Here's a couple that stand out to me, both of which are from Crossroads regional:

-2481's fall from the top of the pyramid during the semifinals in 2013. I didn't see the details but the damage was so severe that despite the efforts of all involved and the alliance's timeout coupon the robot couldn't be restored to full functionality (it was limited to defense). It was a nasty fall; getting the robot driving was an achievement in itself IMHO.

-The winning #2 alliance in 2014. That poor alliance had some lousy luck with robot breakage (and still won no less). Due to 5188's failure in Q3-1, bye-bye went their timeout coupon. In Q3-2, 5188 broke down again, and the backup coupon also went bye-bye. The bad luck subsided until finals match 1, when 1108, the alliance captain, had (IIRC) some LED light wire pinch, short, and melt away (the insulation at least), taking out a large chunk of their wiring. below said wire. They still won the match. Due to the extensive damage, and despite the opposing #1 alliance graciously calling their timeout on 1108's behalf, they spent match 2 in the goalie zone, paralyzed. However, after a pit run during the match and fast hard work between the matches, they got it running minus the catapult and went on to win the match and the regional (and a load of other awards). I honestly don't think I've ever seen such an impressive comeback.
