My Hero Academia‘s latest chapters have been teasing the reveal of Izuku Midoriya’s new full-fledged One For All powers, following the series’ pivotal time-skip. Izuku unlocked the full power of One For All by finally communing with all its previous users – a change that caused Izuku to leave U.A. for good, and start his career as a hero. Deku had to jump into battle against none other than Muscular, his old League of Villains foe from the summer training camp arc. In My Hero Academia Chapter 308, we get to see Deku using One For All’s full potential – including the epic tease of what his new Smash attack is all about!
