Violent Ken



Yep!  It was only a matter of time before Capcom decided to make an "Evil Ken".  First there was Evil Ryu, then Shin Akuma, then Dark Sakura.  Now, we have Violent Ken.  Violent Ken makes his debut in SNK vs. Capcom: Chaos.  As of right now, I don't know how to play as him, but if anybody figures it out, then by all means let me know!  One thing that I do know though is that Violent Ken picks up the Ashura warp (teleport) that Akuma is known for as well as a new super that is a combination of the Shippu JinRai Kyaku and Shoryu Reppa.
Here is the original page that I got these pictures from:
It's Fighters Generation by the way...
And here are some videos of Violent Ken in action...

There are 2 videos of Violent Ken available.  For the first one, you have to sit through a fight between Dan and somebody else first.  Then, the fight will jump to some dialouge between Violent Ken and Ryo Sakazaki (art of fighting).  The 2nd video continues the fight between Violent Ken and Ryo before moving on to a different opponent.
