- The Fans in With Strings Attached. Actually aliens who describe themselves as “kinda lizardy, kinda birdy,” they use default faceless humanoid computer avatars when dealing with the four, and they're never even shown to the reader. Hints of their true appearance come out in their dialogue, e.g., “Ow! My tail!”
- Except Jeft, whose brief description by the other two suggests he is a fat Grey with poor hygiene.
- Also the god Ardav, who is a bland sexless humanoid who cannot be remembered except as a faceless mannikin.
- Baron Zemo is this in Child of the Storm, his classic purple mask being attached to his face at all times. His protégé, Jason Todd a.k.a. the Red Hood wears a similar mask, but his actually comes off.
- In the Ben 10 fanfic Hero High: Sphinx Academy, Original Character Spec Masters (as well as his entire family who serve the Tempus) all wear one way mirror masks. It is supposed to reflect the person they serve as a way to prevent abuse as well as to prevent relationships between the two families.
- In the Kung Fu Panda Alternate Universe fic A Different Lesson Chao doesn't reveal his face until near the end.
- In the Lyrical Nanoha/Slayers AU crossover Blood That Flows, during the REVOLUTION arc, the kids meets an informant of Lyos, a sorceress named Nila Vesnire who rarely speaks and her face obscured by the cloak she wears.
- Oblivion's Shadow is this in the Pokémon Mystery Dungeon fic Brave New World.
- Elliot in Calvin and Hobbes: The Series, at least initially.
- Also, the MTM, who is a CD player often described as an "electric pancake".
- The illustrations of the Grand Elder in the Homestuck fic Cultstuck avoid showing his face or the tips of his horns, although there’s a brief description of his face in chapter 13.
- The Cult of The Signless wear hoods to hide their faces. An urban legend called "The Faceless" was based on them, although taking a rather more literal definition of the term.
- Ebony Dark'ness Dementia Raven Way vs. Canon: The Anonymous, who always keeps her face hidden, even from Missy.
- In the Disgaea fic Fail to the King!, Monty's helmet covers his face. Once that helmet gets knocked off, he's promptly killed and transforms into a sword.

- Zig-zagged in Origins, a Mass Effect/Star Wars/Borderlands/Halo Massive Multiplayer Crossover. At one point, some of the heroes need to become this in order to sell themselves as mercenaries enabling infiltration of an enemy base. Many members of the Clone Army wearing full-body armor qualify as well, but since it's known what the original clone looks like, the trope doesn't exactly play straight.

- The Watcher and the Deliverer in the Warrior Cats fanfic Golden Dawn: Lost Sunrise. They aren't actually wearing masks or concealing their faces, but those are concealed from the reader by a lack of description of their physical appearances. Why? Because they're both Clan cats who appear in the story (the Deliverer in particular is confirmed to be one of the she-cats in the first chapter), and their true identities are said to be big twists. As well, Aurora, a young she-kit the Watcher is preparing to kill at the end of the prologue, never gets her appearance revealed either.
- In Mega Man: Defender of the Human Race, Mr. Black is this at first, and the Conduit is also this.
- This Bites!: Subverted; for the first twenty-one chapters and the Christmas Episode, the author gives no description what Cross looks like aside from his clothes, but he did have a picture before the story stated that he was around 6' (Chapter 26) with dirty blond hair (Chapter 22).
