Fulgore from Killer Instinct. He was one of my favorites in the game because he was an evil killer robot. I really liked the sound effects they used for him and his theme song which vaguely echoes the Terminator 2 opening credits theme. I've been meaning to do a fan art of this guy for years now, I will probably revisit him again and work on properly re-designing him with more time instead of a quick 3 hour job.
