Hypernauts is a proof of concept show produced by Foundation Imaging and Netter Digital Entertainment. To further prove that the computer-generated imagery and visual effects created in Babylon 5 were easily applied to other venues, the Hypernauts were born. ABC purchased thirteen episodes of the show from DIC Productions, L.P., eight of which ran on Saturday mornings for a single season in 1996 at 10:00 AM. ABC decided not to pick up the series for a second season, and did not air the five remaining episodes. The show was created and produced by Ron Thornton and Douglas Netter, its executive story editor was Christy Marx, who also wrote four episodes. Marx had previously written for both Babylon 5 and Captain Power. Another series writer was Katherine Lawrence who was nominated for a Writers Guild of America Award due to her script for Ice Bound.

Due to its lineage, Hypernauts featured relatively detailed designs of its technology and its aliens, as well as a fairly intricate plot, especially for a Saturday morning children's series. The premise of the series was that three cadets from the Academy of Galactic Exploration become lost in a Hyper Bubble (hyperspace) mid-jump and must band together with an alien named Kulai in order to survive in an unfamiliar part of the galaxy. Kulai (unbeknownst to the cadets) is a Chalim priestess from a planet called Pyria, a planet that was strip-mined by a warlike race called the Triiad, led by the Pyran traitor, Paiyin. The sole purpose of the Triiad is to wipe out intelligent races, and in the process acquire raw materials from their destroyed planets to continually create new war machines using automated self-replicating factory ships called "Makers".

The Hypernauts, as they are called in the academy, cannot match the Triiad's firepower with their own so they must rely on stealth, wits and (occasionally) their modified "mech suits" in order to escape the Triiad. They are based in an ancient abandoned exploration ship called the Star Ranger which is hidden in an asteroid field. The ship's obsolete AI is named Horten. For long-range missions they use a four-person "jump" ship called the Flapjack which is Hyper Bubble capable but has a short range, unlike a full-fledged exploration ship. They use the Star Ranger as a mother ship (with fusion engines) and with its vast database of explored nearby planets, they continue exploring (as they are trained to).

After learning of the Hypernauts (from their first encounter with Paiyin), the Triiad have activated and englobed the central region of the Milky Way Galaxy in a sensor net called "The Sphere of Interception", which can identify any end-to-end destination point for any hyperspace jump passing in and out of it (which includes any form of communication) so returning/calling home would lead the Triiad directly to Earth. The Hypernauts must keep the location of Earth a secret and somehow try to warn Earth of the Triiad's existence.
