A potential collaboration between Overwatch and NieR: Automata appears to have been leaked after a now-deleted YouTube Short on Blizzard's official channel briefly showed hints of the crossover. Fans captured screenshots as evidence, confirming the partnership between Blizzard Entertainment and PlatinumGames. Online discussion has since focused on which Overwatch heroes will receive the themed skins.

Based on a screenshot shared by OverwatchCavalry, five heroes are slated for skins: Lifeweaver as Adam, Vendetta as A2, Wuyang as 9S, Kiriko as 2B, and Mercy as Commander White. While most pairings are seen as logical, the choice of Kiriko as 2B has sparked controversy. Fans argue that Genji, who wields a katana like 2B, would have been a more fitting choice, suggesting Kiriko was selected due to her popularity and recent Hello Kitty collaboration skin.

On social media platforms like Reddit, many fans expressed fatigue over Kiriko frequently receiving new skins, humorously labeling her the game's "cash cow." According to the leak, the skins are expected to arrive on March 10, with an official announcement likely imminent.
