Wheel Gator

Wheel Gator, known in Japan as Wheel Alligates (ホイール・アリゲイツ), is a Maverick in Mega Man X2 modeled after an alligator. He was an officer serving in the Maverick Hunters' 6th Navel Unit along with Bubble Crab (the two did not get along). Gator was later discharged, hunted as a Maverick and a traitor after viciously attacking a fellow Hunter. To satisfy his destructive impulses, he joined Sigma's army and was given control of a massive dinosaur-modeled tank, which he tried to use to raze an entire city.

Strategy
When you face him, the room is flooded in some sort of sludge (perhaps oil). He'll throw his Spin Wheel at you, which can also climb up walls. Stay on the walls unless you're chased by the wheels, as if you stay in the sludge, Wheel Gator can grab you in his jaws and chomp you, causing serious damage. His weakness is Strike Chain, which can really put a dent in his power.
 * In Mega Man Xtreme, he falls prey to Magnet Mine.
