Less known Disney villains

I'm sorry if anything I write offends people, but the the coachman from Pinocchio, Charnabog from Fantasia, and Mr. Dark from Something Wicked This Way Comes are good villains.
The coachman is responsible for a place call Pleasure Island where he gives children beer, drugs, and food. While under the scene, he turns them into donkeys and a life of slavery. Then you add a line like "they never come back... as boys!" that should send bright red flags about how wrong that sounds.
Next, the monster Charnabog is big, evil, and very powerful. He can summon hundreds of monsters, open the jaws of hell, and revive people. That alone can make him stronger than dark side, maleficent, or Hades.
Finally, Mr. Dark may not be as powerful or big, but he is smart, entertaining, and a strong manipulator. He is able to use the darkest dreams to enslave people, summon animals to kill his target, and turn a whole town against different heroes.
If I am wrong or if you want to add something, you are free to do so.
