Its a risky assumption :
I think Shanks has a devil fruit links to teleportation or speed.
Tabi Tabi no Mi
Sugi Sugi no Mi
Or Shanks crew don't own devil fruit, Shanks is a master at haki, king's haki therefore he is the fastest dude.
This is only possible if Shanks ate a df after getting his arm bitten off while saving Luffy from the seaking. He likely has no df but has awesome haki attributes.
Here's a crazy Devil Fruit power I've been thinking of for some time. Suppose there's a DF that allows one to contain a ship or sea monster within a bottle or some other container. The being in the bottle is able to survive inside and after being contained for three hours, they fall under the users control and can be released at any time to do the users bidding.
Its two main weaknesses are that the user can't contain one whose strength is greater than the users and they must recontain their released slaves within three hours or the spell will be broken.
What do you guys think?
This seems like a hax version of Capone's fruit with some Bartolomeo fruit mixed in.
Well for my first post here, I suggest another tangible intangible fruit...cement cement fruit. It would be the senpai version to crocodile's fruit but this one is tougher. Whereas Crocodile is sand, this one is concrete. If water is added he becomes liquidy yet stable and abrasive. If the user is dry enough, they can "vaporize" away like dust. When the user is in a normal state, he is pure solid concrete like Joz is solid diamond. If the user is awakened, the power would be the ability to turn stuff in the near viscinity into concrete and depending on the weather the user can change the consistency of said concrete.
Tangible: solid state
Intangible: dust state
Semi tangible: wet concrete state
Yeah, so long story short, it is quite the fruit.
2nd fruit suggestion would be metallic metallic fruit. This one lets you generate metal stuff. It also makes it so fire attacks will be super effective since like in Pokemon, fire melts metal lol...the good part about this is depending on how and the speed of metal being created, a magnetic field can be created from metals constantly crashing into each other. In fact, I took this idea from a story I wrote in high school where a dude can generate metals from the ground with such force and speed he can create a magnetic field to suck people in due to all the metal armor they be wearing.
