Flame Stag

Flame Stag (also known as "Fraim Stugger") is one of the Mavericks of Mega Man X2. Flame Stag leaps about in his chamber (which is perhaps the first boss room that is larger vertically than horizontally), trying to charge into you and throwing fireballs from his Speed Burner. Being a Fire Maverick, he's naturally weak against water, so use Bubble Splash if you have it. In fact, with proper use and timing, you can trap him in a sort of pattern.
