The most bad ass mutha fuckin Jedi Masta, Not master, cuz as we all know Yoda is a tru gangsta. He lives up in the Degoba system and he's under 3 feet tall and can bust yo ass in a blink of an eye.
Yoda was the wisest and most powerfulJedi Master in the history of the order. He got owned by Palpatine though, and had to exile his sorry green posterior to Dagobah.
