Nibbler

Lord Nibbler is one of the two overarching protagonists (alongside Mrs Fry) of the Futurama franchise. He is voiced by Frank Welker.
==Bio==
Nibbler masquerades as an innocent, cute and unintelligent pet during most of the series. In reality, he is highly intelligent and capable of communication, but tries to avoid suspicion while he goes about his mission of protecting the Earth in general and Fry in particular from the evil Brainspawn. Nibbler's feces consist of dark matter (as all of his species do), which can be used as starship fuel. It is an extremely dense material, "each pound of which weighs over ten thousand pounds", according to Professor Farnsworth.
It turns out that his species provides undercover in order to defend the universe from the Brain Spawn, and nobody remembers his actions due to his wiping of their minds afterwards. Until he officially assigned himself to Earth as a part of the Planet Express crew.
