Odan-Urr

Odan Urr was famed throughout the galaxy mainly because he was a total smarty-pant and he created the infamous Great Jedi Library. Apart from that, he recovered a sweet, pyramidal sith holocron that was bright red, and little did he know that little block full of sith knowledge would lead to his miserable death. However, other than that, not much is known about Urr except for the fact that he was one ugly-ass mother fucker.

I mean, just look at the guy! He's some purple slug-like crustacean with the body of a human. Sure, some people like Nien "Nonk" Nunb and Plo Koon are sure ugly with their frilly faces and wrinkly tusk/horn things, but this guy tops all of them. He's like a raisin with arms, legs, and one big ass brain. And not only that, the animal rights activists of the universe also made it legal for weird organisms like Urr to possess lightsabers, so guess who has one. That's right, Urr does! Just when you thought giving animals guns and knives was bad, the damn activists give them lightsabers and force powers.
