Name: Abura Abura no Mii.
Translation: Oil Oil Fruit.
Fruit Appearance: This fruit takes the form of a pitch, midnight black looking tomato.
Type: Logia.
Effects: This fruit allows the user to create, control and manipulate the petroleum substance known as fossil fuels aka Oil, this turns the user into an Oil Person.
The oil is a crude fossil fuel that grants the user the ability to control, create and manipulate all forms of oil, being the logia type means they possess the intangible aspect which turns parts of their body into crude oil to bypass physical damage.
The user can launch large spouts of oil much like a water cannon with force to knock people off of their feet, the user can start launching large balls of pure oil which is strong enough to splatter and crack wood.
And the user can launch miniature sized oil pellets like bullets strong enough to Pierce wood, the user can launch these oil bullets as fast as rapid fire machine burns to even large bursts like shotguns.
And more of the author's personal take but if one is smart/dumb enough, they can light their own arm on fire and start shooting fire coated oil to deal incredible fire damage while hurting the user.
Now lastly, this fruit also grants the greatest benefit most Devil fruits don't possess which is the ability to remain in water without sinking, since oil and water cannot mix, the user will remain floating on the top in a form of Pseudo Swimming.
Weaknesses: the oil produced by the user is still petroleum and is highly flammable so any sources of fire can ignite the oil.
