Wade Winston Wilson a.k.a (Deadpool) is known to be one of the most popular anti-heroes in the Marvel universe. But is he the strongest? Deadpool first appeared in the Marvel universe as a villain in a issue of "The New Mutants" and later appeared in "X-Force". "Deadpool Kills the Marvel Universe" was a comic that had a storyline of Deadpool killing the Marvel universe including his creators.
Deadpool has the ability to heal from anything and is able to teleport from anywhere, at any time with the use of his teleportation belt. It is pretty much impossible to kill Deadpool, but their are many characters other than Deadpool for example Dr Strange, Galactus, Thanos and many more that are way stronger than him. But Stan Lee has once tweeted saying that he thinks that Galactus is "probably" the strongest Marvel Superhero.
