|First appearance||84: National Language|
Ponytail is a stick figure character in xkcd. She is the second-most common female character, though far less common than Megan. She is distinguished from other characters by her blond hair arranged in a ponytail. Like Cueball and Megan, she doesn't necessarily represent the same character from comic to comic.
Ponytail doesn't have a recurring name like Megan or Rob (for a few instances of Cueball). But a few times a Ponytail character has been given a name used only in a single comic. For instance, she is called Joanna in 322: Pix Plz, Sarah in 84: National Language (which may be about a real-life friend of Randall), and Doctor Adams in 1954: Impostor Syndrome and 2527: New Nobel Prizes.
Ponytail was originally mainly a filler character, showing up when two females were needed or when a large group of people is present. But she has appeared more and more, including without (for example) Megan present in the comic. She is rarely used more than once in a comic (as opposed to Cueball), although there are two different Ponytails in 673: The Sun in different panels.
In 2040: Sibling-in-Law, she was used to describe Cueball's sister in a quasi-family tree; however, other Ponytail characters were used in the same strip.
in 1018: Good Cop, Dadaist Cop, she says she has small bones.
Ponytail has appeared multiple times as a doctor in a coat, and she also depicts Randall's wife's doctor during her battle with cancer as chronicled in 1141: Two Years. For a full list, see Category:Doctor Ponytail.
