Ahhh this will be organized better later, I just want to put these down for now. Anyways, here's just a list of headcanons I have for her!

• She is 5'2" (157.48 cm) and in her 20s.
• She has central heterochromia. The inner ring of her irises are green, while the outer rings are purple.
• Her hair is springy and ever so slightly translucent, almost like some sort of gelatin.
• Like her brother, she is a vampire. However, unlike her brother, she is very ashamed of this side of her and got very deep into alchemy so she could somehow find a way to transmutate herself & her brother into normal cookies. She actually has made decent headway as she’s managed to create formulas that suppress her own vampiric tendencies and characteristics, thus why she seems “normal” compared to her brother.
• Her laboratory is in a deep, expansive crystal cave. Although this would normally be too dark and isolated for Cookies to work in, even with lanterns, she feels much more at home and focused due to her vampiric instincts.
• She wears gloves to not only protect herself, but to cover up the alchemical burns she’s received from faulty experiments that she did when she was younger. She is embarrassed by these burns because she believes it makes her look as if she does not know what she is doing, so she nearly never takes off her gloves. Nothing is worse to her than admitting that she has made mistakes.
• Although she does genuinely care for her brother, one of the reasons why she dragged him out of the oven was so she could use him as a guinea pig for her transmutation tests. Unfortunately, he is a rather uncooperative test subject, as he prefers to relax and do whatever he wants all day inside of drinking gross potions and staying cooped up inside her dusty laboratory.
• She and her brother have quite the habit of puckering their lips. It’s something that they both picked up from each other, and happens most often when they are feeling annoyed or focused.
• She is a lesbian (duh) & a certified Man Hater!
• Although her brother may stand a head taller than her, she is technically the older sibling because she was created first. However, it would be easier to just call them twins, and the fact that she is older doesn’t stop her brother from teasing her about her height and calling her his little sister.
• She and her brother both have huge foreheads lmfao.
• Her drink of choice is wine, like just her brother's.
• If she had a human name, it would be Allison “Ally” Chemings.
