Robert E. O. Speedwagon (ロバート・E・O・スピードワゴン Robāto Ī Ō Supīdowagon) is a core ally featured in Phantom Blood and is a minor ally in Battle Tendency.

Robert E. O. Speedwagon is a hot-blooded and honorable street thug and later businessman.

Despite his activity as a hoodlum, Speedwagon is a righteous man. Due to his ability to "smell out" the personality of people, he had recognized Jonathan's noble spirit during the events at Ogre Street[4] and accompanies him on his further journey to defeat Dio, whose facade as a cover for his naturally evil behavior was easily denied by Speedwagon.[5] Speedwagon is incredibly loyal to his friends, befriending Jonathan was in part due to the gentleman being kind to his partners in crime. He will try to do anything to help them, and even after Jonathan's death, Speedwagon remained friends with Erina out of respect for Jonathan.
