5-17 years of age (14,006 in human years)
Nibbler is a respected Lord on, and Ambassador for his home planet of Eternium. He is disguised as a dumb pet to guard against imminent attacks by the flying brains who are his arch enemies. Lord Nibbler’s race has been around since time immemorial and they are highly intelligent apart from being very cute. Nibbler was rescued by Leela when Vergon 6 was about to implode. Nibbler is a voracious eater who can devour large animals whole. Nibbler’s excrement or dark matter is used as starship fuel and once filled the core of Vergon 6 before a Democratic Order of Planets (DOOP) mining crew mined the planet hollow.

This character's true name is not revealed, because "in the time it would take to pronounce one letter of his true name, a trillion cosmoses would flare into existence and sink into eternal night".
-Nibbler: I didn't travel back in time! My people lack that ability.
-Fry: But... I know you in the future! I clean your poop!
-Nibbler: Quite possible. We live long and are celebrated poopers.
-Leela: So, how was the universe created?
[Nibbler babbles in his native language]
-Leela: And the meaning of existence?
[Nibbler talks some more]
-Leela: So every religion is wrong.
-Fry: [Discussing Fry being his own grandfather as a result of going back in time and getting with his grandmother] I did do the nasty in the past-y.
-Nibbler: Verily. And that past nastification is what shields you from the brains!
