@Picard: but even with all her powers and abilities batman would eventually FIND a weakness. its what he DOES. batman doesnt have super strength or speed or agility. he uses his INTELLIGENCE to fight and he uses his parents death as a motivation rather than a thing to dwell on. it fuels him and drives him to overcome anything standing in his way and that's ussually why he wins. i understand buffy is very wise and strong but shes not cut out to kill the goddamn batman. btw both mik mignolas run on batman and the killing joke are both non canon in the dcu. just so you know...
Here is the thing... Batman is mainly fighting masterminds - skinny guys like Joker, Riddler, Mr. Zsasz - or fat, little ones ;) - like Penguin. They can be interesting characters but surely they don't posse great physical threat. Buffy on the other hand is not only stronger, faster and more durable than Batman, she fighting - on a nightly basis - creatures that are both stronger, faster and more durable than Batman. So in h2h fight - withouth prep - Buffy wins. And she don't need a year of preparations, nor the Scythe to do this. You say that he eventually will find her weakness... probably yes. But it is irrelevant to our discussion. "Killing joke" in non canon? So why Barbara Gordon is in a wheelchair? His obsession about parents death... well Ra's Al Ghul - yet another mastermind - used this very effectively against him in "JLA Tower of babel" didn't he? So I think it can be as much source of strength, as well it can be his Achilles heel. Sure, Buffy is not a genius like Batman - never was, never will be - but she also don't possess vast family fortune and unlimited time to study and develop their cognitive skills. Thats all don't change the fact that in straight fight I would bet on Slayer.
@Void_Paladin: Firstly you must prove that nerve strikes would work on her. :) Secoundly this is how Batman is "dealing" with faster, stronger and more durable more durable opponents in open fight: ;)
Azrael was capable of lifting 5-8 tons when this fight occured and he's much more skilled than Buffy.As for Deathstroke,why don't you actually post ALL the scans instead of the out of context ones? Slade was limping away and he got owned by a thug after the fight.
