Two different versions of the same character appearing together in the same image. Example: Saber & Saber Alter.
Each persona counts as a separate character, so don't use solo, 1girl or 1boy with this tag.
Do not use this tag for reference sheet, variations, multiple views, or other depictions of the same character from multiple points of view.
If the instances of the character are identical, use clone instead. If a character is meeting their older or younger self, see time paradox. If more than two personae are in one image, see multiple persona.
