Dr. Dolphin

ドルフィン

A British engineer known as Dr. Gilmore. Depending on the version, his wife was either maimed and disfigured in a V-1 strike and later committed suicide, or was shot dead.
He began developing a machine designed to disable weapons and other machinery, but was abducted by Neo-Nazis (or Black Ghost itself) who wanted to exploit the "Mad Machine" for their own purposes, and was taken to Antarctica. This required his rescue by the 00 cyborgs.
He was inexplicably renamed "Dr. Kozumi" in the 1968 anime, while his surname was rearranged to "Findol" in his 2001 counterpart.
