"Nito" comes from nitoro (ニトロ,nitoro?), the Japanese way of saying "nitro".
Strengths and Weaknesses
The fruit allows the user to sweat a nitroglycerin-like compound, which detonates on impact. This allows him to create explosions merely by clapping his hands.[1]
Aside from the standard Devil Fruit weaknesses, there seem to be no known weaknesses to this power.
Usage
Bürst can use his powers to create nitro bombs that explode on impact when launched at his enemies. Bürst can also take the appearance of a massive nitro dragon and fight in said state.[1]
