The Plumber Power Core is a power source for the Plumber Headquarters.
The outer part of the power core looks like a big clear-green sphere with gray circular panels on every eighth. The inner part of the power core is mostly a darker gray with indented circular panels on every sixth. The outer part of the circular panels on the inner part of the power core are a lighter gray in a gear-like pattern, the middle part of the indented panels are a black-gray with four black lines appearing to radiate from the center, and the inner part of the circular panels are mostly green with a single black dot in the center. Below the power core are several computers that control the power core. To the sides of the power core are multiple generators that Gorvan set to overload and caught fire in the episode Mud Is Thicker Than Water.
- Besides powering the Plumber Headquarters, it also powers a nearly-unnoticeable force field to keep prisoners from escaping.
