Launched in 1997 as a promotion for Bandai's recent lines of vinyl Godzilla toys and running untill 1998, Godzilla Island
follows a team of humans created by the government in the year 2097, known as G-Guard, who have managed to gather Earth's kaiju onto an island somewhere in the middle of the Pacific Ocean
they call Godzilla Island. However, the island is also the focal point of a group of aliens, lead by Torema, who send out various monsters to take the island by force or attempt to sabotage G-Guard's operations. Inevitably, Godzilla and his allies end up in a fight with Torema's latest monster, and G-Guard must keep themselves safe from sabotage. Whilst not in the midst of crisis, G-Guard's primary goal is to study the monsters in their own habitat and learn more about the island's inhabitants, but a lot of events come up that endanger G-Guard and the monsters, forcing them to work together and fend off the threat.
Godzilla Island has examples of the following tropes:
- Heel-Face Turn: Gigan undergoes one by the end of his arc.
- Whole Plot Reference: The series' plot is somewhat similar to Destroy All Monsters, just with G-Gaurd looking to study them in their own habitat instead of just leaving them totally to their own.
- Loads and Loads of Characters: The many kaiju included in the series are; Godzilla, Godzilla Junior, Mothra, Battra, Rodan, King Ghidorah, Mecha-King Ghidorah and a new version of the latter called Hyper Mecha King Ghidorah, Mechagodzilla (both Heisei and a black-coloured Showa), Anguirus, Gigan, a new version of Hedorah called Neo Hedorah, two versions of Spacegodzilla (the normal Spacegodzilla and Super-Special Spacegodzilla High Grade Type Two), Destoroyah, Baragon, King Ceasar, Moguera, Megalon, Gorosaurus, Kamacuras, Jet Jaguar (in Medical and Firefighter forms), Gororin (an original creature), Kumasogami (under the name "Dororin" in the show) and, unique for any Godzilla media, Dogora.
- Long Runner: Lasted for 256 episodes.
- Canon Foreigner: Gororin, a giant cactus ball, was an original creation for the show. Kumasogami from Yamato Takeru was renamed "Dororin", but remained otherwise intact aside from the figure's paint scheme.
- Enemy Mine: Godzilla tends to team up with his robotic duplicate (of the Heisei series) to take down the latest threat to the island.
- Noble Demon: Gigan starts off as this, as he never goes out of his way to hurt anyone and always plays fair, even when dueling Godzilla.
- Sliding Scale of Anti-Villains: Gigan's a Type IV, through and through; he never does anything that could be remotely considered villainous, aside from having a dueling match with Godzilla (which even then, they both agreed upon). By the end of his arc, he leaves Earth on pleasant terms.
- Big Bad: Torema, for G-Guard, and Dororin for the kaiju.
- Canon Immigrant: Gigan's eye beams, which were never explicitly shown in any of his films up to this point. Kumasogami and Dogora, as well.
