Tybalt
The "King of Cats".
Where is he from?
Tybalt is a recurring character and love interest in Seanan McGuire's series of urban fantasy novels, October Daye. The series has never been adapted into anything, so this is an entirely literary reference, and unlike series protagonist October who at least appears on the covers of the books, Tybalt doesn't seem to have any offical art of him at all. I found this piece of fanart but couldnt find who drew it, so the version that appears in GND might actually be the most cannon version anyone has ever done.
