Professor Coldheart is an evil professor in the Care Bears TV series. As the antagonist, he cannot stand the happiness in the land of Care-a-lot. He wants to get rid of the Care Bears and freeze over Care-a-lot, but his plans are always stopped one way or another by the Care Bears or a child who is with the Care Bears. He has a incompetent, brainless lackey named Frostbite.
He first appeared in the TV special "The Land Without Feelings" where he made a boy who said he didn't care (as a result of being upset that he had to move) drink a potion to take away all of his feelings, and turn him into a green creature slave.
