Connie the Coyote

Connie is a lifeguard animatronic originally from the first FNaF location, a scrapped project from a forgotten pool area plan. The name of the soul inhabiting her is Thunder, and together they use They/Them pronouns. Connie killed Thunder because she was envious that she got to do her job and talk with people while she rotted away, a discarded thought. Since Connie was created and unfinished, she is free to roam and do what she wants unlike the other animatronics controlled by William. 

Now they work together to save children from William and the other animatronics, similar to Glamrock Freddy in SB.
