Black Jack

Black Jack is a black glump with a spiky piece of hair on the top of his head and ten shiny teeth in his lips. He also has three spots on each of his cheeks.

Bio
Mad, bad and dangerous to know, Black Jack is one mean Glump. Even other Glumps steer clear of this fearsome ball of fury – especially if he’s knocking down the citizens of Monstro City with a Cannonball Cavalcade!

Trivia

 * His name is a pun of actor Jack Black.
