The Dynamo Unit appears in Metroid Prime.
Resembling a large tower with various spinning parts and components, it is responsible for the power surges occurring in the Phazon Mines. The scan states that it has multiple malfunctions and should be destroyed immediately. After Samus destroys the Cloaked Drone guarding the room, a hatch on the floor opens and leads into a chamber underneath the floor. Getting through this maze is key to destroying the unit as directly underneath is the Power Bomb. Samus destroys the dynamo unit using one of them, in a cutscene, before Bomb Jumping out.
