Quoted from Frippertron:How did Marvel get away with the Deadpool character to begin with. He was a ripoff of DC's Deathstroke and to add insult to injury, Deathstroke's name is Slade Wilson and Deadpool's is Wade Wilson. Why didn't DC do anything? It's kind of funny how blatant the ripoff is.
that's kind of deadpools thing, to make fun of the Superhero world.
