Raymond Roger Rabbit, better known as the Easter Bunny, is one of the main characters in Rise of the Guardians. He speaks with an Australian accent and is known as the Guardian of Hope. The Easter Bunny is a "Pooka", a philosophical warrior rabbit, and lived with the other Pookas in his village before his village was wiped out, leaving him as the only survivor. He currently lives in his burrow, an oasis deep beneath the surface of Australia, said to be the birthplace of spring.

It is a rabbit, of course with a larger size, it carries two boomerangs and a belt across its chest, which holds in the front, four explosive eggs.

His height is one meter eighty-five (1.85).

When the children stopped believing in him, he turned into his past form, a furry bunny with the ability to speak.
Since it is an anthropomorphic animal, it has the ability to smell or hear more acutely than humans (an example is when it is in its burrow and hears something that is soon to be Sophie Bennet)
Jack and Rabbit are rivals for pride, both are quite stubborn and resemble each other in some ways, they could be good friends.
