JooSang Yoo
JooSang Yoo, known as "Zombie Jr.," competes in the UFC's Featherweight division carrying a professional record of 9-1-0. Across two tracked UFC bouts he has landed 37 significant strikes and recorded one knockdown, suggesting a striker capable of finishing fights on the feet — a reputation reinforced by his nickname's nod to Korean MMA's knockout culture.
Yoo announced himself in the UFC with a KO/TKO victory over Jeka Saragih at UFC 316 in June 2025, then suffered his first professional loss by KO/TKO against Daniel Santos at UFC 320 in October 2025. The back-to-back stoppages in both directions paint a picture of an aggressive, high-risk featherweight still finding his footing at the sport's highest level. With a 9-1 record overall, Yoo brings a winning pedigree into the UFC even as he processes that first setback.
