So far, it seems as if there is nothing but perks when it comes to Bakugo’s quirk, but there are some downsides to it. In the right situation, Explosion can be a double edged sword, which is why he takes certain careful precautions. For instance, the force of Bakugo’s explosions have a kickback. If an explosion is too intense, it can cause his arms to ache and, in extreme scenarios, even injure them. This is part of the reason he uses his special gauntlets, which allow him to create big blasts without severely damaging himself.
Another weakness of Bakugo’s quirk is temperature. The lower the temperature, the longer it takes for Bakugo’s sweat to fully ignite. This makes him less than an ideal pick for encounters in cold environments. Finally, Bakugo’s most pressing weakness is that his quirk only works from his hands. Take them out of the equation, and he’s incapable of igniting his sweat.
As far as weaknesses go, however, all of these are relatively minor in the sense that he can work around all them in some way. His weaknesses are a far cry from Deku’s quirk, which routinely destroyed his body before he received proper training. Considering this, it’s no wonder why Bakugo excels at being a hero. His quirk is unbelievably versatile, with very few drawbacks, and a high damage potential. Truly, it’s a quirk worthy of his aspirations to become the #1 hero.
