This is the only clear image of him as of January 2021.
New recent and better detailed image of him.
He's known as the Stop Looking At Me Guy. He appears on a DS, and he doesn't like to be looked at. Cone Head confirmed Hillburg Edgar is smarter than him. He needed him to tell Cone Head where Zombicon is. But this just got him mad, cause Cone Head sounded even dumber. Even if he is smart, doesn't mean he automatically knows where a place is.
It turns out he's Zomboss's son, and is a powerful zombie Crazy Dave never defeated. Crazy Dave keeps a photo of him on a wall as memory he needs to be defeated.
