In Egg Fu's first appearance, Steve Trevor is captured by the Chinese mastermind and turned into a human bomb. Egg Fu then launches Steve and a doomsday missile at the American fleet.
Wonder Woman intercepts Steve, who has become a deadly menace. She is unable to save him, but she redirects his path into the enemy missile. The explosion destroys the missile, Steve, and Wonder Woman herself, but the fleet is saved.
Informed of her daughter's demise, Queen Hippolyta gathers the remains of Wonder Woman and Steve Trevor and returns them to a laboratory on Paradise Island. Using an atomic structure reassembly beam, she restores Steve and her daughter. However, Steve's body is still infused with explosive energy. Wonder Woman finds that her own body has also become explosive, making them both a danger to the world.
They leave Paradise Island. Wonder Woman plans to use the explosive power against Egg Fu. The Chinese leader sends his troops against her, but they fail in their task to overcome her. A piece of anti-matter removes the explosive matter from Steve and Wonder Woman, then the Amazon defeats Egg Fu.
