On 50/20 mode of "Ultimate Custom Night," Dee Dee will be replaced by a darker, ghostly version of herself as X.O.R. (commonly referred to as Shadow Dee Dee). After vanishing, all of Dee Dee's summons will appear one at a time in a fixed order (going from Shadow Bonnie, Plushtrap, Nightmare Chica, Bonnet, the Minireenas and finally Lolbit). She is completely resistant to the "DD Repel" power-up, meaning 50/20 mode must be completed with all of Dee Dee's summons as well. This version of Dee Dee can also appear in normal modes, though this happens very rarely.
