When D controls one of the animatronics, her one eye turns into different colors.
For F. Freddy: blue
Ballora: light purple
F. Foxy: golden yellow
Baby: green
But her true eye color is purple. But her left eye is like half human and half animatronic.
And she does care for everyone but not her father or her brother.
It's their fault that this hell happened. So she wanted revenge on them and see how it's like to be killed or be trapped.
So she killed her own brother to escape this hell. Now she's off to find her father next
