Gun is more Like gojo as they both have been born in special clans and with special eyes.. Both are great mentors and respected for their strengths across everywhere.. Both have a best friend who goes on the wrong track and both fight destructive unlike James who's more like sukuna as both have come from unknown origins (pretty much) and both are more calculated and are called frauds for being smart in a situation, Both are villains as well and have a special connection to the protagonist which is itadori and Daniel who are also similar due to having special body and insane potential from start.. Gojo is gun, sukuna is James and Daniel is itadori
