Thunder 3 Episode 2: “MULTIVERSE” Synopsis
The story picks up immediately after the dramatic events of Episode 1.
After Futaba is kidnapped by a mysterious giant flying battleship, Pyontaro fearlessly jumps aboard in an attempt to save his younger sister. During the pursuit, he is thrown from an incredible height—an impact that should have been fatal.
Surprisingly, Pyontaro survives completely unharmed.
He soon realizes that the strange world he has entered follows entirely different rules. In this mysterious multiverse, objects and environments appear to be unusually fragile, while Pyontaro and his friends possess incredible physical abilities that resemble those of superheroes.
With their newfound powers, Pyontaro, Tsubame, and Hiroshi decide that their first step is to find their alternate selves living in this world. They hope these counterparts may hold the key to locating Futaba and understanding the secrets behind the bizarre universe they have entered.
However, meeting another version of yourself may prove to be just as dangerous as confronting the unknown enemies waiting ahead.
