Gravity Antonion

Gravity Antonion, known as Gravitate Ant-Onion (グラビテイト・アントニオン) in Japan, is a new generation Reploid from Mega Man X8 that works in a antigravity laboratory. He is a very intelligent scientist, and is calm and polite. When he became a Maverick, he took control of the tower above the antigravity lab, which has a lot of switches that shift gravity.

He attacks by creating giant cubes above the Hunters to smash them and turning the room to make the cube fall on them (actually, he shifts gravity, but to the characters it feels like room-turning). If the cube falls on him, he will lift it and throw at the Hunters. He can also create a pillar-like object to hit the player when close to him. After losing some health, he will create a large Squeeze Bomb in the middle of the room, and releases a green goo from his back that can hold the player. In Normal and Hard Modes, he can make several cubes fall consecutively after losing some health. He is weak against the weapons gained from Dark Mantis, perhaps partly due to the fact that Shadow Runner and Black Arrow are seeking weapons, and Rasetsusen can hit anything that gets close to Zero when he spins. Another note is that shadows are unaffected by gravity, since shadow is the absence of light.

Trivia

 * The Primrose stage is situated in the northeast of Australia, possibly in Queensland or a nearby island like New Guinea.
 * Oddly, in the battle with Antonion, if one shot him with the Shadow Runner/Rasetsusen/Black Arrow, at the same time he changes the gravity with a block about to fall on him, Antonion doesn't move again from under the block, and one has to restart the level, because the battle simply cannot be finished (as one can't hit him, because of the block, and the block itself can't be destroyed neither).
 * Gravity Antonion's weapon is similar to Gravity Beetle's weapon.
 * Gravity Antonion is similar in appearance to Boomer Kuwanger.
