The Ruby Rose Batwoman casting controversy erupted in 2018 when the CW announced the Australian actress would play the titular role in the Arrowverse. While the move was initially praised for LGBTQ+ representation, a wave of social media backlash followed, targeting Rose's acting credentials and her perceived suitability for the comic-accurate portrayal of Kate Kane. The intensity of the 'Twitter mob' led Rose to delete her social media accounts, turning the casting decision into a case study of online fandom volatility. Memes about the situation typically highlight the divide between studio decisions and fan expectations, or poke fun at the chaotic nature of the CW’s superhero casting history before Rose eventually departed the series after a single season.
