Cena makes top heels. Almost anyone he feuds with, becomes top heel of the moment. If they're booked to stand a chance against him, that is. If he just dominates, then the heel is screwed.
Nexus wasnt soley focussed on Cena though to be fair , though Cena certainly buried them :sad:Nexus? I don't really remember them getting a whole lotta cheers when they fueded with Cena. Maybe I'm wrong.
