Dongo is a high-performance, multifunctional robot aboard the Minerva. With an extendable body, its lower half is equipped with both tracks and wheels, allowing it to switch between them depending on the terrain. Its main duties include staying behind to watch the ship, providing support and analyzing data while the crew is away. Despite being a machine, Dongo has human-like traits, often reading adult comics during downtime.
The English dub used an Amiga 3000 computer to "voice" Dongo.
