Minato is the most original shinobi
It's true. The only man without a KKG to be so original. I mean, what a ****ing genius. Let's look at the things he invented shall we?
After observing the TBB just ONCE, he was able to create the rasengan, the hardest form of chakra manipulation. This takes skill, and what skill he has. Gifted.
FTG? I don't know how he created this, but it's amazing. I really don't know what Jiraiya was doing with Minato as a kid, I mean the guy created all his jutsu? What a boss. Haters will hate man. Minato wasn't born in some clan, wasn't blessed with a KKG or taught anything which contributes to his fighting style. The FTG is what makes people mad. People think that's all he has, but hey, if FTG and a kunai to the neck is all it takes, then why would he overexert himself? What has Obito been doing over the past 15 years? Again, originality; 100%
S/T Barrier: I think he created this because he knew what a threat the TBB is. I also noticed people didn't know Minato created it, but he did. FTG is the parent jutsu.
What makes his techniques so original is he's probably the only person who uses and relies on the techniques he created. What happened to Kirin? Oh yeah, MS.
So guys, let's grasp the simple fact that Minato is the most original person to have ever lived. The one man who was only taught seals by lady Kushina.
