It’s an interesting idea, let’s analyze it one by one.
1. White skin and yellow hair.
There are also ninjas from the Kingdom of Wind who have this kind of appearance, such as Temari, and most men from the Kingdom of Thunder have dark complexions.
2. Abnormal speed
Raikage's speed is due to the instantaneous body technique blessed by thunder escape, and is not a time and space ninjutsu. The flying thunder god of Namikaze Minato belongs to the time and space ninjutsu. Different properties.
3. The pressure of space ninjutsu
And unlike the heavenly sending technique of the Land of Thunder, Flying Thunder God has no pressure on the human body. This can be proved by the fact that the water shadow can be teleported during the Ninja World War. , but the requirements for activating Ninjutsu are very high.
4. Physical fitness
You can actually tell this by looking at the muscles and size. Minato is so elegant, so he is obviously not the type of muscular man from the Land of Thunder.
The last and most important thing to add is that Minato has never used Thunder Release, so the possibility of being born in the Land of Thunder is almost non-existent.
