Lightning Max vs. Deep Sea King is the battle between the A-Class hero Lightning Max and the Demon level monster the Deep Sea King.
The Deep Sea King began his invasion on the surface of the Earth with his Seafolk. He arrived in J-City, where he struck A-Class hero Stinger for killing some of his henchmen. The city alarm announces that the disaster level of the Seafolk invasion has been raised to Demon. In addition, the citizens are advised to evacuate the city. As the Deep Sea King was walking down an empty street, Lightning Max was observing him from afar with a telescope. Lightning Max was contemplating whether he should fight the monster or wait for reinforcements. Suddenly the Deep Sea King sneaks up, startling Max and attack the monster with his Lightning Kick, but the attack has no effect at all.
Deep Sea King punches Lightning Max into a building. Max attempts to defeat Sea King with his Flying Backwards Roundhouse Kick but it is ineffective and he is defeated by Sea King and is sent flying out of the building only to be caught by Puri Puri Prisoner.
