Mato Mato no Mi

The Mato Mato no Mi is a Paramecia-type Devil Fruit that makes the user capable of aiming at which ever "target" he decides upon from any location and at any time with anything at ease. "Mato" (的) means mark or target in Japanese. It was eaten by Vander Decken IX.

Strengths and Weaknesses
This fruit makes the user capable of aiming at which ever "target" he decides upon from any location and at any time with anything at ease. With the distance and acceleration of the projectile the user is sending it is a very dangerous ability for it can actually give a greater force in its attack as shown by Vander Decken IX when he sent an axe towards princess Shirahoshi, where its acceleration gives a greater force to the axe blow. That blow could actually be fatal.

While this ability is capable of sending objects to the target, it doesn't give the user the capability of controlling the direction or trajectory of the item, it will just follow a path to the target, moving past every thing along the way. That would mean that if the item is blocked by something or somebody, the effect of the fruit will be nullified. It will not act completely like a homing device. This is shown when the axe Vander Decken IX threw cut his ship's mast and was blocked by Luffy, but it doesn't follow its target, in this case Princess Shirahoshi. Besides that, he also cannot touch people with his hands for some reason anymore (possibly touching someone else other than the target, will most likely make said someone that target instead). Other than that, the use is still affected by standard Devil Fruit weaknesses as shown when Vander Decken has to leave his ship in a Flutterkick Coating, despite being a fishman.

Trivia

 * This the first Devil Fruit shown to be eaten by a fishman.
 * Like Bartholomew Kuma, Decken apparently has to wear gloves to control some the effects of his Devil Fruit.
