The Neathians are a species from Bakugan Gundalian Invaders that also appear in Super Smash Bros. Crossover. They retain their peaceful nature. Fabia is so far the only Neathian to be a main character, but in Season 5, Queen Serena, Linus Claude, and Captain Elright were introduced. In Season 9, another Neathian was introduced known as Sellon. However Sellon is an antagonist Neathian, unlike the other Neathians.
