Hopefully my nominations should be pretty straightforward as they're all canonical tags and most have (TV) in their tag but I just wanted to clarify that The Borgias (2011) is the showtime TV show: https://en.wikipedia.org/wiki/The_Borgias_(2011_TV_series) and not the Canal+ one. Preacher is the TV show; https://en.wikipedia.org/wiki/Preacher_(TV_series) not the comic. Also despite the tag brackets, I'd like to nominate Tatia (Vampire Diaries) under The Originals (TV) as she is only ever mentioned in The Vampire Diaries but she is actually portrayed on screen in The Originals.

Here are some character bios for the ones AO3 hasn't auto-accepted;

The Borgias: Giulia Farnese -- http://theborgias.wikia.com/wiki/Giulia_Farnese
