The Question: Now, let's be theoretical for a second and assume that Deadpool does make an appearance in an X-Men movie: will Fox allow his signature brand of meta, fourth-wall-breaking humour to come along as part of the package? The Likely Answer: This is a tough one. On one hand, the humour has been a huge hit in Deadpool's own movie, but will Bryan Singer and co. want that potentially messy, continuity-muddling riffing to interact with their more serious, straight-laced comic book film? Humour is one thing, but if Deadpool's there cracking wise and constantly ribbing the real-life nature of the movie's existence, it might detract from the more somber tone of the core X-Men films. We'll go with no, but then in honesty, it's unlikely that Pool would even get anything more than a cameo in a regular X-Men movie anyway.
