Taku-Taku Fruit

The Burn-Burn Fruit (バーンバーン) is a Logia-type Devil Fruit that allows the user to create, control, and transform into fire at will. "Taku Taku" comes from the Japanese word "Yaku", which means to burn or the sound of burning.

The fruit had been eaten by "Black Fist" Dark Ranoki, First Mate of the rookie Pirate Captain,  Nitro V. Kaian's crew.

Appearance
The Taku Taku no Mi has yet to make an appearance throughout Hedgehog Piece: Grand Voyage, in it's fruit form.

Strengths
The fruit's main power is the ability to control fire and manipulate it anyway the user wants. Being a Logia type, he is also able to turn his body into fire, allowing him to avoid most physical attacks, although it is unsure if Dark has such mastery over his fruit that he is able to mimicry into fire. By mixing his fire in with other fire sources, he can control fire that did not come from him.

Weaknesses
Aside from the normal Devil Fruit weaknesses, if there is any other Devil Fruit that has the ability to produce a higher heat level, such as lightning or lava, it could be used as an advantage over this Devil Fruit's own heat by overwhelming it.

Trivia

 * The fire produced from the Taku Taku no Mi is an odd dark-greenish color, unexplained within the story on how that actually occurs.
 * This Devil Fruit is shared, in ability, with the canon Mera Mera no Mi.
