And why exactly we are discussing OP here? It's not like KG users get their control on KG in one day either. Both writers use it as a power boost be it KG or a devil fruit.
not all devil fruits granted an ability to use in battle, that's what i wanted to say, its all up to the user how they utilize in a battle, like chopper fruit for example and bon-chan fruit, know what i mean ?
You are clinging on the details about OP which are not even being challnaged. I said that their control was not perfect but they were bale to use it just like newly awakenned KG. so why are you repeating the same thing again?
oh am sorry about that, since i just know that you will probably mention kaku and califa so i just get carried away while explaining how they make use their DF in a battle,
And it's nice of you to acknolwedge that Luffy's second and third gear were rather abrupt as he was almost all the time busy in other things except for the short journey from Long Island to water 7
well everyone who watched OP will surprise when they see luffy did that out of nowhere
When did I say Haki is sudden? I asked you if you would call it that? Kurama is not sudden either and it took extraordinary efforts to gain its trust and respect and a long time. Naruto is 16 currently and has been through various phases.
oh yeah you never said haki is sudden, i just stating the obvious,
if you put it that way both mito and kushina have kurama inside their body longer than naruto, and none of the manage to gain kurama trust, that's why i said its all about plot this and that,
Naruto has always learned things a bit faster once he understood the basic idea - He learnd shadow clone jutsu from forbidden scroll in few hours. he did learn Rasengan in one week- and surprised Tsunade. He learned sage mode and wind techs in relatively short time as well- his training is always completed in battle field. Even Bee who knew only knew him for a short time realise Naruto is more likely to learn faster in the field than in class room atmosphere.
that's just like luffy and his gear 2nd
First few times Naruto didn't understand what was going on with Kurama either. Jiraiya started to train him for control and finally Bee trained him for it as well. And he still hasn not gained full control. He could hold it for few minutes only.
well am pretty sure when he fight sasuke kishi will just skip the detail and let naruto mastered the bijuu mode
And Nah the first time we got the glimpse that Luffy had some hidden power was during his fight with Duval's ox.

it wasn't named there.
really ? i thought that ox is just chickening out
Kabuto's power ups were always artifical. He was popping pills while fighting with Tsunade for the very first time as well. Oro is all about experiments and at least he had lab and researched for years. Kabuto is reaping the crop he grew. IN OP as well, Pacifistas are nothing but scientifc experiments. You didn't question survival of Franky and his making himself a cyborg in that conidtion and living on Cola fuel.:|
but that just to sudden, i mean oro can't even handle it, and kabuto take over oro role and suddenly he learn everything in such short time,
oh and about franky, its the same thing like we questioned rinnegan origin
Danzuo VS Sasuke - well Sasuke did get help from Tobi lurking in back ground. Danzou was distracted half the time and he didn't use Shisui's eye even because he ws afraid that Tobi could make his move anytime. He thought he could deal with Sasuke without it and wanted to preserve it. Then I have to check the manga as I haven't done so recently but wasn't Karin there to give him power boost before he met Danzou
yeah karin was there, but he only boost sasuke chakra and wound not his body endurance as he already get beaten to pulp by A and choujurou, let alone the susano'o side effect
So yeah why it's an OP discussion again? You understand that these are two different mangas that have their own pace and story to follow, don't you.
IDK, blame that kid who bring up one piece in this thread, i merely respond to what you said, thought there are things that not necessary that i wrote in my earlier post.
