Balrog

Balrog, known as M. Bison in Japan, is a character from the Street Fighter series that works for Shadaloo. He appeared in Street Fighter X Mega Man and Worlds Unite.

Street Fighter X Mega Man
Balrog appears as the first of M. Bison's minions that Mega Man will fight upon clearing the areas of the eight main bosses. He follows Mega Man from behind, unleashing unlimited barrages of a super attack that will instantaneously eat Mega Man's health should he catch up to Mega Man and successfully land a hit. Though Balrog's style is impetuous, his defense is not impregnable against Mega Buster fire. However, a far easier way to defeat Balrog is to just keep running to the right; eventually Balrog will fall into a pit opened by falling tiles that drop after being traversed by Mega Man. After defeating Balrog, Mega Man can quickly slide as far as he can to the right before the stage ends to get a hidden E Tank.
