|— Bang prepares to fight Garou.|
After Garou arrives on the surface of Z-City following an extreme physical transformation, he immediately confronts and duels Bomb, who calls out to Bang. Bomb fights with Garou in order to buy time, but is overcome by his brother's former disciple and defeated. Just as Bomb is brought down, Bang arrives.
Bang comments on Garou's sorry appearance in his monsterized state and asserts that he will take Garou down with his own hands. Pledging to go all out one last time, Bang beckons Garou forward, and they clash while Bomb looks on. Bang's Water Stream Rock Smashing Fist and Garou's are completely on par, with master and disciple alike dodging and reflecting every blow. Bang, who used his Awakening Breath technique at the start of the fight, notices that Garou has copied it as well with only a glance. Bang manages to kick Garou away and immediately rushes towards him, proceeding to send him into the air with a tackle. As Bang quickly jumps up and is about to land a powerful blow on Garou, the Hero Hunter counters him by deflecting the blow and sending him straight into the ground, causing a bleeding on Bang's head.
Realizing just how much more skilled of a fighter Garou has become since his days as a disciple, Bang backhandedly tells Garou that he is more worth teaching now than ever before. Garou merely growls and the two continue to fight.
Garou and Bang simultaneously land a hit on each other that knocks both of them back. Garou then takes the stance of Explosion Release Fist, which surprises Bang and Bomb as that is the martial art style Bang primarily used before developing his Water Stream Rock Smashing Fist. Utilizing his new fighting style, Garou proves able to overwhelm his former master and pushes him back, significantly wounding him. Bang refuses to give up, rushing towards Garou and continuing the fight.
- During this fight, Bang believes himself to be a failure as a master and decides to quit being a hero.
