Appearances in Other MediaEdit
Recollection Of A Most Sincere ApprenticeEdit
Bang was wiping the floor, when Charanko entered the empty dojo. When asked where the other students were, he stated they all quit. Bang then tells Charanko he is his only student and noticed that Charnko looks pumped up.
Bang invited Saitama and Genos to his dojo to eat some lobsters he received from his brother Bomb, while Charanko arrived to bring the rest of the ingredients to make hot pot. As they were preparing the meal, Saitama noticed there isn't any cabbage and after some arguing Bang decided to go to the store. When he returned from the store, Bang's dojo was completely ruined after the dojo hunters came and thrashed it, unbeknown to him it was Saitama's and Genos' doing. Bang then immediately blames Benpatsu, the last remaining dojo hunter.
Bang, Genos and King were called by Saitama to be part of his group against Fubuki and her Blizzard Group. Before the competition begins, Saitama signs a contract, stating the losing team must do whatever the winning team wants. Bang decides to go first, believing that the game will be a sparring match, and asserts that the losers must join his dojo. Unfortunately, the game that Fubuki had in mind was actually a video game, thus Bang was easily defeated.
Later Bang arrives in Y-City, where he saves Red Muffler from Jumping Spider. It was revealed that their team won against the Blizzard Group thank to King. Child Emperor was at the scene and took the opportunity to measure the heroes stats with his new device Okame-Chan, but Bang refuses to participate.
Bang, Who Is Too OverbearingEdit
After witnessing Saitama's strength, Bang began spying on him and Genos to better understand his power. Fearing that his martial arts style Water Stream Rock Smashing Fist would end with him, Bang decided to invite them to his dojo. When they didn't arrive. He began secretly following them and coerced Saitama to his dojo in pretense of giving them free meat.
At the dojo, Bang demonstrates his style and challenges Saitama to some card-based memory games and rock-paper-scissors, with Bang winning almost every time. During one rock-paper-scissors match, an enraged Saitama nearly crushes Bang with a hammer, who is then forced to admit that Saitama is truly powerful. He does note, however, that the rock-paper-scissors game was the most excited he had ever seen Saitama be, and offers Saitama to join his dojo, but Saitama refuses. 
The Murder Case That Is Too ImpossibleEdit
Bang and the other S-Class heroes were invited to a hot spring resort, after the Dark Matter Thieves failed invasion. While enjoying himself at the hot spring, Metal Bat wasn't satisfied that some of the heroes that did not participate in the battle were invited to the resort, but Bang managed to calm down the situation. The next day after the ceremony, the heroes find Zombieman murdered, stabbed in the back by Atomic Samurai's katana.
As Child Emperor was investigating the murder, Bang was one of many that were still at the banquet hall and was ruled out as a suspect. While the investigation wasn't progressing, Tatsumaki tried to restrain everyone, until Zombieman suddenly woke up. Zombieman later revealed that Atomic Samurai's katana was floating with green light surrounding it similar to Tatsumaki, when it stabbed him. Zombieman didn't care what happened the night prior and the heroes disbanded.
