Same as Chun-Li, I did one test match and found out I could abuse the CPUs.

He's decent in speed for a big character, he deals a lot of damage, has a variety on his moveset... But he's a charge character. I didn't get to play as him naturally because I spent all of my time either spamming the same move or trying desperately to do a charge super. I don't think I'd like to talk about him because his gamestyle just isn't the one for me... I don't like to play big strong huge humoungous characters, let alone charge ones. At least Chun-Li has a fair set of non-charge supers

I managed to get 2 PERFECTS with him (one on the final battle) but that doesn't make him any better... The CPU really went stupid when I started spamming Down + HK (Slide) and HP, it forgets how to Alpha Counter or even Block properly.

what??.,.,, Bison yaoi? with ryu real??? I hate Bison

Bison wants to experiment with Ryu's Satsui no Hado. Yeah.

In Street Fighter Alpha 2: Gold, he has an EX version, and he can do a meterless Psycho Crusher. That's it, I hate Psycho Crusher, I only managed to perform the input twice and never again in the entire run. I also hate Bison, and also I hate charge moves.

In Alpha 1, there's a secret Dramatic Battle mode where you and a 2nd Player can battle against Bison as Ryu and Ken,.,. It's one single fight based on the one from Street Fighter II: The Animated Movie, it even has the music from there in the Japan version, and he's really... really tough to deal with (unless you just trap him)

He's called Vega and Balrog in other localizations, other people just call him Dictator for better identification... but who cares about that? Really, Bison fits him perfectly as a name because it's ugly as heck.
