Gravity Antonion, known as Gravitate Ant-Onion (グラビテイト・アントニオン)[3] in Japan, is a Maverick from the X era, appearing as one of the main bosses in Mega Man X8. He is a gravity-themed Reploid based on an ant, who attacks by summoning cubes and forming black holes. He is a new generation Reploid who was a scientist in an anti-gravity laboratory.

In the Games

Mega Man X8

Gravity Antonion debuts in Mega Man X8 as one of the eight Mavericks on the Stage Select screen. He is a new generation Reploid who rebels by building a tower atop the anti-gravity laboratory to serve as his base, serving as the boss of the Primrose stage. In battle, he walks up and down the walls freely as he attacks with a wide arsenal, occasionally rotating the arena. Defeating Gravity Antonion grants Squeeze Bomb to X, Juuhazan to Zero, and Spiral Magnum to Axl. His weakness is the Shadow Runner, Rasetsusen, or Black Arrow from Dark Mantis, which briefly stuns him. A boss attack rematch with Gravity Antonion later occurs in the Gateway stage.

Other Media

  • In the Archie Mega Man comic, Gravity Antonion appears in the "Worlds Unite" arc as one of the Mavericks resurrected in Sigma's army.
