It isn't known when, how or why Deadpool eventually crosses over with the X-Men franchise, or where it hits in the timeline of that series. But if Colossus' participation in the movie wasn't a big enough tip off, the latest cast photos sure are. Brianna Hildebrand is seen as Negasonic Teenage Warhead wearing a traditional yellow and blue X-Men uniform in these latest images, teasing a Mutant crossover. This latest sneak peek also gives us a first look at Morena Baccarin as Copycat, Ed Skrein as Ajax, Gina Carano as Angel Dust and T.J. Miller as Weasel.

As you may know by now, Deadpool will be showing up at Comic-Con. This morning, after Ryan Reynolds showed everyone that The Merc with The Mouth was having to hitch a ride to San Diego, the rest of the cast of the upcoming film from 20th Century Fox announced their appearance with a nod to The Merc's favorite TV Show, The Golden Girls, by tweeting the theme song. Below, we've lined up all the tweets from the cast in order.

Based upon Marvel Comics' most unconventional anti-hero, Deadpool tells the origin story of former Special Forces operative turned mercenary Wade Wilson, who after being subjected to a rogue experiment that leaves him with accelerated healing powers, adopts the alter ego Deadpool. Armed with his new abilities and a dark, twisted sense of humor, Deadpool hunts down the man who nearly destroyed his life. The 20th Century Fox Comic-Con panel will take place from 5:45 PM to 7:30 PM in Hall H on Saturday, July 11, with Deadpool being accompanied by X-Men: Apocalypse. It isn't known what other movies will be represented, but we might expect to see Channing Tatum appear in support of Gambit as well. Take a look at the Deadpool cast as they prepare for a truly epic Comic-Con 2015!
