Crawltanks are Space Pirate battle drones used for ground combat. They resemble spider-like tanks that are about the size of Samus's Morph Ball. They are simple enemies that fire beams and can be destroyed with three simple hits from the Power Beam, two from the Plasma Beam, or one from the Nova Beam. The tanks can enter Hypermode and deal more damage and sustain many more attacks, but are still a relatively simple enemy.
- "Crawltanks are mobile, ground-based defense drones, but are easily destroyed by standard weapon fire. They can be equipped with different cannons, including a Phazon Beam system. They are not built for sustained combat, and are better suited for light patrol and security roles." — Logbook "Crawltank" (Metroid Prime 3: Corruption)
