Omega Ridley is Meta Ridley infused with Phazon; this infusion has increased his incredible power to far greater heights. He acts as the Guardian for the Leviathan Seed on the Pirate Homeworld and is the third to last boss in Metroid Prime 3: Corruption.


Following his severe loss against Samus during the failed invasion of Norion, Meta Ridley managed to escape (or was retrieved by the Space Pirates) and exposed to massive amounts of Phazon, energizing him to a new combat threat level. He has a very durable, Phazon-enhanced armorskin and protective armored plating. However, he has an injury from his fall on Norion that has not yet fully healed, which is his only weak point (similar to the one in Metroid Prime). He will try to protect this injury, requiring Samus Aran to stun him and leave the injury open for strong attacks.[1] Samus encounters him on the Pirate Homeworld protecting the planet's Leviathan. After a long and difficult battle, the bounty hunter defeats Omega Ridley, causing him to explode into clouds of Phazon.

Compared to his previous form, Omega Ridley appears to have significantly less mechanical components, with the remaining machinery slowly being pushed out by his regenerating organic flesh. This is likely a result of his Phazon-enhanced healing process in the wake of his defeat on Norion.



Omega Ridley appears.

Initially, Samus must stun Omega Ridley by shooting at his mouth while it is open and glowing (in midair or ground level, the former resulting in him falling to the ground). She can then use the Grapple Lasso to rip off Omega Ridley's armor and overload his heart with Phazon. Alternatively, she can drain Ridley's own energy using the Grapple Voltage, which turns out to be to her advantage, as it allows her to replenish energy used up by attacking with Hypermode attacks. When his weak point is being damaged, Omega Ridley attempts to turn and move away from Samus, but will renew his offensive when his armor inevitably reseals itself.

After this process has been repeated a number of times, Omega Ridley's armor will be completely destroyed. In response, Omega Ridley will back up and generate a new piece of Phazite armor. This time, the X-Ray Visor must be used in co-operation with the Nova Beam to penetrate the Phazite armor, either by striking his wound directly or by weakening the armor's hinges and destroying it (the latter method is preferred, since the wound takes very little damage at this point). Apart from the change in targets, the method of attack is unchanged: stun the boss and attack the weak spots.

After this phase, Omega Ridley will give up on protecting his weakness, taking to the air with his wound exposed. He constantly flies in and out of the Leviathan, reappearing randomly from one of four different entrances, launching an attack before fleeing once more. At this stage, the wound is difficult to target (although watching the radar may help predict where Ridley will approach from), but Samus is free to fire at will with Phazon attacks. It is recommended to enter and exit Hypermode when Ridley appears and leaves the arena in order to conserve energy. After a few hit-and-runs, Omega Ridley may choose to resume his ground assault for a time, which gives Samus a prime opportunity to finish him off.

MP3 Omega Ridley's Death

Omega Ridley is defeated.

The Screw Attack is one of Samus's most helpful items in this battle. Screw Attacking toward Ridley will cancel whatever move he is attempting to execute, as he will instead jump out of the way to avoid being rammed by the attack. Since several of his attacks are either difficult to dodge or simply waste time by making him temporarily invincible, the ability to control his movement pattern can be a great boon in this battle.

Samus receives the Hyper Grapple after defeating Omega Ridley, who disappears in a massive flash of Phazon after the battle.


After being infused with Phazon, Omega Ridley's abilities have been greatly augmented. His attacks include:

  • A massive line of plasma and flame from his Kinetic Breath Weapon.
  • A large blast of Phazon from his tail (used when Samus is relatively close to his rear).
  • Spinning in place while firing both of the above attacks at once.
  • Large or small homing fireballs previously used in the Norion battle (reminiscent of his fireball attacks in 2-D Metroid games). The large fireballs move faster and cannot be destroyed, while the small ones have better homing ability and come in groups.
  • A relatively fast charge. Telegraphed by Ridley opening his wings and turning his head to one side.
  • A claw slash covered with a Phazon blade (identical to the Omega Pirate's).
  • A shockwave attack similar to the Ultrathermal Flamestrike Projector, telegraphed by Ridley jumping and hovering over the center of the room for a moment. Shooting Ridley in the mouth when he jumps will send him to the ground, stunned.
  • Another shockwave which produces an electrical cage-like structure via (destructible) Phazon orbs during the second phase. Destroying one orb will reduce the structure to its "posts" of energy, allowing Samus to slip between them to avoid damage. Destroying both orbs will automatically stun Ridley.
  • Pounding Samus with one hand.
  • Biting Samus if she is too close. This can cost her an entire energy tank on higher difficulties.
  • Meson Bomb Launcher: Carpet bombing the entire area. Only done in flight.
  • Shooting a spread of homing fireballs from his mouth.

