voiced by: Frank Welker
During most of the show, Nibbler masquerades as a cute, innocent and unintelligent pet but in some circumstances, he breaks his undercover identity and we suddenly find out that he is super-intelligent and is equipped with strange abilities, which he uses as part of his secret mission to preserve the existence of the universe.
Nibbler is highly intelligent and capable of communication, but mostly he uses telepathic manipulation to simulate human speech. Sometimes he reveals his secret mission but then immediately wipes their memory of it afterwards. His eye is also able to fire a heat ray and he has the ability to belch up unwanted portions of anything he ingests, such as antlers, ham bones, anything.
