* Similarly, ''FanFic/TheEndingOfTheEndLoveAndToleranceEdition'' intentionally keeps Cozy Glow's past and motives vague to not conflict with the show's continuity before the events of the story. Despite giving a lot more focus and development towards the villains, her included. The author ''did'' publish a one-shot, "[[https://www.fimfiction.net/story/461656/an-interview-with-cozy An Interview with Cozy]]", that's said to be in continuity with this story and does have her give an in-depth interview revealing her motives and thought process behind her prior scheme... ''but'' that story also [[UnreliableNarrator leaves it ambiguous how genuine she was being]].
* Fanfic/SunsetsIsekai: Applies to the Rarity who is Sunset's business partner. We know she had a bad relationship with the Spike from her home universe (at least it might be. This was mentioned in the very first chapter, even before the Isekai had been set up.), that her original form involved horns, and not much else.

* Rin Satsuki of ''Webcomic/TouhouNekokayou'', who was DummiedOut of the VideoGame/{{Touhou}} game where she was supposed to make her debut. In this comic, she appears to have some sort of past in which she had a conflict with Yukari; the mystery is maintained through carefully ''not'' using AsYouKnow. WordOfGod has stated that all would be eventually revealed in an associated FanFic.

* Smith from Podcast/CriticalHit has this problem. Neither Rob, his player, nor Rodrigo, the GM, have revealed how much he knows himself, or what exactly is the cause of this.

* Podcast/WelcomeToNightVale: ''Cecil.'' Even after two episodes that actually focused on his past (Cassette and [Best Of?]), we still know very little about it. We know he had a mother and brother- they disappeared at some point when he was a teenager, and we still have no idea what happened to them, and ''Cecil can't even remember them.'' Then, a flickering movement that teenage Cecil was seeing out of the corner of his eye attacked him from a mirror- and that's it. That's all we know. Then [Best Of?] came around and raised even more questions with the revelation that Cecil is several hundred years old and has been around since ''before radio.''

* Creator/TommyWiseau's past is virtually unknown. He claims to be from New Orleans, but his accent suggests somewhere in Eastern Europe. He's also independently wealthy, but the source of his wealth is unknown–he claims it was from selling leather jackets. Several people who worked with him on ''Film/TheRoom2003'' have proposed theories, and one--who claims to have seen something official from the US government regarding his immigration--said that the truth [[{{Tearjerker}} was the saddest story he had ever heard]]. He did not share the details.

*** The Wolverine from ''ComicBook/UltimateXMen'' seems to have done a lot less globe-trotting, spending most of his time between World War 2 and the 90's imprisoned by Weapon X.
