At Dressrosa Arc Usopp directly hits Doflamingo from a large distance. Was that observation haki or just a fluke?
Usopp literally awakens haki to shoot Sugar.
Well from what I've noticed it seems that there are different categories of observation haki. Ofcourse this is just pure speculation. Yes usopp awakens haki it's not by chance that he shot sugar... all the vigorous sniper training he had for two years plus the seemingly difficult situation that he faced in dressrosa forced his haki ability to "awaken"
Usopp shot sugar and awakened haki
usopp unconciously awaken his aura haki when it needed saving luffy. the conclusion is all shp becoming stronger when it comes to save friends.
yeah all of em are getting stronger by each day
Even Chopper can now transform in that monster form in a controlled manner.
He awakened his kenbunshoku haki when he was trying to fire at Sugar to save Law and Luffy.
What do you think?
