After having won a street fighting competition in Kyoto and Tokyo Ken made his move to the USA and back to show off his skills in legal competitions by entering the squared circle. Just a big kid at heart, Ken shows off his prowess and martial arts abilities in the ring and shows no mercy when forced to take drastic measures when he needs to take it to the extreme. Recently Ken has had the dark heart of his martial arts begin to take over his psyche and is now Dark Ken.
