Deadpool 2 introduced several members of X-Force... before killing most of them off in one of the sequel's funniest sequences.
Zeitgeist, Bedlam, Shatterstar, Vanisher and poor ol' Peter all met their makers in various gruesome/hilarious ways, and even though The Merc with a Mouth (Ryan Reynolds) did go back in time to save his "Sugar Bear" in the mid-credits scene, it was generally assumed that the others were going to be one-hit wonders.
Lewis Tan, who played alien swordsman Shatterstar, has previously indicated that Wade actually prevented the entire team's demise with Cable's time machine, and was confident that he would be a part of the now defunct X-Force movie.
"You’re going to see more of my character in the X-Force film... that's what it's looking like," he told SyFy Wire back in 2018. "Thankfully, Deadpool went back and had a little time machine that he stole, so in the post-credits scene he brought back Peter, and it’s assumed that we’re all going to come back as well."
Now, the Mortal Kombat actor has sent out a Tweet which appears to be teasing his return for Deadpool 3.
Of course, there's a chance this is simply wishful thinking on Tan's part, but if Domino (Zazie Beetz) and Cable (Josh Brolin) are set to return (rumored, not confirmed), then there's nothing to suggest we won't see the rest of Deadpool 2's supporting players - even if it's just for a scene or two.
