Rookidee

Rookidee is a small bird-like Pokémon that is primarily dark blue, including its wings, tail, back and part of its head. The lower part of its body and chest is yellow and has a black part that begins from under its wings to its face, from which feathers protrude over its head, giving it a mask-like appearance. It has red eyes and small gray feet and legs.

Rookidee are feisty and territorial Pokémon and will bravely fight against anybody, no matter how big and strong that opponent is. They somehow can be able to store some of their own energy after every battle even if they lose, so they can grow a bit stronger. Using their legs, they are able to jump nimbly from place to place to confuse Pokémon bigger than themselves.
