Bunnymund

He is a Pooka; a fictional rabbit species that stands between six to seven feet tall, with grayish-blue fur, flower-like imprints on both his forehead and shoulders, and bright emerald-green eyes. He wears leather bracers set with orange stones, a single-strap holster with which he carries his boomerangs, and leather wrappings on his feet. In his disbelieved state, he assumes the form of a regular rabbit, but still retains the ability to talk.

Bunnymund is a cool, calm Australian as dry as the Outback. A natural ranger, he is in the dirt, rough and tumble protector of nature. He follows nature's rhythms and when it's time to spring into action he waits for the perfect moment to act. When he finally does, it's all over in a heart beat with the help of his exploding eggs and enchanted boomerangs. Bunny is completely unflappable. The only things that does get under his skin are North's constant ribbing about how Christmas is more important than Easter and his grudge on Jack Frost for causing a blizzard on Easter in '68. (And how Jack use to call him a Kangaroo.) Bunnymund takes great pride in Easter, and its corresponding season, Spring, stating Spring and Easter represent new beginnings, new life, and the Hope that comes of it. Aside from his tough side, Bunnymund is afraid of Greyhounds. Bunnymund greatly dislikes Jack Frost due to an incident known as the Blizzard of '68. Beyond it occurring on Easter Sunday, this blizzard and why it caused Bunnymund to hate Jack is unknown, but at the time of the movie, many years later, Bunnymund still held a grudge over it. As a result, Bunnymund was the most vocally against Jack joining the Guardians, even saying that he preferred the Groundhog (who Bunnymund had been hoping wouldn't be the new Guardian moments before) over Jack. He spent a great deal of time arguing with and competing with Jack, but as he got to know him better, seemed to grow to like and trust the young winter spirit. Notably, after Jack helps him with painting his eggs for Easter and have fun with Sophie Bennett, the two are able to share a friendly moment where they joke about one of their previous arguments. However, when Jack appears to have betrayed them to Pitch, all of Bunnymund's trust in him is shattered and he nearly hits the boy, but restrains himself at the last moment. His actions result in Jack getting thrown out of the Guardians and he is surprised when Jack returns to help in the end

Rabbit Prowess

Bunnymund has the physical prowess of a rabbit at its peak, enabling him incredible speed and jumping abilities.

Bunnymund has the power to control flora growth, sometimes making a flower grow whenever his tunnels close up. In the Warren, he has various flowers and plants with magical abilities that help him paint and decorate his easter eggs.

Bunnymund can open holes to underground tunnels by tapping his foot on the ground. This allows him to travel anywhere in the world in a matter of seconds. He taps his foot twice to travel, and appears to tap thrice to summon something from the tunnels, as he did when he summoned some of his sentinel eggs to fight Pitch and his Nightmares.

Bunnymund claims to be a master of Tai Chi with nerves of steel.

Bunnymund clearly has access to magic, given his enchanted boomerangs and explosive easter eggs.

Bunnymund's weapons of choice are his enchanted boomerangs, and wields them with uncanny skill and swiftness. He can easily take down several Nightmares with them single-handedly, up-close or from a distance, making him a very versatile combatant.

Bunnymund wields exploding Easter eggs to utilize as alternative projectiles.

As the Guardian of Hope, Bunnymund can sense and manipulate hope including the virtue of people, animals and other creatures. This is by either increasing, decreasing, causing or otherwise channeling hope, even manifesting the emotional energy to physical level.

Bunnymund's elaborately decorated Magic Eggs were designed to be little symbols of hope.

Bunnymund is the Guardian of life and hope. He can bring his Sentinel Eggs to help him with his Easter tasks.

Bunnymund, or Pooka, has the ability to shape-shift. By eating chocolate, Bunny can increase in power, size, grow extra arms or acquire the ability to fly. Bunny's shape-shifting powers are so advanced that he was able to change the Earth's shape from an oval to a sphere.

The movie, Rise of the Guardians, also reveals that Bunny has a decrease in power and size by the lack of belief which reduces him into a small and adorable bunny.
