Yeah Deadpool can work in the MCU, he's also the only character that can acknowledge the FOX buy out and stuff. Really all you need to do is have him meet up with the Avengers in a 4 post credits scene walking in and going "OH MY GOD DID DISNEY FINALLY BUY FOX?!?!"

*pounds gavel* SOLD. :lolol

Edit: Is there a limit of words you can do in a post? The site won't let me add a [/spoiler] at the end of my long ass post about Deadpool 2

Here's a little bit of trivia for y'all.
Josh Brolin, the actor that plays Cable and Thanos, is the third actor to play two Marvel characters. The other two being Chris Evans (Human Torch and Captain America) and Ryan Reynolds (Hannibal Cain and Deadpool).

Micheal B Jordan isn't listed here because? He did Human Torch and Kilmonger

Does Kenneth Choi count? The man played Jim Morita in First Avenger and his grandkid Principal Morita in Spider-Man Homecoming.
There is also Benedict Cumberbatch who played Dr. Strange and Dormammu.

Wait, he's the second Human Torch? I didn't know that.
And I never knew about this person. Also, that spoiler part, didn't catch that one. And I even sat through the credits. Must have slipped past me.

LMAO the guy behind the Dragon Ball Super manga got caught tracing Captain America artwork

Toyotarō has been known to trace before in his work. I'm not surprise.

Dang that is subtle.
