Image from Pinterest (Don't know much about FNAF T_T) Wait, this was supposed to be for personal use.

He usually wears denim shorts and a gray tank top at home. He has blue eyes and is handsome(?). The eldest son. He is incredibly tall.
The second son, 10 years old. He has slightly messy brown hair and blue eyes. He cries easily but can be quirky at times. He is smart(?) and quick-witted. He wears a gray striped shirt. He is handsome(???). He gets bullied by Michael. Male. He is capable of talking back (meaning he's not a total pushover).
Also called Liz as a nickname. Female with green eyes and orange hair. The third child and William's favorite. She loves soft-serve ice cream. She wears a red ribbon in her hair, a pink top, and a purple skirt. She is extremely cute and very, very energetic.
Male with brown hair tied in a ponytail. He is tall and handsome(????). He is a mechanical engineer but also a serial killer of children. He creates animatronics by killing people and putting their souls into the machines (headcanon). Estimated to be in his mid-to-late 30s. He is indifferent to his children, though he dotes on Elizabeth slightly more than the others. He is blunt and cold. He always wears a purple suit. (Headcanon) He has neat handwriting and speaks in a commanding tone. He wears a custom suit called Spring Bonnie (a yellow rabbit suit). He is the owner of Freddy Fazbear's Pizza. He is insanely tall(??).
He sits quietly watching a horror movie with Evan and Elizabeth.
He screams when a scary scene appears. "Gah!!"
He gets startled along with him. "Eek!!"

He grabs Michael and Evan's necks from behind rather than hugging them. "Do your homework."
He gets even more startled. "Aaagh!!!"
