A massive appeal to players of Overwatch 2, often even more so than the gameplay itself, is the large number of cosmetic skins that can be collected for each player's mains, or most favorite heroes and villains. Crossover collaborations have been present in the game since Overwatch 1, with skins including LEGO Bastion, Illidan Genji, and Tyrande Symmetra from World of Warcraft, as well as Kerrigan Widowmaker from StarCraft, for example.
