Pumpkinator

The Pumpkinator is the archnemesis of Crash Nebula. A real version of the Pumpkinator appeared in Scary Godparents, after Timmy Turner's wish turned the popular kids' Jack-O-Bot costumes into real space suits, and they merged together to form this entity.

Character
The Pumpkinator is an evil villain that destroys planets by growing vines which dig into the surface of the planet, and then causing a countdown. When the countdown reaches zero, the Pumpkinator explodes, the planet going along with it. In the television special that Timmy was watching, the Pumkinator splits back into the Jack-O-Bots after it destroys the pumpkin shaped planet it was on.

Description
The Pumpkinator is similar in shape to the Jack-O-Bots, it is shaped like a jack-o'-lantern with arms and legs. It also wears a horned helmet on it's head, and has vine appendages which dig into the surface of the planet while it is counting down to explode. A countdown timer appears out of it's helmet when it is about to destroy itself and the planet its on.

Background
When Timmy wished that everyone's Halloween costumes would become real and scary, everyone become real and scary versions of the costumes they were wearing. The popular kids (Tad, Chad, Trixie and Veronica) had been wearing authentic Jack-O-Bot costumes, and were turned into actual Jack-O-Bots. When all four of the Jack-O-Bots merged together, the Pumpkinator was created. It planned to transform into a giant doomsday device that would destroy the Earth. After four minutes, it transformed and started counting down from 59 seconds. Just before the timer ran out, Timmy unwished the wish and the Pumpkinator was turned back into the popular kids in costumes, who fell together into a harmless pile.
