Basically - Madoka Magica's ending features a few historical figures, including Jeanne d'Arc and Cleopatra, with their own designs. Those designs were tagged with non-qualified Cleopatra and Jeanne d'Arc on Danbooru.
Except.
Those aren't the only or last times these two historical figures were featured in Madoka Magica media, and in both of them the design changed radically.
Jeanne d'Arc later got her own spinoff - Mahou Shoujo Tart Magica, in which she generally doesn't look like this. However, her death scene right at the beginning of the manga uses a design closer to the OG anime's ending.
Cleopatra was just announced for the current PMMM gacha, Magia Record. Similarly, her design differs, but this time, there seems to be no indication of her using the OG anime one. Here's her trailer, and here her Magical Girl silhouette can be seen (magenta, 3rd from the left in the top row).
Basically what I'm asking is, should OG_Anime!Jeanne d'Arc and TartMagi!Jeanne d'Arc; and OG_Anime!Cleopatra and MagiReco!Cleopatra have separate chartags? And should the OG anime versions be tagged with the historical person unqualified tags?
EDIT: It seems like Cleopatra from the OG anime is tagged as Cleopatra (Madoka Magica). My question still stands.
EDIT2: Turns out that the new girl is a separate character who just lived in the same times as Cleopatra. That just leaves the question regarding Jeanne d'Arc.
