Jo-Ken is the spirit of Ken Turner who lives inside Joe. Not even death could tame this strong-willed family man. He fights the pull to the afterlife to seek revenge on those who hurt his family and murdered him.

 

Jo-ken rears his head whenever he feels like it, much to Joe's disdain. Joe has no control when Jo-Ken takes over, and when he does take over - Jo-Ken is definitely not joking.
