Ponytail is a stick figure character in xkcd, and the second most used female character, although she is far less used than Megan. She is distinguished from other characters by her blonde hair which is set up 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 and Sarah in 84: National Language. However this last comic seems to be about the real-life friend of Randall.
Ponytail was originally mainly a filler character, showing up when two females were needed or when a large group of people are present. But she has become more and more used, also without for instance Megan present in the comic. She is rarely used more than once in a comic (as opposed to Cueball), but there are two distinctly different Ponytails in 673: The Sun, although they do not appear in the same panel.
She seems to be less typically nerdy than Megan. In many comics where she has a specific role, she tends to have more educated roles such as in 451: Impostor as an engineer and she has also appeared multiple times as a doctor in a coat in 883: Pain Rating, 996: Making Things Difficult, 1713: 50 ccs, 1839: Doctor Visit and 1840: Genetic Testing Results. Her doctor persona is also the depiction for Randall's wife's doctor during her battle with as chronicled in 1141: Two Years.
Oftentimes, she is used as a police officer or security guard, usually with a male police officer as her counterpart, like in 1018: Good Cop, Dadaist Cop, 1113: Killed in Action, and 1251: Anti-Glass.
