While Deathsaurus's main vessel, the Decepticon Space City, was imprisoned in the Dark Nebula, the Thunder Arrow was his mobile base on his quest to gather enough energy to free his mighty fortress. It was a huge vessel that could swallow up an entire oil tanker with ease.
It was impressively armed, with four main cannons on the nose, guns on the deck and numerous smaller gun ports all along the side. Despite this impressive armament, however, it often wound up being damaged by the Autobots in battle.
- The Thunder Arrow was based on Skystalker's shuttle.
