Aba Aba no Mi

The Abata Abata no Mi is a Paramecia-type devil fruit that grants the user the ability to summon a shape-shifting physical incarnation. The summoned avatar takes the form of the user's required task, but is limited to it's user's own psyche, will, and abilities.

Strengths
The fruit allows the user to summon from his body a physical incarnation that has its own personality and will, although it is shared by its user. The user also has total command of the summoned avatar, as long as his will and strength is enough. The avatar is quite powerful, usually near the strength of its master when the ability is first activated. It may grow in strength by two ways, by training the ability itself or by the user increasing his own strength. Basically it's not only an extension of the user's will, but also a separate entity in of it self.

The summoned avatar shares its mind with his master, so while the avatar is inside the user's body, they communicate telepathically, as it exists as another entity inhabiting the user's mind and body. It may be summoned in various ways as well. It can surround the user's body as a sort of shield, or it may project itself outside it's user as a separate entity, although still connected to its master. When projected outside, its abilities may become weakened after a certain distance away. While he is released, even if the avatar is in a far away location, it is possible for it to hear the words of his master.

The summoned entity may have various forms, all dependant on the will of the user. But in it's most basic forms, it has a defense form and an asault one, and each form may have its own stages and variations. In its most basic forms, the avatar may be manifested and it can stay invisible as long as its kept a few feet from the user's body. Keeping himself invisible also drains stamina. Changing forms or advancing them drains the user. If the avatar is damaged, it can repair itself by being summoned again, or advancing to a higher form, although, similar to humans, it needs actual rest to fully recover itself, as it may grow weaker the more its injured.

The avatar is a physical mainfestation, as such, it protects its user against physical attacks, but it may still be affected by other sorts of attacks and devil fruits. If its caught under a Devil Fruit ability, the avatar can be resummoned for its negative effects to be removed, however, it will be weakened still.

Weaknesses
The user has to actively summon the avatar. Another downside is their shared mind, as the avatar may overwhelm its user by being present as an entity inside his mind. The avatar also drains the user's stamina every time its summoned or changes form.
