When Blackbeard touches a devil fruit user, it is as if they don't have
powers. Unlike the sea, when he drains your power, even physical property
changes to your body are cancelled out.

The [Wikia on Yami Yami no Mi](http://onepiece.wikia.com/wiki/Yami_Yami_no_Mi)
talks about this:

> This was shown when Luffy's stretching powers were canceled on touch, unlike
> the effect of a body of water or seastone, both of which just inhibit a
> person from controlling their powers. It was shown earlier when Luffy was
> stuck underwater that his neck could still be stretched above the water's
> surface, and that Busoushoku Haki would simply nullify the defensive aspects
> of a Devil Fruit such as intangibility and the malleability of rubber.

The episode they are talking about is episode 447. In this episode, Blackbeard
uses vortex to pull in Luffy and smashes Luffy into the ground. Crocodile
notes that there was blood. This is strange since Luffy, being rubber, should
be immune to the physical damage caused by being slammed into the ground.

Another use of the Yami Yami no Mi allowed Blackbeard to permanently remove a
devil fruit user's power and give it to himself. When Whitebeard died his
power was still active in Blackbeard, thus causing the fruit to not regrow.
This is proof of the permanent transference of power.

In either of these cases, either the case where the devil fruit user has their
power drained temporarily by touch, or permanently like in the case of
whitebeard, would the drained user regain their ability to swim?

question
one-piece
If Blackbeard removes your power do you regain the ability to swim?


If the devil fruit was not reborn then Yami Yami no Mi does not just take
powers, it takes the whole thing, like the person has actually ate another
fruit. Hence, I surmise that yes, a person would be able to swim again.

I don't quite understand the point of such questions. Its clearly never been
made clear the extent of BB's powers. (Logia intangibility, Removing other
DF's powers etc. etc.) Unless Oda decided to make this a plot point somewhere
down the line, I wouldn't really care how the DF mechanics work for the Yami
Yami no Mi. But fans are really passionate about it So here's my answer. There
is no real point in it.

It is shown quite clearly that BB needs to be touching the user to negate the
DF powers (Whitebeard and Ace fights). So in order for a DF user to swim,

  1. BB sits in a boat, holds one arm or touches the body of DF user. The boat has to follow the same exact path and speed of the swimmer and the instant BB loses the touch DF user drowns and BB can't save him. Unless the boat can just have 1 pirate on it, I'd rather just row.
  2. BB himself can't swim being a DF user. He will lose strength and from what I know the Yami Yami no Mi power is not auto triggered.

Thus only plausible scenario is

  3. That BB can maintain his DF fruit power even when he is submerged in water, and then a DF fruit user can carry him across water.

I think 3 is improbable since Crocodile did say that he has trained himself to
turn into sand. Similarly BB needs to concentrate to hold his DF power and
wouldn't be able to do so if submerged. Thus this power is imho
inconsequential.

I don't think that Blackbeard can remove the power of Devil Fruit permanently
and the victim can't regain the ability to swim.

Just like stated [here](http://onepiece.wikia.com/wiki/Yami_Yami_no_Mi)

And also this
[part](http://onepiece.wikia.com/wiki/Yami_Yami_no_Mi#Weaknesses) stated that
Blackbeard can nullify the power of other Devil Fruit users if he touch them.

> In addition, while the ability to nullify Devil Fruit abilities is very

So, the victims can't regain their ability to swim if Blackbeard doesn't touch
them to nullify their Devil Fruit power.

They can probably, swimming by carrying Blackbeard on their back.

Doubtful. I think to completely rip off powers from another Devil Fruit user
like Whitebeard, he probably needs to be dead or will die in the process.
Think about it if that weren't the case, then Blackbeard would have extracted
the Mera Mera no Mi's power from Ace when he initially captured him. The thing
would've killed Ace and that wouldn't allow for a situation where Whitebeard
went to war with the World Government.
