Shion makes an appearance in Namco × Capcom, when she, M.O.M.O., and KOS-MOS appear in the middle of Shibuya during a series of dimensional disturbances, in time to help the main characters against a Gnosis attack. In the game, Shion is paired with MOMO as a single unit. Bandai has released Shion figurines as part of the Xenosaga Legend toy set.
