Captain Onishima is the secondary antagonist of Jet Set Radio, a delusional police officer obsessed with destroying the punks of Tokyo-To, including the GGs. He is seen as deranged, and his obsession with hurting and arresting rebellious teens may come off as “off.”
Onishima has a small-temper and will go to extreme lengths to terminate anyone who may pose as a threat to him. He is obsessed with removing punks and teen gangsters from the city, which leads to them harassing Onishima and tagging him with their personal graffiti.
- IGN ranked Captain Onishima 95th of Top 100 Videogame Villains in 2010.
- Onishima does not make an appearance in Jet Set Radio’s sequel, and did not make another physical appearance until 18 years later, with the release of SEGA Heroes.
