The original midas wrote: I saw the word copy but no reference if he is talking about using Sharingan or just copying the way Minato used the technique or the level he performed it at in comparison. Also depending on where you read chapters from they could have different words in translation so need a verified original correct translation source. So that's not really an proof.

My proof isn't in a chapter but on the Sharingan page of this website. It kinda breaks down how the Sharingan works and its capabilities? Good information to know. Anyways here is a line from that page.....

"Sharingan users need the prerequisite abilities before they can mimic a jutsu they have seen, and for that reason they cannot, for example, reproduce kekkei genkai abilities they do not have or nature transformations they haven't learned to perform."

Bolded font is important to notice because that is also referring to the needed chakra control and level of shape transformation required to perform an A-RANKED technique which is Kage level in the difficulty and power needed in learning the technique. Sharingan would probably help them understand the technique but because of how it works they ain't gonna just replicate it on the spot thus they would not be copying the technique but actually learning it instead if they could at all. This is most likely the reason Medical Ninjutsu isn't shown being copied by the Sharingan. Once again looks like a simple technique but more complicated than it seems.

Also when you copy something you don't need to learn how it works or how it was made its just copied. When you need to put in time and effort in something that means your learning how to do it step by step.

You need to make sure when you use words know the definition of them. You realize the Sharingan uses the word "copied" even though the user still needs to have the skills to use the technique right? The Sharingan just allows you to understand how jutsu work but you still need to be able to do it.

Which is why I used the word "copy." Because in the context of the series, that's exactly what it is.

Anyways, I gave you proof, Kakashi says the Rasengan is at a level that he can copy. You on the other hand, have no proof whatsoever. Not a manga chapter, not a page, no databook entry, not even a filler episode. So if you don't have any actual excerpt from the series that gives your argument some legs to stand on, then that's that lol.
