It’s Psylocke vs. Deadpool! Olivia Munn already said her character in X-Men: Apocalypse would beat Wolverine in a match-up, but it seems like she’d also best the merc with the mouth.

In a new video posted to her Instagram account, Munn showed off her ambidextrous sword skills in front of Ryan Reynolds before striking a fierce pose. To his dismay, the Deadpool star learned a valuable lesson: never bring a balloon weapon to a katana fight.

Both actors are making their debut in Fox’s X-Men cinematic universe of films. This month will see Reynolds headlining Deadpool when the film opens this Friday, while Munn will unveil her Psylocke skills inApocalypse, out May 27.

During a recent Twitter Q&A, Munn detailed her exhaustive training regime before filming a fight scene over the course of two weeks. “I worked for many months training and I did, like, 6-7 hours a day of sword and taekwondo training, and stunt training and wire training,”she said.
