Victini

Victini is a small, rabbit-like Pokémon with large, pointed ears which form the letter V. It has large, blue eyes and a round, cream-colored head, which is comparatively large compared to its small, cream body, while the tops of its ears, crest, and extremities are all orange. Its bulbous arms and legs are rounded to make a sort of "cuff" before ending with small, three-fingered hands and two-toed feet. It has two pointed teeth that can be seen on its upper jaw. It also has two cream winglike tails, which allow it to fly. Though timid, it is a caring Pokémon; it will fight if its friends are in danger.

Victini is said to bring victory to the Pokémon Trainer that befriends it. It produces an infinite amount of energy within itself that it can share with others by touch. It can also become invisible. In White—Victini and Zekrom and Black—Victini and Reshiram (M14), Victini is shown sending visions to people and enjoying macarons. In Pokémon Adventures, it's stated that people who believed the legends of Victini's power waged war to get their hands on it.
