Flash Bang Sweat's name is Conjectural. No official name has been given, and it is subject to change at any time.
Flash Bang Sweat allows Dadan to sweat a substance that produces a bright light and a sound on impact.
Dadan Tadan's hero costume can launch missiles that are filled with his Quirk. Romero Fujimi commented that this Quirk would be better if it could hurt people. It's unknown if this Quirk is the reason Dadan sweats all the time. Using his costume's missiles, Dadan is able to fire a salvo over a wide area, producing a sound loud enough to be heard by those far away from the impact.
- Flash Bang Sweat is similar to Katsuki Bakugo's Explosion Quirk, as both Quirks utilize sweat to fuel an explosion of some kind.
