Natural Opponents

[Polemidis]

maybe you can also add Jewelry Bonny vs Luffy at a food contest :P

 

[Lobotomy Jane]

I dont know if someone has posted it already, but the most clear natural oponents are Sanji vs. Boa, since he's totally unefective against women, even more if they are beautiful.
But hey, this guy will perfectly be defeated by any woman :/ so i think it's better said Sanji vs. Female

And anyone can think about a serious oponent to Doflamingo? I think it's almost imposible to defeat a person who can control your movements. Does the Haki can act against his devil fruit power?

Because of his natural chivalrous nature, it is true that Sanji could possibly be defeated by any female as he would not attack them.

So far, Doflamingo has only been shown to be able to easily manipulate the actions of weaker characters, I expect he would find it difficult to control stronger people. Though it has been hinted that Haki can counter the effects of Devil Fruits, it has not been confirmed that Doflamingo is using Devil Fruit powers.

Smoker Wind

Smoker is afraid to use his powers when the weather is windy but that's not to say, wind is a crippling weakness. Smoker is able to increase the density of his smoke (allowing him to grab/attack objects), which may prevent it from getting blown away by wind.

Paulie vs. Buggy

Paulie can tie every floating part of Buggy when he's atacking

kuma can repell his entire poison on the other hand take him down with some laser
