Grenadier Bracers

The Grenadier Bracers (籠手) are weapons used by Katsuki Bakugo.

Description
This is a specification that was added to Katsuki's Hero Costume, which stores his sweat to amplify the power and effects of Explosion to their fullest potential. Once filled, he can pull out the grenade pin to release a massive powerful explosion. The aforementioned blast was powerful enough to nearly destroy the building Katsuki was fighting Izuku in during the Battle Trial. This modification was created so that Katsuki could release powerful explosions while minimizing damage to himself.

During the End of Term Test, Katsuki allowed Izuku to use one of the gauntlets to blast All Might. Izuku commented that the strong recoil took a toll on his shoulder, although Katsuki seems to be completely unphased by it due to his superior athletic ability.
