Scott William Pilgrim (b. September 27th, 1980) is the titular protagonist and one of the seven main characters of the Scott Pilgrim franchise. He also serves a major role in Scott Pilgrim Takes Off as the titular deuteragonist.
This is going off the debut of comic book characters. In the cases of characters who were introduced in other media originally and added to the comics canon later along (ex: Harley Quinn) it'll go by actual debut year.
