideEdit

"Three Missiles (or one Super Missile) shot into the eye on the door will allow you to access Phantoon's chamber. This is the same technique you should use for entering the lair of each boss in the game."

HATCH-BLOCKING ENEMIES "Destroy hatch-blocking enemies with Missiles."


  • The Gadora has strong similarity to the final boss from Kid Icarus: Medusa, who was also a giant eye that fired energy waves and also leaping serpents. Pit (The protagonist) could only harm Medusa by firing the Sacred Arrows into her eye.
  • EyeballBlocker is a creature in Metroid Prime 3: Corruption sharing many similarities with Gadora; it is possible that the former was modeled as an homage to the latter.
  • The fact that the only Gadoras encountered on Zebes were always found guarding the Pirate leaders' chambers suggests that they are intentionally placed there by Space Pirates as a line of defense; this would also suggest that they are artificially cultivated life-forms and cannot be found naturally in the wild.
  • Strangely, the Gadora guarding Phantoon seems to be decayed, as its flesh is a dead, grey hue.
  • It is interesting to note that the Gadora-X in Fusion are X Parasites who have taken the role of guarding the rooms in which their superiors, the Core-Xs, reside in.
  • In Super Metroid, the Gadora's texture appears on walls and floors nearby the creature itself, suggesting that it "makes a home" out of its location or that the creature itself can spread and grow like a plant/fungus. The texture will not disappear when Samus destroys it. Worthy of note is that in Tourian, it only appears in the organic area, blocking the shaft before Mother Brain's lair.
  • The Gadora seems capable of living indefinitely in Water, as the Gadora guarding Draygon in Super Metroid was seen submerged. Also, an X Parasite mimic or X-infected Gadora is found submerged in a pool of water in Sector 4 guarding the Serris mimic in Metroid Fusion.
  • The 'eye' security system, one of the many Pirate Alarm Systems seen on Chozodia in Zero Mission, shares similarities with the Gadora (as it is an eyeball on a wall that shoots projectiles quite similar to the latter's).
  • It is likely that the Gadora blocking Kraid in Super Metroid was responsible for the death of the "Deceased Soldier".
  • Its name appears to be a rough portmanteau of the words "guard" and "door", the function which it serves.
  • The Gadora guarding Kraid in Zero Mission only takes one Missile to kill.
  • The Gadora has never made an official 3-D appearance.
  • The battle mechanism of the Slench being an eyeball only vulnerable when the eye is shot is similar to the Gadora.
