The Transformers: The Movie
- Voice actor: N/A
Arblus was one of the few Lithonians quick enough to escape their home planet when Unicron arrived and began to feed. With his friend Kranix, he crashed on the planet Quintessa, where he was put to trial by the planet's inhabitants, the Quintessons. Not long thereafter, two other captives, Hot Rod and Kup, were being herded into cells just as Arblus's trial was reaching its end, and watched as he was sentenced and fed to the Sharkticons.
- The character model for Arblus features a spaceship mode that has yet to be used in any fictional depiction of him.
- Arblus and Kranix may not have been the only survivors to escape Lithone, as Lithonian character models are used often in the original cartoon and in the Marvel comics.
