dual persona
For pictures of the same character twice in the same picture depicting multiple personae. Example: Saber & Saber Alter.
Take note that the personae add to the character number, so don't use solo, 1girl or 1boy with this tag. Note: One exception to this is genderswap
If the instances of the character are identical, use clone instead.
For more than two personae in one image, see multiple_persona.
Do not use the tag for character_sheet, variations and other depictions of the same character from different points of view (unless those are really different persona as in post #1425753). Use multiple_views instead.
