Like others of her race, Moya was captured by a Peacekeeper squad at a young age and was bonded with a Pilot, who serves as the Leviathan's navigator, operator, companion, and link to the crew of the ship. Leviathans are ships of peace, and as such have no offensive capabilities. They do have an impressive defensive maneuver, however, called starburst, which allows the ship to travel at incredible speed through a tear in space-time. Moya is maintained by DRDs (Diagnostic Repair Drones), which are small, beetle-like robots that Leviathans build as they grow. They help with Moya's upkeep, by repairing and maintaining Moya. DRDs also play a major role in many of the adventures, helping John and the crew; the most notable DRDs are named 1812, One-Eye, and Pike.
