Cross melting aura
A character so evil/unholy, holy artifacts are twisted/destroyed by their mere presence.
conjuring 2: Valak passively turns the crosses meant to guard against him upside down (een though that would still make them holy as an upside down cross is a saint Peter's cross but eh).
hellraiser 3: Pinheads mere presence is able to slowly erode a church while inside him. The church eventually implodes after Pinhead mocks the stigmata.
