A potential Overwatch and NieR: Automata collaboration has been leaked after a now-deleted YouTube Short from Blizzard's channel briefly showed hints of the crossover. Fans captured screenshots as evidence, sparking widespread online discussion about which heroes will receive the themed skins.

Based on the leaked image, five heroes are slated for skins: Lifeweaver as Adam, Venture as A2, Wrecking Ball as 9S, Kiriko as 2B, and Mercy as Commander White. While most pairings seem logical, the choice of Kiriko as 2B has drawn criticism from fans who argue Genji, with his katana, would be a better fit, noting Kiriko's frequent new cosmetics.

On social media, many players expressed fatigue over Kiriko consistently receiving new skins. The leak suggests the collaboration items should arrive around March 10, with an official announcement expected imminently.
