Lithone was one of the planets that underwent cyberforming by the crew of the Proudstar, injecting raw Ore-13 into the planet's core. Later, after sabotaging the ship, Kranix used a shuttle to try and return to Lithone, which he believed should have been sufficiently formed in the time since leaving, as it was one of the last places where he felt truly proud and happy regarding their mission.

Notes
- Per an April 1986 draft of the script to The Transformers: The Movie, Lithone was originally to be known as "the planet of marble," and populated by creatures of living rock. Hence, we can safely conclude that its name derives from the Greek word lithos, meaning "rock".
- In reality, the tidal forces of a binary star would
make planetary formation impossible.Fine, they found one. Are you happy now?
