I thought Singed was Bane, Pantheon. Captain America wouldn't break someone's back, now, would he? I think he's just shoot their face off.

The Champion to match Batman would have to have:
Superior analytical and deductive capacities
A vengeful drive to put an end to criminal activities
A refusal to kill
Above average fighting capability.
Varus is willing to kill, so he can't be Batman, as that is one of the MOST essential traits that the caped crusader possesses.
