Godzilla 54

Godzilla 54 is one of the two unlockable generations of Godzilla next to Godzilla 90's. In fact, he's the very first Godzilla generation, who first appeared in the 1954 movie, "Godzilla." Like Godzilla 2000, he defends earth from aliens and mutants that want to destroy or take over earth, but doesn't include "humans" in his list of things he'd protect.
