In the post-credits sequence for X-Men: Apocalypse, fans are teased about the exciting arrival of Mister Sinister to the X-Men movie franchise... but what you probably don't know is that we almost got something completely different instead. Not only does it turn that there were early ideas to make the tag a tease for Deadpool 2, but they actually shot a sequence featuring a new character for the sequel in a special costume.
This fascinating bit of trivia has been revealed by director Bryan Singer and producer/writer Simon Kinberg on the audio commentary for X-Men: Apocalypse, which was just given its digital release this past Friday. As the Mister Sinister-themed clip begins to play at the very, very end of the film's runtime, Singer and Kinberg begin to talk about what could have been, and it's then that the director drops the bombshell:
We did a tag that we really couldn't do -- which I can stick on the DVD. It would have been for Deadpool, and unfortunately it wouldn't have had the right costume for the character they're going to add to Deadpool . I don't want to give that away.
Given that this unused tag scene isn't available with all of the other deleted scenes now available with X-Men: Apocalypse's digital release, it doesn't look like Bryan Singer did "stick [it] on the DVD," as he put it -- which is definitely sad given that we are now ridiculously curious about the character who is being referred to by the director (not to mention questions like "who played the character?" and "what did the costume actually look like?"). Let's consider some possibilities, shall we?
Cable is our number one guess for whom Bryan Singer is referring to here -- mostly because he is thus far the only new character who has been confirmed to be appearing in the untitled Deadpool 2 so far (information revealed in the post-credits scene of director Tim Miller's movie earlier this year). That being said, the fact that Singer doesn't want to give the identity of the hero or villain away could suggest that it wasn't going to be at the very least the first hint at the one-eyed, bionic-armed, big gun-loving time-traveling mutant from the future -- given that Cable isn't a name he would really have to protect at this stage in the game.
The second big possibility is that the final scene of X-Men: Apocalypse was going to introduce the fan-favorite lucky mutant known as Domino. A rumor popped up this summer saying that the character would have a significant role in Deadpool 2, with actress Mackenzie Davis eyed for the part, and it's possible that Bryan Singer wanted to give us a look at her before her expanded role on the big screen. What's holding this theory back is that Domino isn't even confirmed for Deadpool 2 yet, so it's possible that this guess is a complete miss.
Our final guess is a character that X-Men: Apocalypse itself introduced: Olivia Munn's Psylocke. Not only does the purple-loving telekinetic telepath have a history in the comics with Deadpool (fighting together as members of X-Force), but Cable's aforementioned time-travel habits make it very easy to explain how the character from 1983 could co-exist in the Merc With The Mouth's modern world (minus 30-plus years' worth of makeup, that is) and be in Deadpool 2. As far as I see it, the only thing working against this idea is the comment about the costume -- as any director would be a fool to think about altering Munn's completely comic book accurate outfit from Apocalypse.
