Nah I’d win

Necrozma can absorb all the light in a universe, and become a god-like being of death and destruction.

Godzilla is just a big lizard with lasers.

Weird this is implying that a FEAR Rattata can also kill Godzilla, but I digress

Necrozma preys on rare species

Godzilla will win because in Pokémon universe he is 600 stat Dark type Tyranitar and would super effect Necrozma while necrozma’s most powerful moves will not effect him.
