Street Fighter Alpha 3

You knew Bison had to end up on this list somewhere, but which incarnation? We’re going to go with the intimidating version from Street Fighter Alpha 3, where his "Psycho Crusher" can take more than half your life bar if he hits you with it.

It’s all downhill from there as the leader of Shadaloo gets even more serious on the harder difficulties. M. Bison is definitely one of the most sinister bosses in gaming history so he just had to make this list. He had to.
