Notes

• Lithonians are only shown to be capable of transformation in the Marvel Comic adaptation of The Transformers: The Movie (and the accompanying bios from the Transformers Universe books). The film version doesn't show them transforming.

• The Lithonian models got recycled a few times for presumably non-Lithonians. The Junkion lady, Nancy, uses a Lithonian female model, and several members of the Hive from "The Rebirth" use the models before they enter their new Headmaster suits. There are also Lithonians visible in Iron Town in Victory, but it's more likely that these are indeed from Lithone.

• Space Pirates! recycled the model for the Lithonian escape craft seen in The Transformers: The Movie, using it as part of a Quintesson armada.

• Kranix and Arblus may not have been the only surviving members of the Lithonian species, as Lithonian character models are used frequently in the original cartoon. Don't worry Lithonian fans, they are still out there!

• In the April 1986 script of the movie, Lithone was "the planet of marble," and populated by creatures of living rock. Thus, the planet's name derives from the Greek word lithos, meaning "rock", this is similar to the Rock Lords from the GoBots movie.
