While in space Batman and Superman become possessed by brain creatures. The brain creatures ultimately take over the minds of Wonder Woman, Robin, and Aquaman when it appears that the Wonder Twins are successfully defeating Batman and Superman's asteroid attack of Earth. Batman and Superman, while under mind control, continue to attack the Earth by firing huge asteroids on the surface. Superman uses his speed to hurl multiple asteroids at the Earth's surface which causes fissures, fires, and floods. Wonder Woman uses her mental powers to over-come the mind control and with the help of a magnetic cloud the brain creatures are expelled from the brains of Wonder Woman, Aquaman, Robin, Batman, and Superman. Wonder Woman then devises a plan to send an electrical current throughout Earth which causes the brain creatures to flee the planet and leave the minds of Superman, Batman, and Aquaman.
