Kami Kami no Mi, Model: Agni

The Agu Agu no Mi is a paramecia devil's fruit that allows the user to synthesize any type of fire in their palms and control that fire. This is not to be confused with the Mera Mera no Mi, which allows the user to create, control, and turn into fire. After the fire created has been controlled for around a minute total, the user will lose control of the fire. Once the user releases their control over the fire, they will no longer be able to control it. The user can also be harmed by the fire they create. There is no current user, and this devil's fruit is currently located in the Devil's Fruit Vault.

Strengths
The fire generated by this devil fruit can range from an average wood fire to fire generated by magnesium, which can permanently blind those who look at it for too long. It can also generate cold flames that are similar to those generated by the Aoi Aoi no Mi, except for the fact that they are actually fire rather than a "cold fire effect". Using both hot and cold fire, the use of this devil fruit can regulate his body temperature, meaning that he's immune to any type of temperature attack.

Weaknesses
Once the fire generated is out of the user's control, it can harm the user. The absolutely fatal fire that can tank buildings and enemies alike can also be the reason of the user's defeat. The more harmful the fire, the more stamina it takes to synthesize it. Other than this, the user of this devil fruit suffers from normal devil fruit weaknesses.

Attacks
Currently, there are no attacks as this devil fruit has no user, but below is a list of fires that the next user will most likely use.

Wood Fire - An average fire that's blue at the bottom and orange tipped due to sodium impurities. There are two types of this. Magnesium Fire - Magnesium fire is much brighter than wood fire, and it is much brighter too. It is completely orange in color. The fire is incredibly hard to put out, and only dry, sand-like substances can put out the fire. If anyone stares into the fire for too long, they will become blind.
 * Complete - A complete fire is the easiest to generate. It is reasonably hot, and is also the fire that Portgas D. Ace's entire devil fruit is based off of. The blue part of the fire is easier to see than when compared to an incomplete fire.
 * Incomplete - An incomplete fire is not as hot as a complete fire, but it produces toxic gases that will render anybody, including the user, unconscious.

Fluorine Fire - Fluorine fire is the brightest of all the mentioned fires. It is yellow-orange with a green tinge. The fire will burn through nearly anything except for incredibly resistant metals like platinum, tungsten, molybdenum, and aluminum.
