Tori Tori no Mi, Model: Vermilion Bird

The Tori Tori no Mi, Model: Vermilion Bird (トリトリの実 モデル：朱色鳥) is a Mythical Zone-type Devil Fruit that allows its user to transform into a Vermilion Bird hybrid and a full Vermilion Bird at will. It is "one of the only five types of 'flying powers' ever discovered.". "Tori" is Japanese for "bird". It was eaten by Kenjiro Wolfe.

Strengths and Weaknesses
This fruit enables a person to become a large Vermilion Bird and a Vermilion Bird-human hybrid at will, granting him enhanced senses of a Vermilion Bird, along with the advantage of having one of the only few Devil Fruits that allow flying. In his full Vermilion Bird form, he can carry other people on his back while flying.

This fruit doesn't seem to have any specific weaknesses, aside from the standard Devil Fruit weaknesses.
