Dr. Facilier

Doctor Facilier is the main antagonist of the Disney film The Princess and the Frog.

The Princess and the Frog
He is a voodoo witch doctor and palm reader from Louisiana who tricks Prince Naveen into a fake palm reading and turns him into a frog. He is then aided by Naveen's valet, Lawrence by turning him into a Naveen look-a-like in order to trick the people of Maldonia. Doctor Facilier plans to take over New Orleans and the shadow demons will take the bodies of the citizens.

Powers
Apparently he has the ability to control shadows which can interact with people and objects in the real world. He is also a master of the dark arts which allows him to cast curses or spells on both humans and objects, such as turning Prince Naveen into a frog and bringing his voodoo masks and dolls to life during his demonstrations. He can also alter his appearance giving him more of a skeletal look. He claims that this is all possible because of his "friends" on the other side.
