One of the most important aspects of comic books are the personality of the character. Whether they like to talk trash during fights, be a little rough in delicate situations or even too nice in times of war, as characters personality really brings more entertainment to every comic book. Easily one of the most charismatic character in the Marvel Universe is Wade Wilson (Deadpool) a character with so much personality that he is aware that he is a comic book (this is known as 4th dimensional awareness). In addition, Deadpool addresses he is in a comic book and even makes fun of the Authors in different comic books. These comments are known as 4th wall breaking and usually Deadpool is the only Comic book hero that can do so. A great example of this is the image above, in a series done in the Alternate Universe Deadpool has his dark side fully unlocked and he goes around taking out all the super heroes and villains in the Marvel Universe. One of his toughest fights was against The X-men's poster boy Wolverine,who has a similar healing factor to Deadpool. Now, this isnt the first time they have fought since Wolverine is pretty tough to take down, however in this fight Deadpool pulls a classic 4th wall break and addresses the fact that Wolverine is too popular to let die. The iconic party of this fight is the fact that Deapool kind of cheats in this fight, usually the only way to kill Wolverine is to cut off his head however that's very difficult to do. In the comic book series Deadpool uses a special sword made out of a metal called Carbonadium, a metal similar to the metal that Wolverine is made of (Adamantium) this metal also takes away a mutants healing factor. With this death blow Wolverine would not be able to come back, not in this universe at least.
