Plot
Kid Cosmic follows Kid, a young boy who naïvely fantasizes about becoming a superhero, living in a junkyard in a thinly populated stretch of desert in New Mexico. When a spaceship crashes in the area, he discovers it has onboard five "Cosmic Stones of Power" that give him the chance of fulfilling his dream. When the stones attract alien invasions, he forms a motley team of superheroes to defend the Earth from them. This team, with each member having a stone giving them a unique power, consist of Kid's grandpa, George "Papa G" Mulligan (Old Man Many Men), who can create multiple clones of himself; Kid's friend Jo (Portal Girl), who has the ability to teleport; Rosa (Niña Gigantica), a four-year-old girl who can become a 40-foot giant; and Tuna Sandwich (The Precognitive Cat), a cat that can predict the future with a third eye on his forehead. They are accompanied by Stuck Chuck, an alien invader stranded on Earth after the destruction of his ship. Stuck Chuck's mission is to steal the Cosmic Stones for his Great Leader.
In the second season, the Local Heroes are teleported into space and have to go on a quest to find the other eight Stones of Power to fight against Erodius the Planet Killer.
In the third and final season, the Local Heroes, now the Global Heroes, find out that there is actually a fourteenth silver Cosmic Stone of Power of healing, and learn further revelations about Erodious and the world they're currently in, requiring that they must make great sacrifices.
