In a way, yes. Since he has no superpowers, he really is an underdog...
However, he's so...Godlike, as the other thread states...that he has completely overcome it. Batman beats the hell out of everyone he fights, pretty much, including the JLA. So he's, in a way, made the powerhouses the underdogs, cause he's too damn smart for them.
A billionaire playboy that knows 127 martial arts, is head of a superhero team, has never really lost a fight and owns a fleet of Rolls Royces=UnderDog?
Being powerless means nothing when you can make up for it 100 fold by being one of the richest men in the world and owning stockpiles of tech from Gods.
wtf are you kidding me...? superman???? and what the hell is batman money bags gunna do with all this cash...take over the world...? buy a stealth plane which costs $2,000,000,000? even then supes would take him down...batman doesnt use his money to his advantage, except when getting his gadgets and suit, batmobile...and how is that more potent than like 100,000,000,000,000 ton+ strength, heat vision, flight, tornado breath, supersonic hearing, light speed, and invulnerablity???? give me a legitimate answer n i might consider batman not being an underdog,.....
Because, using his enormous wealth, he can duplicate class 100ton strength(Battle suit) Heat vision(plasma blasters)Flight(Jet thrusters)Tornado Breath(Hyper velocity wind generator)SuperSonic hearing(Sound amplification) Light Speed(He can makes something that flies super sonic, LS is impossible) Invulnerability(Uber Kevlar suits).
All this(except for the light speed) he's actually had and used. Batman is everything except an underdog, he's a damn near world power fer christs sake.
oh so batmans just gunna have all this stuff in a little backpack when hes hoppin around on rooftops fightin crime and be able to whip ne one of those things u just named out ne second when he sees a criminal?...rrrrriiiiiiiiiight...and, whens the last time he did something like this..?
Slade is not an underdog, he is one of most skilled, smartest, and feared villians,....Arsenal is an underdog, he is always getting his ass handed to him
