DD is able to add characters you have not selected into your game, as well as increase the level of difficulty of an already existing character in your game. She can add any character from the roster, as well as her own secret roster, which is not available to the player.
Dee Dee's invisible roster includes:[]
There is also the possibility that the "[A new challenger has appeared!]" message will not show at all. This simply means that no new characters were added, and that either nothing has been changed, or an already selected characters difficulty has been increased.
“She appears at random and can add a new animatronic to your game. The animatronic added will not be announced, so you will have to quickly look at your cameras and other systems to find out who it was! Dee Dee also has the potential to add one of three characters not listed on the character select screen.” — Character Guide - Ultimate Custom Night. June 15, 2018.
Appearance[]
DD is similar looking to that of Balloon Boy and JJ, resemblant of an actual human, though still obviously an animatronic. She is actually a recolor of JJ's FNAF World character model, though her shirt only adorns one button, and the ball atop her cap is sized up. She wears purple pants, a pink and yellow shirt, and a propeller cap of the same colors. She has green eyes and peach toned skin.
XOR[]
XOR is an alternative version of DD, which is guaranteed to spawn in 50/20 mode, and has a rare possibility to spawn outside of 50/20 mode as well. Her appearance is a completely monochrome version of DD with backed out eyes, the only color apparent being the red ball on top of her propeller cap. When she spawns, a distorted version of DD's song will play, and she will continue with her normal behaviors. The only real difference is that she will only spawn characters from her invisible roster, and at a more rapid pace.
Dee Dee's alternative appearance, XOR.
“I named Shadow Dee Dee X.O.R., and I'm not sure why. But like with most of the other characters in this franchise, whenever I'm making them, the name immediately comes to mind. It doesn't mean anything but that's the name of Shadow Dee Dee.” — Scott Cawthon, An Interview with Scott Cawthon - The Creator of Five Nights at Freddy’s[1]
External Appearances[]
Dee Dee originally appears in the 2016 RPG, FNAF World, but is only an NPC, and is not playable. However, she did have a small fishing minigame, based on the title of her small area; Dee Dee's Fishing Hole.
