Qui-Gon isn't completely pointless but if he hadn't shown up and found Anakin one of two things would have happened: 1.) Sidious would never had a powerful apprentice to destroy the republic, because of that the clone wars probably wouldnt have started and Sidous wouldnt have tried to take over. And even if the clone wars had taken place, Anakin wouldnt have been there to help kill mace windoo, therefore Sidious dying. Or 2.) Anakin would have been discovered by someone else most likely, fading into the jedi order, and not having to deal with Obi-won's reluctants to teach Anakin, therfore helping him not to tip toward the dark side. Qui-Gon wouldnt die in ether senerio.

Yoda. Definitively Yoda because he's small, green and EPIC!!! "Don't call him your little green friend....."

I'd probably be Yoda because... he's Yoda, need I say more? Darth Sidious: I have waited a long time for this moment, my little green friend. At last the Jedi are no more. Yoda: Not if anything to say about it I have! [Yoda force flings Darth Sidious across the room and across his desk] "Don't call him your little green friend..."

I would bring Yoda to a bar fight because... its Yoda, need I say more? Size matters not. -- Yoda Try not. Do or do not, there is no try. -- Yoda

Star Wars Battlefront 1 and 2 are always amazing. The lego star wars was kinda fun also. The force unleashed and revenge of the sith are a must play.
