It's very difficult to find villains around nowadays....
while he's not strictly a villain, we did just see Beast at EPCOT in France down near the water. He came out when Belle took a break and then she came back and joined him.
And again, not a "true" villain, but pretty naughty nonetheless -- you can see Stitch several places, including breakfast at Ohanas and DHS.
The wicked stepmother and step sisters have been at 1900 Park Fare when I've been there for dinner (not a very good dinner, but good interaction)
