The Queen of Hearts

She's the arrogant and harsh queen of wonderland, who bears a resemblense to Candace. Unlike her who can forgive mistakes against her sometimes, the Queen orders execution with a so much as a mistake in her order of breakfast. She's extremely attached to the statue of her in her garden. Like Candace is annoyed by Phineas and Ferb, the Queen bears animosity against their lookalikes, the Mad Hatter and the March Hare. Candace befriends the Queen and she treats her to grade A hospitality in her castle. When the Mad Hatter and the March Hare tear down the Queen's statue, and leave Phineas and Ferb with the evidence, she orders them excecution. When Candace frees the boys, the Queen orders her guards to kill them all. When the boys notice the Hatter and the Hare in the Queen's garden, they try to keep the Queen distracted by destroying the Queen's newly rebuilt statue and leaving them red handed (but mostly for payback). The Queen turns her attention to the Hatter and the Hare, and orders their excecution while Phineas, Ferb and Candace get away.
