One Piece Episode 449

[DarthEnderX]

Having ambition isn't the same as being able to concentrate ambition into an attack that negates devils fruit abilities.

Why do you think Haki negates Devil's Fruit abilities? They haven't said anything like that.

The only thing that "negates" fruit abilities is Sea Stone, the Darkness Fruit, and weaknesses of specific fruits to specific materials.

Raleigh's Haki didn't suddenly "negate" any of Kizaru's powers. Kizaru's light sword didn't suddenly vanish when Raleigh made contact with him.

When a Haki attack hits a Logia user, it works, because the fruit makes their body invincible, not their spirit.

In the same vein, if Flamingo used his powers on a Logia user, they would work, because the fruit makes their body invincible, not their mind.
