George II Joestar
George resembles his father Jonathan and his son Joseph. He is only seen wearing a military dress uniform.
Assumed to be a capable fighter pilot, George was one of the first to fly an aircraft during World War I. It's hinted that he may have had a talent for the Ripple much like his father and son, though he was never given any training to properly use it.
