Overdrive Ostrich, known in Japan as Sonic Ostreague (ソニック・オストリーグ Sonikku Osutorīgu), is an ostrich-type Maverick in Mega Man X2. Overdrive was once a Maverick Hunter of the 7th Airborne Unit, but retired after an accident that cost him the ability to fly. Sigma later sought to recruit him, seeing use for his superior speed. Overdrive, sensing appreciation for his abilities, pledged his loyalty to Sigma and was stationed at an abandoned missile base; charged with the task of launching the one remaining missile stored there at the Hunter Base. Before confronting Overdrive, X manages to destroy this missile just as it launches.


He is one of the few Mavericks with an outdoor battle arena, which may be the largest in any Mega Man game to date. Mega Man Zero sports a close-to-identical battle arena for the battle against Fefnir.] His most common attack is a charging run, which is easily dodged by jumping over him. He will also perform another style of run, in which he will jump and kick across the screen with just enough room to run or dash under. Overdrive tends to always use his Sonic Slicer in its charged state, by jumping high and firing six energy boomerangs that rain down on the battlefield. And, one unique attack that he will perform, is he will run off screen out into the desert (background) and then jump back to the foreground to try and land on X; to avoid being stomped just keep moving. He is weak to Crystal Hunter, which will both damage and freeze him, but once he thaws he will immediately counter with Sonic Slicer. It is possible to cancel his counter by just freezing him again just as he thaws (trapping him in a continuous loop), but your timing must be spot on. He is also vulnerable to Silk Shot.

Zero, in Mega Man Xtreme 2, can take him on with Lightning.

  • For X-Buster, the four damage values are listed according to how long the weapon is charged. Note however that the forth number is damage done with the second shot when the X-Buster is charged all the way.
  • For Silk Shot, the first set of numbers is damage dealt to them in their own stage; second set is damage dealt in the X-Hunters' fortress.
  • For Giga Crash, value listed is the total amount of damage done.
  • For Shouryuken, using this will generally defeat this boss in one hit, however it does not inflict a set amount of damage; the amount of damage done is dependent on how close X is to the boss when preforming it.





  • Overdrive Ostrich is the first boss in the series to use an attack that involves use of the background.
  • Overdrive Ostrich is also the only boss in the series to receive a shift in his weakness order: as of X2, the Sonic Slicer was used to defeat Wire Sponge and his Strike Chain. In Xtreme 2, however, it is now the reverse, which is rather ironic.
  • In the Rockman X manga by Yoshihiro Iwamoto, Overdrive Ostrich served directly under the command of Storm Eagle prior to Sigma's first revolt, where he experienced his accident that cost him his ability to fly. He only joined the X-hunters after being presented with the remains of Eagle's Storm Tornado cannon, seeking to avenge his ex-commander. Despite his revolt, he eventually redeemed himself by sacrificing himself to stop a missile launch, after seeing Eagle's courage within X.
