Secret of the Mimic ( FNaF x Dark Shadows)

Gregory, Glamrock Freddy, and Roxanne Wolf mysteriously end up in the abandoned, ruined, and now rumor-ridden animatronic factory Murray's Costume Manor, owned by the reclusive inventor Edwin Murray.

Left alone in a battered state for years, the Mimic seeks revenge...
