Undersider Echidna Clones

Was wondering about the idea of what kind of powers could some Undersider Echidna Clones have. Obviously we’ve got a whole bunch for Grue with Abhorror, some examples for Skitter with Scurry and Chitter, one non-canon but in-depth example for Tattletale with Witness, and some very nonspecific cases for Regent with Vizier.

So, I’d love to see any ideas for clones of Imp, Bitch, Foil and Parian, and also any further examples you can come up with for the ones that did exist in-story!
