Wire Sponge (Wire Hetimarl in the Japanese version) is one of the eight Maverick Bosses in Mega Man X2.
Created in one of Sigma's labs, he had an accident in which he was given a multiple personality disorder. This accident made him become childish, but even so he had impressive combat abilities, so Sigma left him in charge of the Weather Control Center, where he started playing with the weather systems installed there.
Wire Sponge's fights by using his Strike Chains, which he can spin to defend himself or launch it like a whip. He can also latch it to the ceiling, after which he will shoot seeds around the arena. When on half health he will also draw electricity to cast lighting bolts. His main weakness is the Sonic Slicer, but he is also vulnerable to the charged X-Buster and the Speed Burner. If the player defeats him with the Sonic Slicer, he will be cut in half before exploding.
