Magna Centipede (Magne Hyakulegger in Japan) is one of the eight Maverick bosses from Mega Man X2.
Magna Centipede was a Maverick Hunter from the Special 0th Unit under Zero, but when Sigma started his rebellion he had Centipede captured and brainwashed to serve him. Centipede is then ordered to take over a Computer Center, from which he starts to transmit the Sigma Virus around the world to create even more Mavericks to help Sigma. He's eventually confronted and defeated by X.
Magna Centipede will be constantly moving and teleporting around the room, sometimes appearing in the ceiling. He mainly attacks by throwing three shurikens or his Magnet Mine which seeks targets, but he can also attract the player and sting him with his tail, thus disabling one of X's abilities each time. His weakness is the Silk Shot, which breaks his tail thus preventing him from disabling the player.
