Stun Grenade (閃光弾 (スタングレネード) Sutan Gurenēdo?) is a Super Move performed by Katsuki Bakugo using his Explosion Quirk.


Katsuki creates a sphere of light between his hands that explodes into a large scale flash. Similarly to the effect of an actual stun grenade, the flash of light blinds anyone close by.

It is especially effective against Quirks that are weak against light, such as Fumikage Tokoyami's Dark Shadow. Katsuki first uses this move to overpower Fumikage during the U.A. Sports Festival.[1] He also used it during the First Term Final Exam against All Might [2], and then again during his fight with Izuku [3].


  • Zero Distance Stun Grenade (ゼロ (きょ) () 閃光弾 (スタングレネード) Zero Kyori Sutan Gurenēdo?): A variation where Katsuki fires off his Stun Grenade at point blank range of the opponent to immediately stun and immobilizes them with little lasting damage.[4] This variation was first used against Setsuna in the fourth round of the Joint Training Battle.


  • The animation for using Stun Grenade bares a striking resemblance to the Final Flash attack from the Dragon Ball series.
