Produced in-house by Netflix Animation, the show is McCracken's first to have a serialized format, as well as his second foray into the superhero genre, having previously created The Powerpuff Girls. Illustrated in a "retro 2D" style inspired by comics such as Dennis the Menace and The Adventures of Tintin, the series follows Kid, a young boy who gets a chance to become a superhero and fight evil aliens alongside other characters with different abilities.

Plot Kid Cosmic follows Kid, a 9-year-old boy who 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, consists of Kid's grandpa, George "Papa G" (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 that grants healing abilities, and learn further revelations about Erodius and the world they are currently in, requiring that they must make great sacrifices.
