Deadpool is far from an idiot.. psycho? yes. Idiot? no. He is actually very smart plus an excellent marksman and amazing with blades and hand to hand combat. He would mostly get his ass kicked by wolverine (Extremely) but lucky him he has that amazing Healing factor so Wolverine would get tired and then Deadpool would eventually win.
Do I see Batman down there? Thank the lord I saw that comic and was like 'WTF too many weird time travel comics!' (please tell me that is batman and I'm not a loser) Oh, and Thor even looks pretty when passed out drunk xD
