The 'Amber Heard Mercy Cosplay' meme surfaced in September 2023 after Elon Musk shared a private photo of his then-girlfriend Amber Heard dressed as the character Mercy from Overwatch. The reveal came following a mention in Walter Isaacson’s biography of Musk, which detailed how the billionaire had asked Heard to dress up for him because she reminded him of the character. The image quickly became a viral sensation, with users utilizing the template to comment on Musk's eccentricities, celebrity relationship drama, and the sheer absurdity of the crossover between Hollywood and the gaming world. It is typically used to mock obsessive requests, niche fandoms, or the surreal nature of billionaire private lives.
