Gaia (Greek: Gaea) is the planet where Thunder: A Hero's Welcome takes place on, and is the largest known rocky planet known in the solar system where Gaian humans reside. Gaia, along with some of its neighboring planets orbit a large star similar to the sun which the Japanese of Earth 1.0 dubbed "Amaterasu" after the Shinto goddess of the sun. However, Gaia orbits Amaterasu in, what is known as the "Goldilocks Zone".


Gaia bears an appearance very similar to Earth 1.0 in the past. It is a large, rocky planet with small patches of land on the north and south poles and lush, green continents with small desert regions. The water on the planet is safe for habitants to sustain on. However, unlike Earth 1.0, both of Gaia's north and south poles have land, whereas Earth 1.0 only has land on its south pole. It is nearly a perfect sphere in shape.

Location in Space

Gaia is housed within a large galaxy known as Milkdromeda, not too far away from the old solar system where Earthling humans and wildlife migrated to Gaia from. This is known as the old planets, moons, and dwarf planets can still be seen from the surface of Gaia, including the intro to TAHW in which Saturn and two of its most commonly known moons, Titan and Mimas are shown during the day, orbiting Saturn.

Geological History

Very similarly to Earth 1.0, Gaia originally, several billion years ago had only one super-continent named Molliangaea, which was torn apart and separated into several different continents by plate-shifts. The continents are still technically considered to e Molliangaea, but in separate pieces, scattered across Gaia; most of which are based and inspired off of real continents from Earth 2.0, such as Asia, Australia, Alaska/Canada, etc. Gaia has a hot, iron inner core which burns at 6,2500 degrees Celsius. The outer core holds precious metals and gem stones such as iron and gold nuggets, diamonds, crystals, and other valuable resources that can be found on other planets.

  • Gaia was originally named "I~ensu" before the name Gaia was introduced; I~ensu being more of a beta name for the planet.
  • Gaia is heavily inspired from the Pokémon world.
  • Although slightly larger, Gaia is based somewhat on an exoplanet known as Kepler-452b, also known as "Earth 2.0."
  • Gaia is named after a Greek/Roman goddess of the same name. The same can be said for the satellite in which it holds, known as 'Pontus'.
