Cheshire Cat

The Cheshire Cat is Alice Liddell's primary ally and principal companion in Wonderland. He is a talking cat that constantly smiles, and can disappear at will. Although a friend to Alice, the Cheshire Cat commonly has a snarky attitude towards her and she always returns the same treatment.
Alice comments that she feels he might be her "alter ego", giving voice to the doubts and fears she is unable to express. Cynical, sarcastic, distant, philosophical, flip and earnest, he can render valuable service.
