Billy Mitchell is.. Mister X?

It just occurred to me that Billy Mitchell, former Donkey Kong world champion, greatly resembles Mr. X, the leader of the evil syndicate from Sega's Streets of Rage video games:

Billy Mitchell

Mr. X

Now, don't get me wrong. I certainly don't begrudge Mr. Mitchell any of the success he's had in his life. Despite the fact that The King of Kong: A Fistful of Quarters portrayed him in a completely negative light, Bill Mitchell is a very successful man worthy of respect.

I just found the similarity to be a bit striking.
