Rally along with Yusei Fudo, Jack Atlas, Blitz, Tank and Nervin lived together in Satellite. Jack left the group after having differing goals with Yusei. Rally would often fluctuate between spending time with Jack and the others. He tried to encourage Jack to rejoin their friends.
After Jack is invited to New Domino City, he ties Rally up and leaves him float in a boat off the pier, in a scheme to get Yusei's Stardust Dragon and Duel Runner, which were necessary to get to New Domino. Yusei saves Rally, who apologizes for the trouble.
Later Rally acquires a chip for Yusei's new Duel Runner. In the Japanese version, his friends worry Rally might have stolen it. In the English version, Jack planted it where Rally would find it. After giving it to Yusei, they are confronted by the Sector Security, who are looking for Rally. They tell Rally it is pointless to run, since they can track him with the signal emitted from the criminal mark. But Yusei uses his laptop to jam the signal. Yusei speeds off to distract the securities, while Rally and their friends make their escape.
Yusei clears any extra criminal record Rally obtained that day by defeating a security, Tetsu Trudge in a Duel, where the securities were to forget the events of that day, if he won. Before Yusei parts to duel Jack, Rally gives him Turbo Booster, which was Rally's most prized card. In the English version, it was said to have belonged to his father.
