David Sikela

• Also known as

David Sikela was the teen-aged son of Gayle and Asher Sikela, scientists in the Gotham City of a parallel Earth. They sent David to Earth-0 using a hypertime drive so he could escape the destruction of their world. When he was found by Superman and Batman, they discovered that David had developed super-powers. Kandorian scientists created a costume for him, modeled after a legendary Kryptonian freedom fighter named Hel-Oz. David was given the codename "Boy Thunder", and he accompanied Superman and Batman on some missions. David was later transported to Earth-22, where he was found by Gog. Gog trained David and he grew up to become Magog.
