Umbok is a Lutabot demolitions expert whom no Foldabot would want to mess with,especially in close range battle.His lethal horns can charge through the toughest defense barriers and smash into thick ice.When there's nothing to pummel, Umbok is used more for intimidation than as a warrior due to his poor intellect and slow speed Umbok's main flaw is his lack of initiative- he waits to be given orders before he makes a move. He appears in the October 2010 K-Zone issue.
