Mirio Togata / Lemillion

Mirio Togata is a third-year student at U.A. High School and the most prominent member of the Big 3. His Quirk, Permeation, allows him to phase through any solid matter, making him nearly impossible to hit. Before Izuku Midoriya, Mirio was the top candidate to inherit One For All from All Might. Despite temporarily losing his Quirk after being shot with a Quirk-Destroying bullet by Shin Nemoto during the Shie Hassaikai Raid to protect Eri, he continued fighting through sheer willpower and combat skill. His Quirk was later restored by Eri's Rewind ability.
