Roaring Aura Sky Ripping Fist

Whirlwind Water Stream: Roaring Aura Sky Ripping Fist (旋風流水 轟気空裂拳, Senpū Ryūsui: Gōki Kūretsu-ken; Viz: Whirling Wind Flowing Water: Fist of Roaring Qi, Rending Air), is a powerful martial art fighting style that combines Water Stream Rock Smashing Fist and Whirlwind Iron Cutting Fist together.

Overview
This technique normally requires two combatants to be performed. To utilize the technique in pairs, Bang and Bomb stand side-by-side and assume strong stances. Both proceed to perform their respective martial arts and strike their opponent simultaneously, sending intense shockwaves through their body and destroying them from inside. Depending on the strength of its users, the shockwaves unleashed are powerful enough to turn even debris into powder within vicinity. The technique was powerful enough to knock back a charging Elder Centipede and even shatter the giant centipede's durable carapace. However, it is stated by Bang that they can only do this technique once per battle since both of them have passed their prime.

During the fight between an evolved Garou and Bang, the Hero Hunter has demonstrated enough skills to not only be able to utilize the technique alone, but Garou's capacities for it are also highly potent, which Bomb even remarks that if Bang takes a direct hit from Garou, the shockwaves will course through his body and break every of his bones into pieces. As Bang and Bomb, even together, are only barely able to perform Roaring Aura Sky Ripping Fist, Bang has wondered if monsterization is what allows Garou to use this devastating technique. Despite one of Garou's blows only grazing Bang's chest, the shockwaves from his blow are powerful enough to seemingly wreck Bang's body, causing his former master to finally fall defeated after a tough fight.
