If Reynolds does show up in either "Doomsday" or "Secret Wars," it could be the last time fans see Deadpool for a while. A recent report from Variety claimed that Marvel sees projects like "Deadpool 4" and "Blade" as low priorities.

Marvel announced the mega cast for Doomsday back in March with Robert Downey Jr.’s return confirmed last year, as he leaves behind Iron Man for Doctor Doom. But while fans might want Deadpool in the ensemble films, Reynolds did previously say that if it were to happen, it would mean the end.
