Glutton resulted in the user sprouting three extra mouths on his body, with the ability to sprout additional mouths from any other place if he so desires. Using the three mouths he can eat virtually anything and recycle it to create explosive clay and then mould it into various shapes and forms that he can control. He can even change the properties of the clay he creates, making a less potent non-explosive kind of clay if he so desires. The three permanent mouths appeared on the palms of both his hands as well as a larger one on his chest. These three mouths are the only ones that can be used to mould the clay, the other temporary ones can only consume things.
The greatest use of this fruit is born from the explosive nature of the clay, which allows him to create bombs of various shapes and sizes, as well as of varying strengths. He can even mould animated dolls made out of the clay that resemble animals. So he can mould the clay into the shapes of birds, animals and insects and use them for scouting purposes, helping him greatly in tracking and following a target, or even for information gathering as any information gathered by the animals is shared back with him. Thus he can see what they see, hear what they hear and even smell and sense environmental conditions through them. These dolls retain the abilities of the creatures they where modeled after, i.e. those resembling birds can still fly, spiders can spin webs made of the clay they are born from and so on. He can also create "living bombs", creatures made out of the explosive clay and by imbuing his magical energy into them, can be remotely controlled by him and made to travel over great distances and explode at just the opportune moment. This makes the user particularly effective at long range combat, as he can use these living bombs to create explosions without him having to get in close with his target.
But while these various animals alone make Glutton a very versatile and dangerous magic, its true powers lie not with what it can crate from recycling what it has consumed, but what the mouths can directly do. The explosive nature of the clay is born from the explosive nature of his saliva, which can in turn be imparted to anything the saliva comes in contact with.
