Well, after being inspired by KaijuX's list for G4 (and the fact that I've JUST REACHED 1000 PAGEVIEWS WITHOUT POSTING ANYTHING! THE WORLD IS CRAZY!), I've decided to post an old idea of mine for a possible G4 game. Alright, here we go:

The Roster:

Earth Defenders:
Godzilla 2000 (Godzilla 54’ and 90’ are unlockable and will replace Godzilla 2000 in Story Mode when they are choosen.)
Anguirus
King Caesar
Mothra Leo (The original Mothra was killed by SpaceGodzilla when he returned to Earth in my story. Now, Leo is trying to get some revenge on SpaceGodzilla for killing his mother. And yes, the Elias will make an appearance too.)
Fire Rodan
King Kong
Gamera

Global Defense Force:
Kiryu
Jet Jaguar
Super-MechaGodzilla (with detachable Garuda)
Moguera
Mecha-King Ghidorah
Mechani-Kong (BIG maybe…..)

Aliens:
SpaceGodzilla (he’s the leader. More to that later.)
Gigan Final Wars (Showa is unlockable and will replace the Final Wars Version in Story Mode when selected.)
Megalon
King Ghidorah (I don’t really care what version it is. Ghidorah is Ghidorah for me.)
MechaGodzilla (Appears as the fake Godzilla at first)
Orga
Monster X (No Keizer Ghidorah. We already have one Ghidorah, or two, if you want to be exact.)
Krystalak (Didn’t expect him here, huh? I will make everything clear when I tell the story, so don’t worry.)

Mutants:
Destoroyah
Titanosaurus
Biollante
Megaguirus
Hedorah (His stage is Osaka, obviously.)
Gyaos (Hyper Gyaos and smaller ones)
Iris (He only cares about one thing: Killing Gamera. If he gains some power while doing so, he will gladly take it.)
Battra (Reawakened when the chrystals appear for a second time. Since Mothra was killed by SpaceGodzilla, he goes for the second best target: Mothra Leo.)
Kumonga
Kamacuras
Obsidius
Gorosaurus (the King Kong escapes version, not the one that helped kick King Ghidorahs ass in Destroy All Monsters. Him, Kumonga and Kamacuras were still kept on Monster Island when the G:U Event happened but they were able to flee when the Chrystals started to grow again.)

Non-Playable Bosses and Cameo appearances:
Gotengo
Ebirah
Minilla (You will have to save his ass from a beating on Monster Island. He will also appear in the backround on Monster Island when you play as Godzilla, cheering you on.)
Gabara (He is the one who wants to give Minilla the beating. He will be the Practise Mode punching bag. I still have to decide if I make him playable or not.)

Bonus Characters:
Baragon
Varan
Manda (Manda replaces Anguirus as the third Yamato Guardian from the original script. I got that idea from KaijuSamurai’s NEO Manda)
Zilla Jr. (The Cartoon Version. Is unlocked when you beat the game with Godzilla 2000.)
Gigan Showa
Godzilla 54’
Godzilla 90’

The Story:

It’s been over two years since the Chrystals crashed on Earth and sent the world into chaos. The Vortaak were beaten again and SpaceGodzilla was succesfully defeated by Godzilla, Anguirus and Kiryu. But before the Vortaak fled from Earth, they took the body of SpaceGodzilla. Desperate to finally take over the world from these stupid humans, they plan to revive SpaceGodzilla and use him as a weapon against the Humans and the Kaiju. They made him stronger and better then ever before ……… but he was too much to handle, even for them. The sinister space demon turned on his saviors and killed everyone. Using his telephatic powers, he took control of the Monster that were under the Vortaak’s command. Megalon, Gigan, Orga, MechaGodzilla, King Ghidorah and a secret weapon that still slumbers in the Meteor Gorath, Monster X. Now, he has set his eyes on one thing: Getting revenge on the King of the Monsters, Godzilla……..

On Earth, the effects of the chrystals are still more then clear for everyone. Most of the Chrystals were wiped out by the GDF and the Earth Defenders, but there are still many more left. If that wasn’t enough, a new species of Kaiju emerged: The Gyaos. Created by a old civilization, they were kept in hibernation for thousand of years, but now, thanks to the chrystals, they have awaken and there numbers are growing fast. But the Earth also gained a new Guardian in the giant turtle named Gamera, another monster created by the same civilization that created the Gyaos. The Gyaos aren’t just dumb animals, though. They are continuing to evolve into bigger and stronger versions of themselves, called Hyper Gyaos. And, sooner or later, one of them will become different …….. and stronger then the rest.

Most of the Mutants were captured by the GDF and coralled onto Monster Island. Only Biollante and Destoroyah are still free. They vanished as soon as SpaceGodzilla was defeated. Krystalak was absorbed by SpaceGodzilla in the final battle.

The Earth Defenders are helping Gamera with the Gyaos invasion, but not all of them. King Caesar is sleeping again, waiting for a new call of help. Baragon and Varan suddenly disappeared and weren’t seen since. And Godzilla went back to live with his son, Minilla.

But soon, they have to come together again to face a new, greater evil, because SpaceGodzilla is coming closer. He will be arriving on Earth shortly, to get revenge on every Kaiju that was against him………..

And now, some notes on the Kaiju revelance in Story Mode:

1.) Krystalak will be a lacky for SpaceGodzilla in story mode. SpaceGodzilla is able to create many Krystalaks out of the chrystals he spawns. They are nowhere near as strong as the original one, but their numbers help. They are just there to spice up the battle against SpaceGodzilla anyway. If you choose Krystalak in story mode, though, you will just battle SpaceGodzilla in a one on one fight.

2.) The three Yamato Guardians will appear when you destroy their shrines and attack the Alien and Mutant factions. They are not part of the Earth Defenders nor are they part of the GDF. They are their own group.

3.) There is a Minigame where you have to protect the Caesar statue from a Alien until he is reawakened. If you fail that mission, King Caesar is destroyed and will not be able to help you for the rest of the story.

4.) In the Earth Defender event, King Kong will be under mind-control at first. When you are able to break the control, King Kong will join you as an Earth Defender.

5.) You will battle Ebirah in an underwater battle when you play as Godzilla (or any other Water based Monster for that matter) and move from one area to another. I was thinking that it could be a quicktime event where you have to press a specific button when it appears on screen. Those are used a lot lately, so I'm not sure.

6.) The Mutants battle each other as much as they team with each other. They have no problem to betray their partner when they can get some power for it. Remember that when you join them.

Here we go, that are my ideas for a fourth Godzilla game. Some of those need some rethinking (for example, how can Mecha-King Ghidorah still exists while the original one is alive?), but I think it's pretty good. And if there is a problem to secure the license for Gamera and Kong, just take them out. They aren't that relevant to the story.
