When the fleet escorting the ship attacked the Red One, damaging it, Stitch used the Red One's hyperdrive to escape. However, as the damage the fleet caused to the Red One had disabled its navigation system, when the Red One came out of hyperspace, it crashed on Kauai, Earth. Stitch survived the crash, but the Red One apparently blew up on impact.
In "Bonnie & Clyde", despite the Red One's obliteration, Jumba was able to rebuild it, much to Stitch's delight. Lilo and Stitch then used the Red One to capture Bonnie and Clyde.
The Red One's design appeared to vary in all of its appearances: in the original film, it was red with a vertical white stripe; in the TV series, it was red with a horizontal white stripe; and in Stitch!, it had a more triangular design.
