Invasion of the Brain Creatures

Overview

While in space, Batman and Superman are possessed by brain creatures, who soon control Wonder Woman, Robin, and Aquaman. Under their influence, Superman hurls asteroids at Earth, causing fissures, fires, and floods. Wonder Woman overcomes the mind control, and with a magnetic cloud, the creatures are expelled from all the heroes. She then devises a plan to send an electrical current through Earth, forcing the brain creatures to flee and freeing Superman, Batman, and Aquaman.
