Kaiju Ghost

Godzilla is a boss in Luigi's Mansion 3. In this game, he changes his role from a protagonistic character like in his home series to an antagonistic boss. Luigi fights him on the eighth floor, which houses the Paranormal Productions studio.

Battle
When he makes his entrance, Godzilla tears through the city set. Luigi screams when he sees him, but he holds his guard. Godzilla attacks by breathing fire. These flames deal damage to their target. However, he can be damaged if Luigi uses his Poltergust G-00 to push the fire that Godzilla breathes from his mouth to attack the boss and knock him over. Once he takes three hits from his own flames, Godzilla turns into a Gooper. In his second form, Godzilla has 100 hit points. Once Luigi sucks him in, Godzilla will be defeated. Director Morty remains true to the promise he made and relinquishes his elevator button to Luigi, allowing the green-clad hero to continue to the ninth floor.
