Jack Strife, the Pumpkin King is the servant of the Necromantress. He put a curse on the Cauldron Sisters' cauldron, Myx, but by defeating him, the hero was able to lift the curse. He commands some Pumpkin Pis. Even through he wasn't "Pumpkin Prince" the previous year, and not even noble or of royal blood, and he didn't have even a kingdom, but he still got his title, just by making himself "Pumpkin King".
