Batman and Two-Face are in trouble!!
So new protege Duke rides in to help:
Perhaps Duke can explain?
Of course, given the difficulty of superheroes trademarking their own names (as likely that would mean having to reveal their own identities, or having a stand-in do it for them, putting their lives in jeopardy), Bruce probably couldn't sue. Then again, maybe Bruce *did* trademark the bat symbol and the rest during Batman Incorporated...? And of course Booster Gold did, so...
This probably means that pretty much every DC city of punk/metal/folk bands based upon/mocking heroes, right?
"Batman's @^$&^"? Hrm...
