first of all i do know that there is a thread about devil fruits in general but i dont find it suitable for this kind of discussion.
ok, so we all know that there are a lot of application for devil fruits, and a lot of people dont use them to their fullest potential. in this thread i hope people will try to come up with potential uses for each devil fruit and how to maximize the ability of the user to use his powers.
first of all a complete list of the DFs weve seen so far (taken from one piece wiki, note that i list only non fillers in here, movie DF's and fillers are not listed)

rules:
-dont contredict oda.
-you can use any number of DFs you want.
-do not spam/flame/harress other people for their ideas
-try not to come up with application we already saw.
-for now dont use any DF that is not on the list, we are not here to come up with new stuff.
-dont use a DF that is revealed in the spoilers or the last chapter (some people have yet to read them and we dont want to ruin for them)
if enough people will ask ill add a list of filler DFs.
ill go first:
doa doa no mi (door door devil fruit, used by blueno), an almost instant kill usage i came up with after seeing blueno vs luffy again is opening a door at the chest of the foe, revealing his heart, lungs etc. and just killing him on the spot, in order for that to succeed the user should go into the door dimantion and from there try to use doors on the hands and legs of the target in order to render him immobolized and finish him off. fatality!
another devil fruit i would like to try is sebi sebi no mi (rust devil fruit, used by a captain that came with buster call) sinse rust is just oxydizing, and in theory can work on everything, the user should aim for the neck to puncture the breathing tube resulting in suffocation, another usage is just rust everything on the foe's body in order to make him vulnruble (i mispelled that i know).
have fun!
