In all games where he appeared, the room has sludge if Mega Man X doesn't prepare. Wheel Gator will first roll into Mega Man X and then shoot projectiles. Mega Man X will have to use the walls to avoid until they're damaged. Gator will then throw Spin Wheels in the arena, so Mega Man X has to avoid them. After that, Gator is gone, and if X stays too long, he'll jump to grab him and chomp him like a crocodile, and then Gator repeats again. It's best to use the Mega Buster, because the Strike Chain can last the battle long.
