Speculation has risen among fans that Serges is actually the mind of Dr. Wily transferred into a Reploid body. Some dialogue from the Japanese version has him talk about Dr. Light, X's creator, and his appearance and his tendency to rely on machines for transport and attacking resembles Dr. Wily in many ways. Keiji Inafune has never confirmed or denied the fact, and has seemed reluctant to do so, suggesting the theory could be true.
