2. People bring up Conqueror's Haki all the time AND USE IT INCORRECTLY. It works on THE WEAK WILLED ONLY. Meaning, if you have any type of notable willpower (aka not a fodder fisherman or pirate) then it won't do jack to you, Naruto is not even gonna feel its effect.
This may be resurrecting an old thread, but you're pretty wrong about point 2. Pre-time skip Luffy heavily shook up the majority of people in the Marineford War including the Admirals and Sengoku. This was before he even knew how to properly use Haki. He shook them up and they themselves are all familiar with Haki, whereas Naruto has no idea what it is. He would completely mess him up with a full blast.
you kind of did resurrect it unnecessarily, as the correction you're doing doesn't seem right to me.
Conquerors haki is an extremely rare phenomenon, and luffy's displaying it surprised the admirals and sengoku. It later also surprised zoro, sanji, and jimbei, but it doesn't mean they were affected by it.
A nearly perfect parallel will be ichigo arriving at rukia's cell, with byakuya and ukitake talking. They were both surprised by his captain-class spiritual pressure, but it didn't bother byakuya the slightest when they fought.
Naruto may sense luffy is doing something weird, but with his willpower, he isn't going to be bothered. tbh I don't think it was a great addition to the thread, still, we will wait for other op readers to post.
No. If you recall, once Luffy learned how to control Haki, he could choose who would be affected by it. It's the whole reason he had to train in solitude amongst the animals. Rayleigh said he needed to learn to use it so he wouldn't hurt people unintentionally. So when Sanji and Zoro were surprised, it was because they were witnessing it and not being hit by it. Sengoku and Garp (Marines who were always chasing and fighting Gold Roger and Rayleigh mind you) were both affected by Luffy's Haki. If seasoned Marines who would fight the previous King of the Pirates were shook up by an untrained blast of Luffy's Haki, Naruto would stand very little chance against post time skip Luffy's Haki.
