The Jetto Jetto no Mi (translated from Jet Jet Fruit) is a Paramecia type devil fruit that gives the user the ability to make themselves or any part of their body speed up making them a Speed Human. "Jetto" means "jet". This fruit was eaten by Spade, the first mate of the Slayer Pirates.
The fruit resembles a red mango with swirls all over it.
Strengths and Weaknesses Edit
The major strength of this fruit is that it give the user the ability to become faster than sound and this can be used to enhance many fighting techniques. (E.g. The user will be able to cause sonic booms with each punch you make.) The fruit can also speed up the user's body, giving them a form similar to Monkey D. Luffy's Gear Second.
One of the main weaknesses of this fruit is that it puts great strain on the user's body if used for a long period of time. Other than that, it has the standard devil fruit weaknesses.
When this fruit is awakened it gives the user the ability to run faster than light, but will shorten the users lifespan by the amount of time they use that ability.
Spade uses his fruit to make his punches faster and more ferocious than they usually are. After being around Luffy for awhile, though, he was able to copy and enhance some of Luffy's Gear Second attacks. Spade also makes his blood move around his body faster so that he can have better endurance.
