Funny how there's the Fate/Apocrypha tag even though just Vlad shows up there (and Gilles I guess, but I don't remember if he appears in his caster form), but not Fate/Zero, Fate/Extella Link or any other works that Gilles appeared... I don't know if it was discussed before, but if the majority of characters in one image are just from Grand Order, just Fate/Grand Order should be enough.

Gilles appeared in his Saber form, with a slight cameo of his caster versions fish eyes, but he wasn't actually there though, it was a fake created by Shakespere's "The Globe" Noble Phantasm, but since The Globe is able to perfectly replicate people for the sake of the performance, it was practically a 1:1 replica of Saber class Gilles to the point where Luminious Eternalle recognized him as a worthy user.
@Ghost_H Based on howto:copyright, "On Danbooru, the term "copyright" means "the anime/game/comic/movie/etc from which a character originates"". So be sure to tag Fate/Zero when you see a pic with Caster Gilles in it in the future.
