I can't believe that I need to explain this point or argue about it...
- First of all, Momo was a pure example of someone having Kaido's fruit which is what was asked for... regardless, a child or not. it proves my point... also, it's too soon to say what feats Momo will pull and state it as a fact.
- Secondly, you want a grown up man... look no furthur than Foxy... who has one of the MOST HAX FRUITS... a fruit in the hand of a powerful haki user, might make him a Yonko level by default.
- Thirdly, we already have example of "DF superiority"... meaning, just like Magma > Flame.... We have also Baby 5 DF > Daz Bones DF... yet, put the two of them against each other.... Daz Bones vs Baby 5... and I will put all my money on Daz Bones winning..
In fact, Strip away from Aokiji his Ice DF... and give him Monet's DF, and he would STILL change half the island atmosphere into snow and be an admiral level...
Again, I'm not sure why people think this topic needs to be argued LOL
