Despite its fearsome sounding name, the Happo Daikarin is actually something of a joke. It involves Happosai hurling home-made bombs at a target, engulfing them in explosions. Despite this, they are actually extremely powerful; Happosai has been seen accomplishing feats like knocking out Pantyhose Taro in monster form with just one of these bombs. Happosai occasionally displays the ability to rapidly launch barrages of bombs, hurling them with great speed to cover an area with multiple explosions. He also sometimes uses larger than normal bombs, with correspondingly more powerful explosions.
