The Super Friends desperately battle the World Beater, searching for his Achilles' Heel. An Achilles's Heel was any type of weakness a character might have had. Superman for example, was weakened by Green Kryptonite; making that his Achilles' Heel. The term originated from Greek mythology, a reference to the legendary Achilles, who was a demigod and a soldier during the Trojan War. References ↑ As seen in the comic story: The Cosmic Hit Man?
