Chart of who has Skins/Alts. Which Nikke do you want to get a skin/alt next?
Notes:
- For D and Scarlet, only their alt form got a skin.
- For Eunhwa, Vesti, Emma and Mihara, their alt form only appears in the story and is not currently playable, but still I counted them as alts for this list.
- Did not include alt units, R Units (Mass Produced Nikkes) or collab units.
