The Planet-Splitter (1x15)

:

Eccentric, ingenious scientist Dr. Laban has stolen the largest diamonds in the world to power his "planet splitter," a device capable of splitting a planet in half, intending to tow half of it to Earth as a second moon. While the Super Friends guard the remaining diamonds in the world, Wendy and Marvin follow Dr. Laban to his secret laboratory, where Laban tells him of his plan.
