Mathison Fischer/Powers and Abilities

Devil Fruit
Fischer at the age of seventeen, consumed the Hobi Hobi no Mi, a -class Devil Fruit, turning him into a Hobby Human. Due to the secondary effect of the Devil Fruit, he has ceased aging and thus will remain physically young for as long as he should live. Because of this, he has obtained a form of semi-immortality in the shape of eternal youth, allowing him to live on for an indefinite amount of time without falling to the effects of old age. This does not, however, make him immune to diseases, poisons, or anything else that could kill a human.

Those in the past who have seen the effects of this fruit have made the misconception of believing that the user is only capable of turning living beings into various forms of "toys", alongside controlling them, though this is not truly the case. This fruit allows the user to manifest their "hobbies" in various ways, whether it be creating and controlling objects based on the hobby, or even turning others into those objects on their own whim. Like many things, one's hobbies are determined by the user's personality, their age, their interests, and in some cases even their level of intelligence. Fischer is unique among the past holders of the Hobi Hobi no Mi, because in his hands the fruit encompasses two of his hobbies: "tinkering" and "games". Because of his first hobby, Fischer is capable of transforming people into various mechanical creations, erasing memory of them once they are transformed, alongside manifesting these creations out of thin air and modifying them, whether a human turned machine or one made from nothing, with a simple touch. His second hobby allows him to take command of an area around himself and become the Gamemaster of said area. As the Gamemaster, he is able to set rules for the area, roles for people within, and he can even turn people into "game pieces" that he can control with ease.
