Use them. Especially Four. NOTE: The reason why the Two has no face and limbs is because they never appear with their face and limbs in the video. (There's another version of Two with them) NOTE 2: Nine is X because Four is a square, so it would make sense for the X character to be a square too, so I chose him to be Nine. NOTE 3: Four has 2 versions. The XFOHV Four and the BFB Four.
