The Demon Hipster Chicks are a group of female demonic entities that serve the first of Ramona Flowers' evil exes, Matthew Patel. They are not independent characters but rather an extension of Patel's mystical abilities, either functioning as loyal demons under his command or as physical illusions conjured by his powers. Their entire existence is tied to his role as a villainous antagonist.

In appearance, the Demon Hipster Chicks are designed to blend demonic traits with a specific subcultural aesthetic. They possess bat-like wings, fanged teeth, slit eyes, and claw-like fingernails, marking them as clearly inhuman. Their attire consists of tank tops emblazoned with a star, mini-skirts, and dark pantyhose, which gives them the look of a particular urban archetype from the late 2000s. This combination of the monstrous and the mundane is a signature visual gag within the series.

Their primary role in the story is to act as reinforcements for Matthew Patel during his battle against Scott Pilgrim. In the original comic book series, Patel summons them to help him fight Scott and his friends. They attack by hurling fireballs at their opponents and are capable of levitating and flying through the air, making them agile threats in combat. Despite their supernatural advantages, they are ultimately defeated when Scott and his allies generate a Musical Shield to block their assault and then counterattack with a song about friendship and courage, which stuns both Patel and his minions. Scott finishes the fight with a single flying punch, causing the Demon Hipster Chicks to vanish.

In the film adaptation, the Demon Hipster Chicks have a very similar function but are given a few additional moments. They are summoned by Patel to aid him in his concert hall battle with Scott. In this version, they are responsible for accidentally vaporizing the opening band, Crash and the Boys, with a stray fireball, which adds to the chaotic and comedic tone of the scene. They also participate in a musical number, singing the song Slick alongside Matthew Patel. They disappear from the film when Patel is defeated by a cymbal thrown to the head. In the movie, all of the Demon Hipster Chicks were portrayed by a single actress, Christine Watson, who performed different takes for each individual chick to give them subtle variety.

Their role is expanded in the video game Scott Pilgrim vs. the World: The Game, where they serve as an integral part of the Matthew Patel boss fight. As Patel takes damage, he summons the Demon Hipster Chicks to protect him, making him invincible until they are destroyed. Later in the battle, he summons more powerful versions that shoot unblockable fireballs at the player, increasing the difficulty of the encounter.

The Demon Hipster Chicks have no personal motivations or independent character development. Their entire purpose is to serve as obstacles for Scott Pilgrim, functioning as minions that highlight the magical and video game-inspired nature of his world. They are an extension of Matthew Patel, and their key relationships are defined solely by their subservience to him and their antagonism toward Scott and his friends. They do not have notable abilities beyond flight, fireball projection, and combat assistance, all of which are standard for their role as low-level supernatural enemies.
