The Murder Case That Is Too ImpossibleEdit
Metal Bat and other S-Class heroes were invited to a hot spring resort, after the Dark Matter Thieves invasion. While enjoying himself at the hot spring, he wasn't satisfied that Flashy Flash, Watchdog Man and Pig God did not participate in the battle, but were still invited to the resort and questioned their whereabouts. The next day after the ceremony, the heroes find Zombieman murdered, stabbed in the back by Atomic Samurai's katana. Metal Bat was questioned by Child Emperor who is investigating the case. Metal Bat defended himself stating he hadn't drink any alcohol since he is underage, but his statement rose some suspicion from the other heroes, especially Flashy Flash.
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 and dropped the case.
