Already created one and posted it, the

Force Force Fruit. it has way too many moves

Also had an idea for a paramecia type devil fruit that gives abilites similar to boogie woogie from jjk if yall have watched that

Huh isn’t that just the one guys quirk from mha?

I made a plastic fruit as my first one and it originally had a whole user and stuff but got taken down a long time ago

I could copy and paste it from my notes though

Yeah, it was based off of Twice from MHA, but I tried to keep it as different as I could, but I kinda failed.

I’ve done most of my best ideas but I’d say my number 1 favourite was the Seiun Seiun no mi (nebula fruit) which was a sick logia.

Tetsu-Tetsu no mi (Iron Iron fruit) would be very similar to Kid's fruit, but Instead of just magnetizing, there would be many other things that you can do. You'd be able to control anything made from metal or partially, like the Pacifistas, Franky (lol), the Iron giant, and even Marine battleships. That's not it though, you could turn yourself or other people into metal. You'd have to be able to touch them though, and these abilities would be useless on a logia devil fruit user unless, obviously, you could use armament haki. You could turn your arm into a blade like Daz Bonez or yourself into an iron statue so it's hard to hit you without breaking your hands. Since metal conducts electricity, you would be able to electrocute your opponents like Enel.

Also really similar to the Supa Supa no Mi (Dice-Dice Fruit) because that turns your body into steel

So really the Tetsu-Tetsu no mi would be a combo of like 3 different devil fruits
