• Saki Omokane appears as a helper character in the Capcom fighting game Marvel vs. Capcom: Clash of Super Heroes and a playable character in Tatsunoko vs. Capcom: Ultimate All Stars.^[6] Her main weapon is her machine gun, though this makes her physical moveset limited. Her ending has her having tea with the rest of the female characters in Tatsunoko Vs. Capcom: Cross Generation of Heroes (Roll, Jun the Swan, Morrigan, Doronjo, and Chun-Li). Saki starts explaining about her world and its mechanics, while the rest of the girls remain clueless about what she's talking about. In Ultimate All Stars, she helps save the twisting dimensions and soon finds that the reason she fights is to protect the friends she made. She then prepares to protect her city from a rampaging Hauzer. She is voiced by Yoko Honna. While she does not appear in Ultimate Marvel vs Capcom 3, one of Jill Valentine's alternate colors is based on Saki.
• Saki also appears as Capcom character card C119 in the Neo Geo Pocket Color game SNK vs. Capcom: Card Fighters Clash. She comes with a special ability called "Stand-By", which is triggered once she enters the ring (field of play) and allows the player to pick one card from his deck and shuffle the rest, while placing that card on top of the deck to be drawn on the next round. Another character, Linz, is depicted on Action card A42, called "Pester", which allows the player to put three of the opponent's pile cards among his/her discarded (out of play) cards.
