Gaia Saver: Hīrō Saidai no Sakusen (ガイアセイバー ヒーロー最大の作戦?, lit. "Gaia Saver: Greatest Hero Operation") is a 1994 Super Famicom video game that was only released in Japan.
Gaia Saver is a science fiction role-playing game where the player has to fight wielding an alliance with the super deformed heroes. The primary objective is to save the Earth. The heroes advance in three parties. While the story progresses, various heroes become companions, and participate in the battle.
The Earth is under attack, devastated by terrorist activities conducted by Shocker, invading alien monsters, natural disasters such as earthquakes, tsunamis, tornados, and finally, colony drops conducted by the Principality of Zeon. Earth's military, including the Earth Federation Forces, is powerless to protect the planet.
Earth Federation Forces' main headquarters, Jaburo, was under an all-out attack by Zeon's forces. Thanks to the intervention of the Ultras, however, Amuro Ray, as well as the rest of the White Base crew managed to escape to the SSSP headquarters in Japan. While there, the heroes agree that none of them have the power to save the world by themselves, and agreed to form an "alliance" to protect Earth against the enemies that threaten it.
Gundams, unlike Kamen Riders and Ultras, are operated by human pilots. Since mobile suits are too big to fit in-doors, Gundam pilots are forced to switch to Petite Mobile Suits within in-door dungeons.
- Amuro Ray / Gundam F91→ Gundam → ν Gundam → Gundam Killer
- The protagonist of the game, though he temporarily becomes an enemy when he heads to space alone to stop the Zeon-Shocker Alliance's colony drop, only to end up captured and brainwashed. He became the pilot of Gundam Killer, a mobile suit designed specifically to destroy Gundams. Though his teammates managed to undo his brainwashing, and he rejoined the team.
- Seabook Arno / ν Gundam → F91 Gundam
- In the late Gundam, ν Gundam, the transfer of the aircraft carried three Gundam F91.
Ultras can only fight for a limited period of time before their Color Timers begin to flash, and they will eventually become incapacitated once the time runs out. Unlike Gundams, they can shrink in size to fit inside in-door dungeons. They are the only characters who can use healing skills.
