I know I'll take a lot of shit for saying this but I think your a level headed dude I think Dragon is stronger I think he will be what Madara is to the 5 hokages. Think about it he has to be he wants to change the world and you have to have immense willpower/haki to do that not to mention his physical strength and hand to hand combat will be at prime garp level on top of having an OP DF and the best haki
Not neccesarily.
Dragon does not need to be the strongest in the world to topple the WG(his goal)
However he does NEED to be above admiral level(or the admirals could just kill him in battle, and then massacre his comrades)
Buggy is a shichibukai. But he has not shown really powerful fighting techniques. He became a shichibukai through ammassing a lot of strong followers. He used quantity of people vs quality.
The same could be said for dragon. His main power may be his allies, not himself. Still, since he is the son of Garp(who was rogers level), and the father of luffy(who will become PK level), he is certainly very OP.
His bounty is based on more of the fact that he is toppleing kingdoms, and is very dangerous to the survival of the world government.
I think dragon is yonkou level or above. I do not think he is neccesarily the strongest in OP. If I were to guess right now, I would say he might be able to 1v2 yonkous.(just yonkous, not their crew)
I very open to the possibility that I may be wrong. This is just my opinion.
To the topic. Sabo was boss. I cant believe some people thought he would be weaker than luffy. Im sure he is at least luffy level or higher(probably higher). He has been trained by dragon for many years, he has been fighting/training longer than luffy, and he was stronger than luffy when luffy was a kid still.
Both OP and Naruto are at points in the manga where I really dont want these breaks to happen. IM just glad they happened on different weeks.
