I was there and can attest to it being more powerful than anything else in the ring. Honestly, I was hoping for more of an SRL death match, but Blendo was about as close as you could get that day and they didn't even compete. You know you're about to have fun when you have to crank it with a drill just to get going.
I didn't hear about Robot Wars until 1996 (when I hastily put together a robot for Robots Wars III). What a fun and cool time when it was still "punk".
RIP, Marc.
