I haven't really talked much about the villainess much have I? We'll here's a run down of her personality:

Real name: Kelsie Harriett Landers
Self deemed name: Kelsie Vin Callous
Back story:
As a child both parents became continuously financially deprived due to traumatic experiences with being sued for ridiculous things, eventually resulting in the family becoming homeless. They resorted to living in a junk yard, teaching themselves to build vehicles and other mechanical things out of pure scrap. At one point her father was killed by a falling piece of debris. Her mother was pregnant then as well, but they lacked the money to lay for medical services, so she died of childbirth and the baby also died shortly.
Kelsie was left alone and went insane, vowing to avenge her family and enslave the people for sueing her family, and renamed herself. Using her knowledge of machinery her family taught themselves, she converted the junkyard into a mechanical fortress. She then constricted a vinyl dress with combative features built in. She made an army of robots to carry our her commands.

Facial features: black hair with a green tip on her bangs sticking up and curling outward, a small beauty Mark next to her mouth, purple eyes due to installment of micro-electronic power giving chips, shorter than average height, usually wears her orange combat dress and red high heels, considerably attractive on a decent level

Likes: exercising, building robots and machines, cheese popcorn, roller skating, kidnapping Jeff just to make Beatrice mad, talking to herself

Dislikes: Beatrice (they met when Kelsie attempted to destroy a power plant and she arrived, hearing the commotion, and beat her up and stopped her), Jeff (she thinks his feminism is annoying), rotten socks, oranges, malfunctioning robots, broken zippers, walking on ice, people making fun of her hair

Little known fact: Kelsie enjoys watching Loony toons
