Robert E. O. Speedwagon

Born into the slums of London, Speedwagon's life changed forever when he witnessed the noble spirit of Jonathan Joestar, turning from foe to lifelong ally. He devoted himself to protecting Jonathan and his descendants across generations. Rising to become a powerful oil magnate, he established the Speedwagon Foundation as a lasting legacy. Though not a frontline fighter, his razor-sharp insight and fiery encouragement make him an irreplaceable pillar of support for his comrades.
