Found another...

Yet another character. Only this one is slightly different.

This character is named Velony and is the first character in the FNaPMD series to be a shiny Pokémon.

Velony’s Jumpscare in The Dark Dining Area in Chapter 1 when the power goes out.

Velony attacks in the dark and only in the dark.
