User blog comment:CrashBash/Crash's Top 5 potential Series 5 heat winners/@comment-5801603-20170617105248

I reckon Supernova would be high up on the list. If it beat Behemoth it could've beaten any other robot in its heat, same with Spawn Again in series 6 too. Not too sure about the others though, but working full pelt it would've stood a god chance against Ironside3.

Fluffy of course, as it had beaten Stinger in series 6 until it somehow came backt to life, and the spinning bar is lower than 13Black's discs I believe.

I'd say the Alien was pretty unfortunate to never at least make a heat final too, but I struggle to see what heats it would win.

Hydra was pretty excellent in series 7 though, shame it was targeted by Gravity as it really impressed me.
