We'll have to wait a bit longer to see the X-Men design for Avengers: Doomsday, because it turns out that a previously 'leaked' image is just fanart.
The original artwork was shared by Alan Cumming himself, who plays Nightcrawler and is returning for the next Avengers movie. It appeared to show a picture of his character in costume, but, as one person has debunked on Twitter, the image is actually an edit made by a fan and shared online last year.
