*spoilers*i think that dragons Devil fruit would 'blow away' Shanks before he could make use of his Haki

yes...agree as Dragon being level par as Gol d Roger....

@w99w99w. Heh, nice pun! XD

Anyway, Blackbeard should have featured on here, too. Possessing the Gura Gura No Mi and Yami Yami No Mi makes him a very tough opponent. Shanks is also very powerful, so I can imagine that he would give Dragon a good fight. Kaidou must be tough, too - so, therefore, I can't choose. I do agree that Dragon is very powerful, but so is Shanks and Kaidou.

yes Blackbeard must be one of the strongest but in fighting skills i think he still not reach other yonko level but maybe almost...

@jyndsix. I don't know about that... As far as I'm concerned, the three strongest would be Dragon, Shanks and Blackbeard. Kaido would be below them, I think.

while we don't know anything about Dragon i still go with Shanks if Franky makes him an artifical arm Shanks may pull out a fight with Dragon
