Sine is a character from the Blood On The Battlefield series made by Deviantart user MajorKrystalFan. She acts as one of the minor villains in the story.
Model #2150 - Sin(e) is one of the minions of Brain. She is the newest model/youngest sister of the Trigonometry Trio.
Her hair is pink and tied into pigtails. Like her sisters and Quarantine, her face is heavily branded.
Like the rest of the Trig girls, she wears a blue & black leotard, wristbands and knee-high boots.
Sine is the most emotional of the Trig girls. She aspires to be the most human out of the others, even so much as practicing her emotions on her opponents.
Ergokinesis - Sine is able to manipulate energy through her hands and fingertips.
Sine's fighting style is based around her whole body, using every limb to her advantage as well as her emotional prowess.
