Cross Fang Dragon Slayer Fist

This secret joint technique that even a world-class genius cannot normally perform alone, Cross Fang Dragon Slayer Fist, was acquired by him subconsciously.

Whirlwind Water Stream Cross Fang Dragon Slayer Fist (旋風流水 交牙竜殺拳, Senpū Ryūsui: Kōga Ryūsatsu-ken, Viz: Whirling Wind Flowing Water, Fist of Biting Fangs, Killing Dragons), often simply referred to as Cross Fang Dragon Slayer Fist (交牙竜殺拳, Kōga Ryūsatsu-ken), is an extremely powerful martial arts fighting style or technique that combines Water Stream Rock Smashing Fist and Whirlwind Iron Cutting Fist.

Overview
As Cross Fang Dragon Slayer Fist is a combination of the martial arts of both Bang and Bomb, it is very powerful and seems to possess the properties of both Water Stream Rock Smashing Fist and Whirlwind Iron Cutting Fist. When using the technique, Bang and Bomb rush towards their opponents and unleash a series of extremely powerful strikes on them with their respective martial arts simultaneously. Although this technique is more powerful than even Whirlwind Water Stream Roaring Aura Sky Ripping Fist, which was already strong enough to completely shatter Elder Centipede's super-powerful carapace, Overgrown Rover, even when weakened and wounded by Saitama prior, was capable of withstanding the technique from Bang and Bomb while sustaining little to no effect whatsoever, only being knocked away momentarily by them. This technique normally requires more than one fighter to be performed, as seen in the case of Bang and Bomb. However; Garou has subconsciously attained it through talent, capable of single handedly performing the technique by using Water Stream Rock Smashing Fist in his left hand and Whirlwind Iron Cutting Fist in the right. During his fight with Garou, it is noted by Superalloy Darkshine that when Garou utilized the technique in an attempt to break through his defense, he felt like dozens of martial artists were focusing their attacks on him as the Hero Hunter continued to grow faster and stronger throughout their battle.
