The Ton Ton no Mi is a Paramecia-type Devil Fruit which allows the user to increase or decrease their weight, making them a Super Weight Human (超体重（スーパーウエイト）人間 Sūpā Ueito Ningen?). It was eaten by Machvise.
- "Ton" is the short version of metric ton.
Strengths and WeaknessesEdit
The fruit allows the user to increase or decrease their body weight by incredible amounts, leveled by metric tons. This allows them to land crushing attacks that can easily crack the ground and even a giant's bones.
The fruit is superior to the Kilo Kilo no Mi, since while both fruits revolve around manipulation of body weight, the user of the Ton Ton no Mi can become much heavier than the Kilo Kilo no Mi's maximum of 10,000 kilograms.
However, the fruit's power will prove ineffective should an opponent be capable of withstanding the selected weight, and can even use the force of the weight against the user, as shown when Hajrudin defeated Machvise. The user is also susceptible to the effects of added weight if they miss their target, as seen when Machvise suffered from his own attack when it missed Franky. Other than that, the user is also affected by the standard Devil Fruit weaknesses
Machvise uses the fruit in combat, and his main style of fighting involves getting above his targets high in the air, then swiftly increasing his weight to fall on his enemy with his stomach, in an attempt to crush them on the ground.
- 10 Ton Vise (10tヴァイス Jutton Vaisu?): Machvise floats above his opponent then crashes down with his limbs outspread. He is able to cover a large area with his huge body. It was first used in an attempt to crush Franky after Senor Pink protected him from the cyborg's rocket launcher, and named when he used it against Luffy, this time with Senor Pink holding their opponent's legs down with the help of his ability. Luffy managed to escape by stretching out of the way, and the impact of being hit with 10 metric tons did not appear to affect his rubber legs. The first time he managed to strike someone down with this technique was against Boo.
- Hakai no Senton Vise (破壊の千tヴァイス Hakai no Senton Vaisu?, literally meaning "1000 Ton Vise of Destruction"): 100 times heavier and more destructive version of 10 Ton Vise. While performing this move, he uses his unique shield to increase its power. Machvise attempted to use this move against Zoro but abandoned it midway in favor of using 10,000 Ton Vise against Hajrudin.
- Jigoku no Manton Vise (地獄の万・t・ヴァイス Jigoku no Manton Vaisu?, literally meaning "10,000 Ton Vise of Hell"): 1000 times heavier and more destructive version of 10 Ton Vise. While performing this move, he uses his unique shield to increase its power. It was first seen used against Hajrudin and was capable of shattering the bones in Hajrudin's forearm and leg and cause him to grit his teeth so much that a tooth broke, as well as crushing the ground beneath Hajrudin, but nonetheless was forced back by the giant's Gungnir, sending him flying.
