Binned: Destruct-A-Bubble. At least Medusa was a decent wedge and had an OK looking spinner. Destruct-A-Bubble is a great design, but not a good fighter unfortunately.

Saved: Inverterbrat. The most competent of the remaining bots, I think we can write off what happened in its melee as unfortunate.
