She doesn't dodge. She doesn't block. She stands there, looks you dead in the face, and hits you so hard you forget your name. Meet Ellie Dempster — undefeated Power Slap athlete, 2025 Rookie of the Year, and on July 10th at the Cosmopolitan of Las Vegas, the first woman ever to fight for the Power Slap World Championship. But her story isn't just about slapping. It's about a girl from Canada who moved to Thailand at 19, became a children's TV host, learned Muay Thai to teach orphans how to defend themselves, tore her ACL on stage in front of Joe Rogan and GSP, played rugby for 14 years, raised $115,000 for St. Jude's — and somehow ended up in Dana White's office holding a pair of shoes.
