I guess it's always been kind of a tradition that the villians would be played by human actors. In Christmas Carol, the Scrooge character isn't necessarily a "villian" but I guess it works.
Really, it could be Statler and Waldorf (Marley & Marley) that seemed to be the villains on account they led Scrooge to his wrong doings? So...Muppet Christmas Carol....I doubt has an actual "villain"...
The Muppet Movie - Doc Hopper, Crazy Scientist (Mel Brooks), & Frog Killer
The Great Muppet Caper - Charles Grodin (real name) & 3 Girls
The Muppets Take Manhattan - The Con Artist (Man from film '9 to '5) and the
city of New York could be considered, thus it
broke the gang up and caused Kermit to get
hit by a taxi and get amnesia!
Follow That Bird - Miss Finch and Sleaze Brothers
The Muppet Christmas Carol - Marley & Marley - Scrooge (kinda)
Muppet Treasure Island - Long John Silver (Tim Curry)
Muppets From Space - Jefforey Tambor (Government Man) - Edgar?
Elmo In Grouchland - Huxley (Mandy Patanka)
It's A Very Merry Muppet Christmas Movie - Ms. Bitterman (Joan Cusack)
The Muppets Wizard of Oz - Jefforey Tambor (OZ)
The majority have been all human actors. Although, in Muppet Treasure Island and Oz films some minor Muppets were casted as villains, such as Crazy Harry!
I've also noticed that the human characters usually have an unknown or new Muppet as their sidekick villain. Then, they later turn for the better or are weasiled into the job! That tradition slowly started in
The Muppet Christmas Carol where Statler and Waldorf worked with Scrooge, Muppet Treasure Island - the Muppet pirates who worked for Long John Silver - Sweetums - who later helps Kermit and Sam the Eagle during sword play,
Muppets From Space - Bo Bo the Bear (One of my favorites) as Edgar's (Jefforey Tambor) assistant, later helps the Muppets in the end.
Elmo In Grouchland - The Bug that helps Huxley
It's A Very Merry Muppet Christmas Movie - Pepe (Tricked into job to ruin the Muppet theater.)
The Muppets Wizard of Oz - Bunsen, Scooter, Sam the Eagle, and Scooter - who were're really villains, just worked for them.
