For a villain, that is a Muppet, yes, Uncle Deadly always takes the biscuit. (Mind you, anyone who takes a biscuit should be considered a evil villain). Other than that, I stick with my old assessment of Tim Curry for captain villain, followed by Rachel Bitterman (she just did NOT care about those Muppets that evil woman), followed by Nicky Holiday (And, yeah, well, in terms of accent Lady Holiday moved in very different circles to him, and if you know British you know how much our accents modify depending on circumstance).
