Cheshire Cat

From The Unofficial DisneyWiki

The Cheshire Cat is a mysterious pink and purple cat with a devious, mischievous personality. He has a permanent smile on his face tand can disappear at will. He appears in the film Alice in Wonderland. Alice encounters him in the woods shortly before entering the Queen of Hearts' domain, which the cat warns her of. The Cheshire Cat also appears in the Wonderland world in Kingdom Hearts and Kingdom Hearts: Chain of Memories.

Despite being a generally neutral character, the Cheshire Cat is apparently considered a villain by the Walt Disney Company, as evidenced by his inclusion in Disney Villains merchandise.
