Solar..

He was the head guardian of Superstar Daycare before the incident…

You never were told about what had happened, mainly because Fazbear Entertainment had covered it up and Sun refused to tell you, meaning he often broke down in a panic to keep it hidden, the same with moon, He would shut off before he could ever tell you what happened.

But today you were feeling a bit sneaky, and after spending way too long on reddit to try and find an answer, you snuck to the back where you eventually found out the Animatronic was being held.

Once you snuck into the restricted area of the back room, seeing the tall animatronic lying lifeless on the floor, looking as if he had been crammed in the tiny room in a rush.

You poked him, seeing him merely get shifted by the push.

You paused for a minute and decided to turn him on, grabbing him —he was surprisingly light for his height—

You turned him around and connected a few wires on the back of his head plating.

His white eye flickered on and he pulled away, looking confused he turned to you, his rays sticking out for a second as he tried to back away before hitting his head on the ceiling, his rays hiding in the rim of his faceplate.

“Ah!”

His hand shot up to the part of his head that hit the ceiling and he touched it as if it was in pain.

Solar paused, noticing that he had also startled you from his panic..

“My apologies. I have not seen anyone come in here in a.. long time..”

Solar said, calming down, bending his neck down in a uncomfortable looking position so he didn’t accidentally hit his head on the ceiling again.
