I mentioned in the character creation rules and expectations, but i'll go in a bit more depth. Generally speaking i'd like for you to use canon compliant fruits even those presented in filler material is allowed. Not to say that I won't allow you to make your own new Devil Fruits, but I'm very interested in seeing people use druits already in the story, especially the powerful ones and see how rookies deal with them, or just seeing how a different person will use that fruit. For example I feel like the Slippery Fruit by Alvida, the Bubble Fruit by Kalifa, the Weight Fruit by Miss Valentine, Rust Fruit by Shu, and the Berry Fruit by Very Good can be explored more and are interesting fruit that can be given justice.

In terms of what fruits are allowed just due to the nature of where the story is I won't allow any Logia fruits. Now if you do want to make a character who has this fruit right now I won't stop you, but know that they cannot have it at the moment which means you can plan to make them eat it at a later time, when I feel like it's appropriate in the story. This means that you're character has to be able to fight somehow. Outside of that it's free game for all Devil Fruits and types, i'm even allowing Ancient and Mythical Zoans, but must be discussed with me just in case they're too OP.

*NOTICE for ZOAN DEVIL FRUIT USERS*
There are Artificial Zoan fruits in the story. They're basically zoan devil fruits that are give the same effect, but can be weaker, weirder, or only change to just one part of your body. If you want your character to have this it's fine, feel free to talk to me more. 
The other thing that's common for the One Piece world are "Devil Pills", which are basically Chopper's rumble pills, much sought after drugs in the Grand Line.

Just due to the game breaking nature of it's powers that I'm not allowing 100% is the Darkness Fruit by Blackbeard. 

The other thing being that i'm sort of limiting Devil Fruits to humans only just because other races have racial and tribe powers/skills inherent to their species/culture. This can be discussed tho.

EDIT:

Lol i posted this after Prewiga beat me to it lol. Regardless here are still some information

To everyone that is curious here is a bit on the Captain, this is especially important to those that want to be a part of the crew already

They are a fairly serious person, charismatic, and mellow. When they found you and requested you to join their crew they asked for you because they saw as being skilled and experienced, and someone he needed on his crew. They offered you money and a chance to help you fulfill a dream or a desire of your choosing so long as it wasn't anything vile. They also made it known that they have no desire to become a pirate king, but rather that it may just end up happening that way since their goal aligns with the requirements to be pirate king. They made it known that he there will be people that will die, but he doesn't entertain needless killing or violence for the fun of it, but they should be comfortable with the fact that he is looking for certain people that he will fight and may end up killing, but as crew they don't have to kill anyone for his sake (unless they choose to do in case soemthing happens)

Note that I'm keeping their gender vague just for character balance issues. They will be human, and they may or may not be a Devil Fruit user depending on what happens with the characters.
