Deadpool is the definition of cool, so much so that even Ryan Reynolds couldn't kill him.
There is something about a hyper self-aware superhero that makes Deadpool stand out from the rest of his peers. There is a reason that he is almost always found in the top three of any
superhero list, no matter if that list is covering movies, comic books, or lunchboxes — Deadpool is always the answer.
It doesn't hurt that he is also a badass character in the series. His patented ability to break the fourth wall somehow still works despite all the insane action happening on the screen. He also has an ultimate move where he literally grabs his health bat and uses it as a weapon. I can't even handle how cool that is as a concept.
