Bruno is a mysterious young man from Satellite. He appears to possess similar skills to Yusei regarding mechanics and technology. Bruno appears after washing up on-shore, taken in by Yusei, Jack and Crow at Ushio and Mikage's request. While with them, Bruno shows off extraordinary skills in machinery and computing, possibly more so than Yusei. Using these skills, he is able to identify the theft of an engine project he and Yusei complete as Jeager and play a role in getting it back. When the WRGP approaches, Bruno becomes an official member of Team 5D's, working in the pits.
