Old UFC, and Pancrase fans may remember Genki Sudo, an elite level grappler known for his slick ground game, unorthodox (but effective) standup game, incredible walkouts, and dancing while in the ring.
Sudo only fought 3 times in the UFC, and finished both of his wins. He finished his career with an overall record of 15-4 with 13 of his wins being finishes before retiring in 2006.
