Re: no one has pointed this out yet.
That is NOT the Flying Thunder God technique and that's a fact. Saying otherwise your knowledge about the Narutoverse is very limited.
The FTG is based around a certain seal. By throwing a kunai with that seal on it, Minato could transport/teleport or whatever you want to call it to that kunai. It's a space/time ninjutsu, which means there's no physical contact of any kind between two destinations. As Karin said when Madara appeared he just came out of nothing. Same with Minato, he doesn't run or anything, he literally is one moment on that spot and then on another, he doesn't even need to move.
That's why Minato had his kunai's all over the place, so he could warp himself there in a second.
The only way Naruto could have used the FTG (put aside the matter as how could he possibly learned that technique) is if Kisame would have had the seal on him and how is that possible? It is not.
Body flicker is a technique every genin can use, it's just high speed movement where most of your movements are covered by things like leafs or sand.
Why he was compared to Minato? Outside the fact that they do that all the time, Minato was due to his FTG considered the fastest ninja alive and when he warped multiple times the only thing visible was his yellow hair in a flash. Hence the name Konoha's Yellow Flash. Naruto was completely yellow/gold and he moved so fast that he also looked like a yellow flash. That's it.
