Clapper

From the White Wolf Wiki, the most complete White Wolf reference

Clappers are a type of Spectre seen in Orpheus. They are used to capture spirits to be taken to Spectral hives.

Clappers are named for their form: two giant, clawed hands joined at the wrists and giant, bat-like wings that grow from where the wrists meet. Though they can do damage through their claws, they are not very powerful, and will choose to drop a troublesome target rather than be damaged by them. They belong in the category of Spectres that were never human. They are primarily associated with the pigment poisoning tragedy in Shades of Gray.
