So some time back in 2008, #Symantec created "Norton Fighter" (ノートン・ファイター), a character created to promote the Norton Antivirus software, apparently trying to capitalize on the otaku wave at the time.
Can't really tell what sort of audience they were trying to target with it (kids from the Power Ranger era? Aging Ultraman fans?), but gotta appreciate the whole effort behind the creation. There's a whole story behind him!
