Flapper

 is a member of the hero team Advance Guard.

Appearance
In costume, Flapper wears a short dress over leggings, as well as long sleeves containing panels that form them into wings. She has a paneled mask designed in a wing pattern.

While using her power, Flapper's sleeves become long wings, capable of flight.

Abilities and Powers
Flapper has the ability to alter and extend her clothing. Using her power, she can form the sleeves of her costume into large wings that she uses to fly by riding air currents. She can also alter her wings to give them 'middle fingers' that she uses to attack from above. Her wings can be used as barriers to block enemy fire.

Early-Ward
Flapper participated in the fight between Advance Guard and the Hollow Point villains. She questioned Mayday about his cold treatment of Looksee.

Post-Fallen fall
Alongside Spright and Shortcut, she went after the villains Trial and Error. Though Breakthrough was called in to assist, due to the villains' powers proving problematic, they were forced to retreat. With additional backup, Flapper and her teammates were eventually able to apprehend Trial and Error.

Post-Goddess' Takeover
With Spright and two members of the Lone Wolf Pack, Flapper went after the villain pair Eclipse Arc; the villains retreated, and the heroes did not pursue.
