Fo is an ancient,
bloodthirsty assassin, but often disguises himself as a kindly magician. He
participated in the first two Toshinden tournaments and afterwards, visited Bayhou.
He passed down his iron claws to the creature and trained him in his fighting
It is believed that Fo was then killed
by Bayhou, since he carries a skull on his back that resembles the shape of
Fo's head and also because Fo's model used as a hidden outfit for Bayhou
depicts him as a zombie with a bloody claw mark on his back.
