Teen Force focused on three superhumanly gifted young students who hail from an unknown alternate universe which is located beyond the confines of the mysterious Black Hole X, which serves as a gateway into the universe in which the other main characters from Space Stars exist.

The Teen Force consists of Kid Comet, who possesses tremendous levels of superhuman speed, enabling him move at speeds exceeding the speed of light, and can even move quickly enough to travel through time; Moleculad, who can control his molecular structure for various effects; and Elektra, who possesses the psionic disciplines of telepathy, telekenesis, and teleportation. Accompanying them are a pair of diminutive blue-skinned aliens named Plutem and Glax, also known as the Astromites. Their principal enemy in the series is Uglor, a mutant native and tyrannical ruler of the planet Uris (whose inhabitants are a race of evolved simians) in Galaxy Q-2. Uglor's mutation granted him bird-like wings and the ability to generate destructive energy blasts from his bionic eyes, which allowed him to see through Space Ghost's Inviso-Power and Elektra's telepathic illusions.
