Hiroshi Jinkawa
From Multiversal Omnipedia
Hiroshi Jinkawa was a family friend of Goro Ibuki who stepped in to assist the scientist in raising his younger brother Rokuro after their parents died. He wound up proving a great asset to the Ibuki brothers when Seatopian agents came seeking to steal Jet-Jaguar and gain control over him. Proving quite the man of action, when the lead Seatopian agent had his assistant take Goro and Rokuro to meet Emperor Antonio (in Seatopia), Hiroshi escaped captivity and pursued the truck carrying them. Despite the lead agent sending more agents after him, Hiroshi escaped them following a car chase and was able to rescue his friends.
