Peter White is a character who has fallen deeply in love with Alice. He believes that she should return his feelings, but Alice refuses to acknowledge him. Despite this, Peter remains close to Alice and becomes very jealous when she interacts with others like Ace and Boris. In addition to having white rabbit ears, wearing a watch, and a suit coat, Peter has little in common with the White Rabbit upon which he is based. He is the first character to meet Alice and claims to be desperately in love with her. However, his sociopathic tendencies mean that he will not hesitate to kill anyone who gets between him and Alice.
Alice mentions hating Peter on several occasions, but he remains persistent in trying to win her over. One of his methods is to transform into a rabbit, which Alice seems to find endearing since she has a soft spot for animals. Peter works as the Prime Minister for the Queen of Hearts in Heart Castle and often rhymes when speaking, although this is not evident in the original version. It appears that Peter and Nightmare have some knowledge about why Alice was brought to their world and may be connected to her older sister in some way.
