So, I've got a few ideas for Devil's Fruit powers. I'd like some opinions on which one I should use, as I'm having a hared time narrowing it down. xD

Ken Ken no Mi (The Fist-Fist Fruit) - Any surface that the character touches, a fist can emerge from that surface. At the will of the user, the fist comes out of the surface like an arm in a straight line, and the fist/arm disappears at the will of the user.

Kooto Kooto no Mi (The Coat-Coat Fruit) - The user touches a nonliving surface and is able to coat themselves and/or other objects or people that they simultaneously touch in a material identical to the nonliving surface. Obviously, would not work with seastone. For example, a wooden ship allows the user to coat himself in wood. But touching the bark of a tree would not work, as that wood is still technically alive. Works only with solid materials and nothing loose/shifty (like sand) or any liquids.

[indent]NOTE: It's merely a coating on top of the skin. It does not change his body into that substance, so it is different from Logia-types. But I can see the problem arising from its similarity, so this will probably be the first one I'll eliminate...but eh, we'll see.[/indent]

Chika Chika no Mi (The Vison-Vision Fruit) - The user has extremely sharp vision. They are able to see even the tiniest of details as long as they have line of sight. They can also see extremely far distances very clearly, like a telescope.

Kangu Kangu no Mi (The Kanga-Kanga Fruit) - A Zoan-type fruit that allows the user to transform into a kangaroo or a Kangaroo-human hybrid.

Kawau Kawau no Mi (The Otter-Otter Fruit) - A Zoan-type fruit that allows the user to transform into an otter or an Otter-human hybrid. Note: The otter cannot overcome standard Devil's Fruit weaknesses, and thus cannot swim.

Ope Ope no Mi (The Op-Op Fruit) - You all know what this one does. I figure, we've got the String Fruit user, so this could be fun to use beside that one as a novelty. Plus, it would give me an easier way to explain if I want to make another doctor character.

Nui Nui no Mi (The Stich-Stich Fruit) - You should also know what this one does. I figure that this will be a pretty underplayed power in the anime, so it could be fun to use to a greater extent.

So a better question: Anything I should eliminate right off the bat? Personally, I'm leaning more toward the latter five, but...I'm still not sure. xD
