Scarlet is a transgendered prodigy that seems to be under the care of Mr. Vertical.
Scarlet is like a normal female prodigy except with a few obvious differences along with her being bright red. She has a TV for a head which usually can change faces and use emotes. It does have prodigy horns too. Scarlet wears white gloves with puffs at the opening along with grey sock looking clothes for her feet which have puffs at the opening. On her chest, she has a core which has a red bow tie attached.
Scarlet doesn't know anything of her childhood. She does remember being found by Mr. Vertical and being brought to the hospital which is where she got her TV head and core. Scarlet also used to be a male until deciding to become a transgendered female. While she lives in her house which was made for her, Mr. Vertical takes care of her like a father figure while also being like friends.
Scarlet seems to just wander around the city and then eventually go into her own house.
