Rex Goodwin's History
Rex and his brother Roman, were scientists who became Dr. Fudo's assistants for the development of Ener-D technology. The three of them worked on the project and making steady progress but at some point the Ener-D started behaving strangely and causing abnormal weather every time they tested it. Dr. Fudo wanted cancel the project before something bad happened, much to Rex's dismay.

Roman was made lead developer after Dr. Fudo's request to abort was rejected. Dr. Fudo managed to pass on three of the four control units; the cards "Red Dragon Archfiend", "Stardust Dragon" and "Black Rose Dragon", to Rex after being shot at for taking them. He begged Rex to stop the Ener-D project.
Rex went to find Roman and found him in a lab, having just amputated his arm. Roman handed Rex a container with the arm and told Rex to do what it took to defeat him after the Signers appeared. He ordered Rex to leave and hit a self destruct button, which resulted in Zero Reverse, so that he was reborn as a Dark Signer.

Rex survived the catastrophe but was left stranded in the Satellite area, which was now a recluded island. Rex constructed a Duel Runner and moved to a coastal part of Satellite. Nobody knew or found out who he was at the time because he never took off his helmet. Every day he used to stare across the waters dividing Satellite and New Domino City. One day, he began constructing a bridge to the city, hoping to find Roman.
Initially, people thought he was crazy, but came to help him after a while, after seeing his progress and determination. Some people frowned at the idea and forced construction to halt. Rex became wanted by Sector Security and his helpers abandoned the project. Rex ended up cornered by Security one day. Rather than be caught and spend the rest of his life in jail, he rode his Duel Runner along the bridge and flew off to the other end of the sea. No one who saw him jump could figure out if he survived or not, nor what his real identity was, thus they regarded him as a legend, and the incomplete bridge was later named Daedalus Bridge.
Goodwin managed to survive the jump off the bridge and made his way to the city, but lost his left arm in the process. Eventually, Goodwin replaced his arm with a mechanical one. Goodwin managed to make his way to becoming Director of New Domino City and Sector Security, as well as leader of a cell within the secret organization known as Iliaster, with Lazar as his all-purpose assistant. In order to make sure that the Dragon cards fell into the possession of their corresponding Signers, Goodwin released them to the public.
Since the original Ener-D Reactor, located in Satellite, was the gateway to the Underworld, Satellite was to become the battlefield. Goodwin, aware of this, made it illegal for residents of Satellite to migrate to the city and refused to complete the Daedalus Bridge, as doing so would have dragged the people of New Domino City into the situation. Goodwin masqueraded his beliefs of class and plutocracy with utilitarianism, and said that everyone must work together to maintain the delicate balance between Satellite and New Domino City. Goodwin continued Ener-D research in New Domino and used it to power the city. Zigzix led the project, but operated under Goodwin's strict vigilance to ensure the new Ener-D doesn't overload again.
Using his influence within the city, Goodwin began to locate the Signers. He found the Satellite resident, Jack Atlas, who had a Mark of the Dragon, and identified him as a Signer. Goodwin organized an escape plan for Jack, and promised him that he would live as a Duel King in New Domino. Jack complied, although it meant turning his back on and stealing from his friends. Jack apparently became Goodwin's protegé, but was really used for publicity and a tool in Goodwin's plans.
