[Apple Knight]

What was Minato's most intellectual achievement?

 

[~Ethereal~]

That spam, when he was against the masked man in Konoha.

 

[Darth AniCetuS]

When he kicked Obito's ass for the first time with smart use of his FTG.

 

[InfiniteDeath]

Creating the Rasengan?

 

[InfiniteMugen]

When he kicked Obito's ass for the first time with smart use of his FTG.

From what we've actually seen I'd say this. This showed quick thinking, quick observational skills, and the ability to quickly put that knowledge to use.

Bar creating a Rasengan? Nothing impressive.

 

[kiiro]

Why you ask?
