Gaea



In an alternate dimension from Earth, there floats a twin planet replica with oceans, continents, and ancient civilizations. Its size, mass, atmospheric composition, temperature belts, and even seasons are essentially similar to those of Earth, though given some of the jumping and acrobatic feats of some of the show's characters, it is possible that the gravity is slightly lower than Earth's. However, although people on Earth cannot see Gaea, people on Gaea see both the Moon and Earth in their nightly expanse.
