R2-D2

Only the most BAD-ASS kicker robot in history of 'a long-long time ago, in a far-far away place'. Though made out of used trash can and looks like a trash can, R2-D2 survived the whole saga like a mechanical cockroach, in a good and BAD-ASS way. The complete opposite of C-3P0's pussy attitude but they're good friends... And hey, R2 will even repair your X-Wing in combat.
