GamesRadar reports on fan speculation that Poison Ivy could be a major villain in *The Batman 2*, linking a recent casting rumour to an older social media post by the film’s co-writer, Mattson Tomlin. The article matters mainly as an indication of how closely fans are scrutinising the sequel, which remains largely secretive despite being a little over a year away. It does not confirm any casting or plot details, but suggests that online chatter around the film is intensifying.

The piece says unofficial DC-focused accounts have claimed Scarlett Johansson may be playing a more grounded version of Poison Ivy, though it stresses the rumour should be treated cautiously. It also notes that Tomlin posted about *Batman* #181 in July 2025, the 1966 comic that introduced Poison Ivy, which fans now see as a possible tease. Other rumoured elements mentioned include possible roles for Sebastian Stan and Brian Tyree Henry, hints of the Court of Owls, and a confirmed cinema release date of 1 October 2027, with Robert Pattinson returning alongside cast members including Andy Serkis, Colin Farrell and Jeffrey Wright.
