The Ton Ton no Mi is a Paramecia-type Devil Fruit which allows the user to increase their weight, making them a Super Weight Human (超体重（スーパーウエイト）人間, Sūpā Weito Ningen?). It was eaten by the former Donquixote Family combatant Machvise. The fruit's power was shown during the conflict of Dressrosa, but was not named until it was revealed in SBS Volume 79.
