As i said, im not sure if that lowest panel is enough to assume that he penetrated luffys haki. Incase u dont understand let me "simplify" for you. There is no proof that Luffys haki was penetreted. Ergo even if he coughed blood, its still no valid conclusion, unless Luffy, the grandson of garp the fist(haki senpaiaia) 400 mil beli bounty, who is about to take down the one and only Don Doflamingo. Is beaten by Bellamy a somewhat fodder character, who Luffy himself one shotted in the Jaya arc. Taking in consideration that u didnt comment about my "deduction" and argumented with one flawed one liner. Then ill assume that u belive that Bellamy somehow have stronger haki than Luffy. Lal. I agree that its weird that Luffy coughs blood, but there ahould be no way that Bellamy is stronger than Luffy. So my "argument" was based on this. So i said that either Luffy intentionally weakened his haki or bellamy have beastly haki. I know ur kinda new to the wiki, but next time try to come with something more than a one liner.

Ill be inclined to belive that as @nutterbu.. Said the momentum of his spring could have a say in it. I hope that a thing like this isnt the case, cuz if a fodder character can beat the protagonists haki, who is about to fase a yonko in a couple of arc. Then Luffy shouln't be able to even compete in the next couple of big fights/wano etc.
