She returns as a playable character in Marvel vs. Capcom 3: Fate of Two Worlds and Ultimate Marvel vs. Capcom 3 (2011), where her design is based on her appearance in Resident Evil 5, available as downloadable content. In addition, she also makes a guest appearance in Under the Skin (alongside Carlos and Nemesis) and has a character card in the SNK vs. Capcom: Card Fighters Clash series. She also appears as a playable character in the crossover tactical role-playing games Project X Zone and its sequel, wearing her costume from Revelations, and in the browser-based social game Onimusha Soul (2013), where she was re-designed to fit the feudal Japan theme.
