@taichokage: how is coby below pre timeskip luffy? coby can use geppo and soru masterfully not to mention his haki destroyed a big metal circle in one hit. coby is captain (aka pre timeskip smoker level) even marineford luffy lost to smoker (mainly due to him being a logia but still coby has busoshoku to even that disadvantage)
sandersonia had poor haki. coby's haki looks more on sentomaru's level.
Well in my opinion current coby is above pre time skip luffy.
His mastery of haki and soru is an extreme advantage. He took out the giant metal thing with the wind from his fist. It wasn't even like a forceful connect. He should be able to more than damage everyone.
The only problem comes in is with lucci because coby has no real durability feats and putting him up against a speedy tank like him really is a bit much.
Coby still doesn't have enough feats to put him above Pre Skip Luffy, having Haki doesn't give an automatic win, Enel and the Boa sisters are proof of that. Also Lucci is no pushover, VAs revered him and were surprised by his defeat, he single handedly brought Luffy to the brink of death with physical attacks alone.
