I'd be the retired captain of the old "34th Special Mech Division" that now works as a handicapped mechanic. I'd fix up all the beat-up mecha that the young bucks bring to me, all the while imparting sage knowledge of how their brash natures will eventually get the best of them. Eventually, I'd get attached to a promising young upstart and come out of retirement to show the kid how it's really done, only to die horribly moments later, teaching him a lesson about the meaning of friendship, or some such. *Cue the sad music*
