Deadpool would defeat Batman in a fight.

"Bruce Wayne is in the top fighter of DC. Training for years on end, he has perfected his own style and often changes his style around to be less predictable."While that may be true, Batman is nowhere near as unpredictable as Deadpool in terms of not only martial arts combat, but also psychologically. Similarly like how Bruce is unable to predict Joker after years of extensive research, Taskmaster, who has the ability to replicate movements and techniques of various heroes like Daredevil, Spider-Man, and Captain America, has failed to defeat and properly assess Deadpool's movements to this day. Unlike Batman, Deadpool can literally dance and fight simultaneously. http://img208.imageshack.us..."As Batman, he has beaten David Cain, Lady Shiva, and possibly Cassandra Cain. The latter three recognised as the top fghters. The common factor between them: they are all better fighters than anything Deadpool's faced."While the first sentence is true (for the most part), the second part isn't. David Cain does not have enough showings to suggest he is any better than the likes of Captain America, Daredevil, Iron Fist, or even Taskmaster. His best showings are beating up a pregnant Shiva, skirmishing for Deathstroke for a short period of time, and holding his own against Batman before losing. I'm pretty sure even Cassie as a young child was able to beat him. Lady Shiva is impressive but Batman has only beaten her off-panel as far as I'm aware, when he told Batgirl that "even he had beaten Shiva." There's one moment where Batman easily beats Lady Shiva in SUPERMAN/BATMAN, but Grodd was mind-controlling her, and it is shrugged off as bad writing. Hardly a reliable instance. As far as I'm aware, Batman has only been able to fight Shiva evenly, and only won because Robin interfered. The same goes for Cassandra Cain. Batman only beat her once as a child, and when she lost her body-reading. After giving Cassie a CD with 127 martial arts techniques, I believe she regained her body-reading abilities and had no problem utterly dismantling The Dark Knight with relative ease. Deadpool is perfectly capable of doing the same. Cain doesn't have enough backing to be that impressive, and Shiva's martial arts skill alone isn't enough to take down Deadpool anyways. Cassie is the only one here I see being able to defeat Deadpool, but even then her gadgets are non-lethal like Bruce's. That, and Joker's psychotic behavior and erratic body language allowed him to land a few hits on Batgirl, so I don't see why Deadpool, who is arguably as crazy, wouldn't be able to do the same with his katana. In fact, your "better fighters" statement is wrong. Captain America would beat Cain without too many problems, while guys like Daredevil, Iron Fist, and Taskmaster could at least hold their own against Shiva and Cassandra, especially considering Taskmaster's photographic memory, Matt's radar sense, and Danny's chi abilities. Deadpool has faced off against more impressive enemies. "They have all studied/mastered all major martial arts known to man (Batman even knowing Kryptonian and possibly Tamaranain martial arts). They regularly take on 20 guys at once, not getting hit."This is more flashy than efficient. Kryptonian and Tamaranain martial arts sounds good, but they haven't shown efficiency outside of some scarce pressure point showings. Nonetheless, Batman doesn't, at least consistently, incorporate those fighting styles in battles anyways. Deadpool on the other hand, has enhanced strength, doesn't experience fatigue due to his healing factor, and unpredictability on his side. Taking out twenty generic thugs is dandy, but Deadpool has fought an entire army by himself and was unscratched. Now it is important to note that Deadpool has an indestuctible face due to a curse on Loki, it doesn't effect the fight much. He still wrecks the entire army, and it's not like the guys can't shoot his chest or neck.http://static.comicvine.com...http://static.comicvine.com...http://static.comicvine.com...http://static.comicvine.com...http://static.comicvine.com..."Batman has regularly been benching 1000lbs., but much more impressive is his striking power. As Bruce Wayne he kicks down trees and steel doors. As Batman, several versions have him regularly injecting lead into his gloves. He has been shown to hurt Killer-Croc and Bane." Impressive indeed. However, it's not nearly enough to knock out Deadpool. On the low chance that Batman does inject lead into his gloves, in which he has not displayed to do consistently against tough and durable opponents Pre or Post-Flashpoint, hurting Killer Croc and Bane still isn't good enough. In fact, Bane has been able to fight Croc before, and Croc is notorious for being an absolute joke in comic books. The guy never wins against anyone. Bane on the other hand, even on Venom, is not in the league of Deadpool's durability. We're talking about someone who has healed from a nuclear bomb. Rhino is far more physically capable and durable than both Bane and Croc, and his toughest punches do send Wade flying, but no damage is inflicted on the Merc with a Mouth. Is Batman's strength, even with the lead-injected gloves, on the level of Rhino, who is confirmed by multiple sources to possess 70-100 ton strength? No. http://static.comicvine.com...http://static.comicvine.com...http://static.comicvine.com..."Batman wears armor that has allowed him to survive much more than you or I could handle. The Batsuit is bullet resistant (bullet-proof, depending on the distance)." Deadpool's healing factor allows him to survive much more than Batman by a wide, wide margin. Bruce is tough, but he's only human. Bullet-proof armor is a noble effort, but against constant bombardment of grenades, mech-cutting katanas, and the other countless lethal equipment, it isn't going to hold up for long. There's a reason why Batman bothers to dodge bullets in the first place. Also, Batman has a gaping, exposed spot in his mouth/chin area. I vaguely remember Batman having an clear shield he can bring up in that area so that he doesn't get shot, and he used it once against some thugs, but again, it isn't consistent and is a one-hit wonder gadget. Regardless, it isn't standing up to Wade's katanas. http://static.comicvine.com..."Batman has dealt with members of the Court of Owls, each having a healing factor. While they were not as good at healing as Deadpool, they still had the healing factor. Batman despatched several members before retreating back into the bat-cave and coming back with his Bat-tle Suit and anti-healing temperature."There is more than meets the eye. You are right, the Talons' healing factors were nowhere near as powerful as Deadpool's. However, they were also not very skilled save for a few notable ones, and were beaten up by Bruce in nothing but his robes. That may be just good skill on Batman's part, but considering Cobb was able to put up a fight, it speaks that the no-name Talons weren't of high quality. Another thing is that Batman had already analyzed the Talons extensively and kenw their weakness to the cold after he captured William Cobb, and found out that he was Nightwing's grandfather (or something along those lines). The point is, Batman knew who and what he was dealing with, and had the benefit of being in his own domain, the Wayne Manor. He doesn't have any of those benefits here, and Deadpool is significantly more skilled and durable than even the best of the Talons. Batman will underestimate his opponent and will not live to tell the tale.
