Always loved Ki-Adi-Mundi. 8 out of 10 times on the internet, if you see a post from Ki Adi Mundi, it's usually me lol. He's the ugly duckling of the Jedi. Huge friggin dome. Plus, he has a fumanchu beard.
I would also have to say I really dig Qui-Gon. It sucked so hard he died in Episode I. He struck me as what I thought a Jedi should be like.
