Jitsu Jitsu no Mi

Name: Jitsu Jitsu no Mi (From Genjitsu = Reality so Reality Reality Fruit)
Type: Paramecia
Abilities: Jitsu Jitsu no Mi is a paramecia type devil fruit that grants the user the ability to manipulate reality itself. The user is able to turn things he has touched to something unreal and things that do not exist such as illusions into something real for one (1) post.
When the user turns a thing to something unreal, that thing still keeps its appearance as if it is real, but is nothing more than a hologram, something that behaves as if it does not exist. Being a hologram, the object cannot be touched and it cannot be moved from the position it turned into something unreal, unless it is moved by a person who can manipulate reality, in other words the user. This ability has a cooldown of one post (1) post, before being reused on the same thing again. The ability is triggered like the ability of the Fuwa Fuwa no Mi. Once the user has touched a thing, he can manipulate its reality to turn it to unreal whenever he wishes, unless that thing's reality has been manipulated recently (while the ability is under cooldown).
On the other side, the opposite happens when the user manipulates unreal things to make them real. The things turn into something real and their pressence can be seen and felt at the area as something real. As those things are a reality that is created by the user, they can be controled by the user. The user does not have to touch these unreal things (illusions) to make them real, although the user himself is unable to create an illusion by himself, making this ability actually useless unless there are illusionists around the area. This ability lasts only for around 5 posts. Only 1 illusion can turn into reality at once and the cooldown to make an illusion reality is to wait for as many posts as the previous thing that turned into reality lasted. So, if an illusion that turned to reality lasted for 5 posts, the user will have to wait for 5 more posts before being able to reuse that ability. The maximum size of an illusion that turns into reality is that of a normal giant. The bigger it is, the harder it is to make it real and to control so that the user cannot always turn giant sized illusions to reality and it is preferable to turn small sized illusions to reality.
The disadvantage of the fruit is that it can only be used only on non-living things. This makes it quite similar to Fuwa Fuwa no Mi, although Fuwa Fuwa no Mi affects the user, too, while this fruit's ability cannot be used on any people, including the user.

I only have two problem with it. There's a lack of description on what an Illusion actually is. If it isn't caused by a devil fruit, then illusions are pretty much existing things that only appear as something else, so in a sense, they're already real. What you're talking about here are "true" illusions, the kind that are produced from devil fruits, or possibly holograms even though those don't exist in One Piece. In other words, I didn't understand what types of illusions can the second power affect.

Also, I think the second power should be a little more limited, since if you'll get a decent illusionist with you, you'll be potentially capable of summoning entire armies, or gigantic weapons and monsters under your control without any drawbacks, which sounds a bit overpowered to me. Also, since the illusion becomes real once you affect it, you can potentially turn it back into an illusion at any time, meaning that you're pretty much neutralizing the drawback of the first power regarding that specific illusion, AKA an abusable loophole. You'll gain a monster under your control, that you can zap in and out of reality with will power.

true, those are some things that I actually did not think of. Well, I will make the second ability able to last only for around 5 posts (just like the first ability). Only 1 illusion can turn into reality at once and the cooldown to make an illusion reality is to wait for as many posts as the previous thing that turned into reality lasted. So, if an illusion that turned to reality lasted for 5 posts, the user will have to wait for 5 more posts before being able to reuse that ability. How does that sound?

And yes, with illusions I probably mean things that are created by fruit users - unreal holograms.

I guess that'll work, but you might want to include some size limits on what illusions you can turn into reality. Since an illusionist has next to no limitations on the illusions he can create, you could very easily control an island-sized monster.

well, what about the size of a normal giant for the biggest illusion. I can also make it so that the bigger it is, the harder it is to make it real and to control so that the user cannot always turn giant sized illusions to reality

Works for me, add it and it's approved
