- Titanosaurus, Biollante Hedorah, Varan, MechaGodzilla 74 and Godzilla 54 were all considered to be in the game. Titanosaurus was taken out because of a licensing issue.
Biollante was taken out for political reasons for stemming blood from the bad blood between Atari and Pipeworks!
- Gigan, Jet-Jaguar and Destroyah were all going to have the ability to fly. Gigan had alot of powerful moves so thats why he lost his ability to fly. Jet-Jaguar and Destroyah lost their ability to fly because it was to hard to control it.
- Rodan was originally going to have a rail shooter level but it was to hard to string up together so it never made through.
In the Japanese version of the game Baragons flame does 20% more damage than in the American version. MOGUERA and Godzilla 90's also had their moves do more damage.
