Yono the Destroyer
Voiced by: Clancy Brown
A new villain introduced in the Season 4 episode Oh No! Yono. Released by Monkey Fist to help him find the "weapon". After making a pact, Yono went to Yamanouchi where he easily took care of Kim, Rufus, and Master Sensei, turing them to stone. When Hana beat Monkey Fist, everyone was returned to normal and Monkey Fist was turned to stone himself and sucked into the earth as he followed the "Path of the Yono". The Yono never appeared again and his whereabouts/fate is unknown.