Initially, Omega Ridley will mainly attack with his fireballs and Kinetic Breath Weapon, using his shockwave and charge attacks periodically. When the second phase begins, he adds the spinning breath/tail attack and the Phazon orb shockwave to his repertoire, in addition to using his charge and shockwave more frequently. After losing his second set of armor, the Space Pirate commander will alternate between flight and ground phases. By then, Omega Ridley will be noticeably more aggressive and will constantly attempt to close in on Samus by running and/or leaping towards her. While he can still be stunned in the final phase of the battle, he will now clumsily walk and make small jumps to reach Samus and proceed to swipe his claws at her, making it fairly difficult to aim for his heart.

Logbook entry

Revived and regenerated through Phazon exposure, Omega Ridley has been energized to a new combat threat level. Target retains extremely durable, Phazon-enhanced armorskin, as well as protective armored plating. Scans indicate that a recent injury has not fully healed: expose and target wound to inflict damage. Target will act to protect this vulnerability: seek ways to stun the enemy and leave it open for deadly attacks.



Sonny Santa Maria beta animation.

  • There is a glitch that makes Omega Ridley get stuck in the wall when he does his tackle attack that makes him unable to move. If this happens, the battle cannot continue and the game must be reloaded.
  • This battle is similar to that of Meta Ridley in Metroid Prime, as he uses many of the same moves. Curiously, Omega Ridley starts flying around the battlefield when he is at about a quarter health, whereas he is airborne for the first three quarters of his health in Prime.
  • Despite this form being named "Omega", he is relatively sluggish compared to his Meta Ridley form back in Tallon IV. Several attacks, such as the tail swing and tackles, are actually performed at a much slower speed in Metroid Prime 3: Corruption despite Omega Ridley using his arms and legs simultaneously to initiate said attacks compared to when he simply used his hind legs in the first Metroid Prime game.
  • Interestingly enough, Ridley's mechanical implants are more visible in this form, rather than his Meta form on Norion near the beginning of the game, where he appears to be more organic. Also, Omega Ridley's organic purple body is more evident as well (when compared to his previous Meta forms).
  • It is unknown how or why Omega Ridley transformed back into his natural, uncorrupted organic form seen in Super Metroid. It is known however that Phazon has healing properties and that following the destruction of both Dark Samus and Phaaze, the mutagenic substance vanished from Samus' body and elsewhere on the galaxy; these two facts may have played a role in Omega Ridley's regression back to regular Ridley.
  • Unlike Mogenar and Helios, Ridley's disintegration upon his defeat is not seen: Ridley is only seen wrapping his wings around himself and sinking to the ground as an explosion of Phazon engulfs him - the scene then cuts to the resulting Phazon hitting Samus.

Omega Ridley on the Radar.

  • Omega Ridley is the only enemy in the Prime series to be displayed in the Heads-Up Display's Radar as a full-scale silhouette. His silhouette is made of of several blips. All other enemies (even Meta Ridley, both in the first Prime and the beginning of Corruption) merely appear as one blip.
  • Omega Ridley's weak point is similar to the weak point of the Ridley Robot in Metroid: Zero Mission. The latter may be a prototype/precursor to the true, resurrected Meta Ridley, and Omega Ridley is Meta Ridley enhanced with Phazon.
  • The fireballs that he shoots out in both battles in Corruption can be destroyed with Samus Aran's weapons, specifically reminiscent of the fireballs he used in Zero Mission.
  • If Samus jumps at Omega Ridley with her Screw Attack, he always jumps to the side. This will cancel any attacks Ridley is preparing.
