Possibly Needs a Better Title, almost certainly Needs a Better Description, Rolling Updates underway.
But most of all Should We Have This??
See here for the original YKTTW discussion. Trope idea origionally from this (non-TV Tropes) forum discussion, including this. Please forgive me if I've screwed up the examples. If I did, please explain what I need to do to fix it, thanks.
I'm thinking let's limit this to kid vampires (appear to be preteen at the oldest) only. I may or may not want to open a new one about teenage - looking Lady of War vampires.
In both Real Life and fiction, it's normally expected that children of dangerous creatures will be less dangerous than their parents, particularly if said parent is a Mama Bear. However, when it comes to vampires, this isn't necessarily the case.
This character type trope, as currently defined (which is what I'm looking for consensus on), consists of three elements that the character must be:
A vampire. Monstrous species that are called something else but are treated like vampires (must drink blood, killed by a wooden stake, etc.) probably should also count.
In Warhammer tie-in fiction by Kim Newman, Melissa d'Acques. In the short story "No Gold in the Grey Mountains", a group of travellers including an innocent 12-year-old girl is being stalked by an ancient bloodthirsty horror; the twist at the end, as you'll have guessed from the context of this example, is that the ancient bloodthirsty horror and the apparently-innocent apparently-12-year-old are one and the same.
The Doctor WhoMissing Adventures novel, Goth Opera, has a vampire baby, which was turned when it was too young to walk, so it flies everywhere instead.
In the Twilight novel, Breaking Dawn, it's revealed that there was a great disaster several centuries back when turning toddlers into vampires was all the rage. It did not end well.
In Blood Alone, Misaki is actually not too much older than she appears to be (looks about 13) and right now most of her vampire personality is repressed but watch out when it takes over. A male version is Higure, who is a full-fledged vampire and will eat your face if he doesn't like you. Mostly he's pretty nice, though.
From Chibi Vampire, Elda Marker. She looks 16 despite being a grandmother, and despite the fact her bite doesn't kill (instead, it causes people to fall out of love, but usually only temporarily), is feared by vampire hunters and other vampires alike. In fact, all the vampire characters in the series were very cute children, and more than capable of holding their own in a fight.
In Rosario + Vampire, without the crucifix to keep her darker side in check, shy and tender Moka is the most lethal student at Youkai Academy.
Her younger sister and resident Yandere, Kokoa, also qualifies.
In Buffy the Vampire Slayer, Darla is the first character we see in the TV series. An innocent schoolgirl pressured by her boyfriend into sneaking away and making out. Really a vampire, Dragon to the Big Bad.
From Anita Blake, Nikolaos looks like a 14 years old girl. But she's an evil sadistic Really Sevenhundred Years Old Vampiress who is the master of the entire city of St. Louis and runs it with a sadistic iron fist, trying to kill the heroine on multiple occasions in the first book and later Anita kills her.
From Adventure Time, Marceline, who despite being the "born vampire" type, is over 1000 years old. She apparently can turn into all sorts of monsters, and can become invisible at will.
Five hats means that five tropers think it is ready to publish.
You are saying that you think this draft is ready to be published. That means the description is not ambiguous,
it doesn't duplicate an existing trope, there are at least three examples, and the title makes sense.
Is that what you meant to do?
You are saying this draft has a ready-to-publish hat it does not deserve and you are taking it back.
