Frightguard has elected to simply cover up his rotting head with a motorcycle helmet. The rest of his outfit is made to match. He doesn't actually own a motorcycle or even a car though, so he still walks everywhere.

He avoids speaking at all to avoid giving anything away.

In slight disbelief that Dude keeps hitting on him. Not that he doesn't like it, he's just not sure what he's going to do when it's zombie reveal time. He's considering leaving the country or killing himself.

Each night Frightguard dies, crossing over to the spirit world in order to help Charlotte and the shadows set up the Happiest Day. Before the night is over he re-animates and has to keep Springtrap from taking him out again. On the last night, he'll be the one to light the candles.

In certain lighting, the visor seems like a gaping hole in his face, or the compound eye of some strange insect. Regardless, the other employees feel watched.
