This trope is what results when a character has a particularly large number of siblings, and they're the only boy/girl. This can often result in the character hoping and praying for a sibling of their gender, Parental Favoritism in either the character's or all the other's favor, and the character feeling either superior or inferior to the rest. More often then not, said character is either the youngest or the oldest of them all.

Subtrope of Massive Numbered Siblings. See also The Smurfette Principle and I Have Brothers

Highly expect Annoying Younger Sibling and Big Brother Bully to come into place.

Examples of Outnumbered Sibling include:

Anime and Manga

  • Sister Princess. An orphan named Wataru Minakami discovers that he has 13 sisters, one of whom is The Mole, and not actually one of his sisters.
  • Quatre Raberba Winner of Gundam Wing is the youngest child of his family and has twenty-nine sisters. The catch is that all of his sisters are test-tubes babies due to difficulties with childbirth in space among early space colonists; Quatre was the only child born naturally, although his mother died during childbirth and the fact that he wasn't artificially reproduced was kept secret from him. However, Quatre is shown to dearly love his sisters and it is the near-death of his favorite older sister Iria (along with the death of his father) which drives poor Quatre over the edge.

Comic Books

  • Hope O'Dare from Starman has four brothers. She and her brothers are all cops and it's mentioned that she is the one everyone is frightened of.

  • Roberta from Now and Then had three older brothers and no sisters. The brothers are only briefly seen but it explains why she's such a tomboy.
  • An Our Gang short illustrates this trope with a hint of Values Dissonance. Mickey is picked on by his two sisters and hopes that the baby his mother is pregnant with is a boy. Somebody tells him that every fourth child in the world is born Chinese. He's upset by the idea of having a Chinese younger but eventually comes to accept it. Unfortunately from his point of view, his mother gives birth to another girl.

  • Ginny Weasly of the Harry Potter series is the only girl in a family of seven children.

  • In the Vorkosigan Saga, Ekaterin has several older brothers and no sisters, and this is mentioned as being common among Barrayarans of her generation as the result of newly-obtainable sex-selection technology. In contrast to all the tomboyish examples of this trope, she specifically mentions this as being part of the reason why she's a Shrinking Violet.
