It's time for the second TV Tropes Halloween Avatar Contest, theme: cute monsters! Details and voting here.
A character who is often forgotten by other characters sometimes to the point that they forget the character even existed. The character might be a Ridiculously Average Guy
who's so unremarkable and ordinary that they seem to blend in the background. The character could be a minor villain or mook that the heroes defeat early on in story who returns to find out everyone forgot who they are. A character that has a low-key job or role in the cast might also be easily forgotten. Some characters even have a type of power that causes everyone to forgot who they are.
Other people who want to remember a person like this may leave a Note to Self
to help them remember.
Please note that this trope is for in-universe only. Meta examples would go in Out of Focus
Anime & Manga
- Kagero Usui in Sayonara, Zetsubou-Sensei is technically the Class Representative, but has a property to slip away from other characters' memories because his only distinctive feature is his Prematurely Bald head—which he tries to hide most of the time.
- Axis Powers Hetalia has Canada, whose interactions with other characters often involve them forgetting who he is or that he exists and/or mistaking him for his more outgoing brother America.
- In Jewelpet Sunshine, there are three examples. One is Nejikawa, who's forgotten by his classmates at least once. In one episode, he comments that he has become "as invisible as Yaginuma", which suggests the same thing of this character but is never really proven due to his limited screentime. Finally, there is Katori, who's so small, characters keep forgetting she's there.
- Only the main characters remember speaking with Fuuko Ibuki in CLANNAD and even they start forgetting her later in the series. Justified as she is a spiritual projection of a girl in a coma.
- In Manga/Eyeshield21, Tetsuo Ishimaru is so forgettable that other teams completely forget that he exists. He even breaks the fourth wall to comment on it.
Live Action TV
- In Jennifer Lynn Barnes' YA novel Nobody, this is the "power" of Nobodies. They are so forgettable that when they go rogue the group that controls them has to set a timer to periodically remind them who they're looking for.
- Kragar from the Vlad Taltos series is so utterly forgettable that he can be standing in the room and no one will notice him, and will forget he's there minutes after speaking to him, even if he hasn't moved.
- Harry Potter: Peter Pettigrew aka Wormtail is only known as the quiet, unassuming guy in James Potter's Marauders, and the fact that he was supposedly killed by his friend Sirius, but nothing behind that. This trait is what makes him trusted with the Potter family secrets by Sirius, and it also makes nobody suspecting him when there's a rumor about a Death Eater spy in the Order of the Phoenix.
- Alexander Throttlebottom in Of Thee I Sing is the Vice Presidential nominee running with John P. Wintergreen. He's so forgettable that he has to sneak into the White House with a tour group because no one remembers who he is. (Back in the 1930s when the play was written, the VP position was notorious for its lack of notability.) He does get remembered in the grand finale, as he's needed for a Pair the Spares moment.
- Luigi suffers from this problem in some Mario games. In the DS remake of Super Mario 64, for example, the Toads openly admit in front of him that he's nowhere near as memorable as his brother Mario is.
- Winston Payne in the Ace Attorney games. Once feared as a rookie killer, Payne is now so unremarkable that most of the other characters forget who he is. When Detective Gumshoe mentions him to Miles Edgeworth, one of Payne's fellow prosecutors (who Payne insists he mentored when Miles was younger), Edgeworth assumes he must be one of the janitors.
- Happens often in Scandinavia and the World. Denmark always forgets about his room mate The Faroe Islands until he owes him money, and Norway seems completely oblivious to Kven even when he's right in front of him.
- The 70-Seas side-story "forgettable" is centered around such a character. In a bid for attention, he commits a burglary and gets arrested, but not even that works, and he's released despite dropping the stolen diamond in front of the cops.
- This is eventually Lampshaded in As Told by Ginger. Two of the characters select recurring background character Noelle to test their vanishing powder on, as she wasn't significant enough for anyone to miss. And then later Subverted when it's realized Noelle was actually a cool (by the characters' standards) Cloud Cuckoo Lander and goes on to be an Ascended Extra with a substantial role.
- It's a running gag on Futurama that Scruffy has to keep reintroducing himself to people. "I'm Scruffy, The Janitor" has become his Catch Phrase.
- South Park: In the episode "The Last of the Meheecans", the boys play a Border Control role play game, and eventually the Mexican side claim victory. It takes a long while until Cartman realizes they forgot about Butters (and even then only because he can now still win as the Texan side). As the others wonder how this happened, Craig Lampshades that Butters is a rather easy to forget person.
- The Simpsons:
- A Running Gag on the show is that Mr. Burns always forgets who Homer is.
- Homer is often forgetting about Maggie. Sometimes he just refers to her as "the baby", sometimes he forgets about her completely.
