Icon Series is one of the 13 extra Rarity types in Fortnite. This rarity is used in cosmetics that are based on notable celebrities, artists, and influencers. Icon Series was added in the game during the beginning of Chapter 2: Season 1 as the Creator Collab Series. With the announcement of Ninja, it was renamed to what it is now. Some cosmetics are not part of the Icon Series, even though they (technically) meet the requirements to be. (e.g. John Cena, Scenario, Wu-Tang is Forever)
