I've read a lot of Fanfics, and only encountered one that was a male. So yeah, I'm pretty bad with description, but I'll try my best.
Ben Depth only visited the place when he was younger and promised Bonnie, Foxy, Freddy that when he come back to them, he would become their 'wives'. With his friend the night watcher, Jeremy, trying to save him from the 'horrifying' fate that he made. The animatronics never forgot their promise with him and battles against his friends to reach him.
~so how I do?~
