Goddard

Goddard is the robotic canine pet of Jimmy Neutron. He has multiple functions such as flight and self destruction. He has made apearences in the crossover television special, the Jimmy-Timmy Power Hour and the video game Nicktoons Unite!. He is voiced by Frank Welker who also voiced Vicky's dog Doidle.

Jimmy-Timmy Power Hour
In the first special, Goddard is in the middle of a routine tune up when Timmy Turner magically poofed into Jimmy's lab and mistook Goddard for a video game system. Timmy downloaded a copy of Decimator into his hard drive and left the lab. Not long after, Goddard transformed into a monster and began attacking the city of Retroville. Attempting to stop him, Timmy was eaten by Goddard and trapped in an area of Goddard's structure that was filled with dangerous acid, presumably a stomach like chamber. Timmy used one of Jimmy's laser pens to crawl through a vent and find Godard's hard drive where he removed the game and allowed Goddard to return to his original programming. During these events, Jimmy had invented a transporting device out of Timmy's magical Auto-Poofer which was stolen by Denzel Crocker to reach Fairy World. Assuming the Fairies to be computer programs, Jimmy was willing to let Crocker take control but Timmy convinced Jimmy that although they aren't "real", Timmy loves them the same way that Jimmy loves Goddard despite being a robot. This inspiration helped Jimmy save Fairy World and all magic. At the end of the special, Timmy is left at his school science fair without a project an in return for his help, Jimmy perfects the teleportation device and sends Goddard to Dimmsdale as Timmy's entrant.
