Flame Mammoth

Flame Mammoth ("Burnin' Noumander" in Japan) is a Maverick in Mega Man X. He can spit oil as well as throw flames. His room is also quite large, meaning he can go off screen where your shots can't hit him, but his still can. For fun, use Boomerang Cutter to cut off his trunk. Not only is this good for a laugh, but it also prevents him from changing the conveyor belt's direction. And use the regular (un-charged) Storm Tornado to take him down. In Mega Man Xtreme 2, Marine Tornado will also do the job against Mammoth.
