There are tons of Fortnite collaborations, with new ones coming each season. Just this season has seen Dune, Venom: Let There Be Carnage, DC Comics and more. Fortnite is always introducing new crossovers, so the older ones keep getting a little bit more rare with every update. This is especially true for skins that don't return for a while after their initial release.These make for some of the rarest skins in the game, as collaborations are hit or miss depending on what brand they are and how the players feel. Many players don't like the overabundance of collaborative skins, so they don't buy them, thus making them even more rare. Here are a few of the rarest collaboration skins in Fortnite Chapter 2 Season 8.5 of the rarest collaborative skins in Fortnite this season5) Gridiron (NFL collaboration)The NFL collaborative skins, which could be customized for any NFL team's jersey and any player's number, haven't been in the Item Shop in 630 days.
