Sea Monster Arc
Lightning Max is seen observing Stinger's defeat at the hands of the Deep Sea King through a telescope and decides to go and fight the monster himself until reinforcements arrive. But before he can even act, the Deep Sea King appears behind him in an instant smiling menacingly. This startled Lightning Max and he quickly attacks the monster with his Lightning Kick, but it has no effect on him and the Deep Sea King casually remarks that it hurt a little. Lightning Max realizing he can't win tries to think of a way to escape, but before he can move he's punched with full force by the Deep Sea King, who sends him flying into the building across from them. The building begins crumbling down and Lightning Max tries to escape, but is confronted once again by Sea King. In a desperate effort, Max unleashes his Flying Reverse Roundhouse Kick, but once again it has no effect on Sea King and he knocks out Lightning Max with a punch and sends him flying once again into the streets below where the building threatens to crush him. Luckily he is caught by the S-Class hero Puri-Puri Prisoner before the crumbling building crushed him. He was later hospitalized alongside Stinger. While reading the newspaper, about the incident and the hero who took their credit, Puri-Puri Prisoner appears, much to their horror, and is about to give them both his special medicine, but Lightning Max and Stinger ran away with fear.
