User blog comment:CrashBash/Crash's Top 5 potential Series 5 heat winners/@comment-979907-20170612045320

Interestingly I think Kan Opener could've won its own heat in Series 7, had it not jammed into Barbaric Response. It could also have done strongly in Spawn Agains heat, since it beat the eventual heat winner a few times in the annihilator.

Big Nipper is tough - the series 5 finalists didn't really have a weak link it could defeat, and Series 7 I imagine it could've beaten St Agro but it's so hard to say.

Hydra almost won its own heat in Series 6, so it's a strong contender.

If the above three make the list, I'm still stumped for a 5th, so I'll be interested to see who you get
