The Best Why Is Naruto's Jinchuriki Form Different References. My personal headcanon is that its a heighened biju mode naruto enters because he's a sage. If you go through the tailed beast mode section of the jinchūriki forms, you can see that (emphasis mine) naruto has not been able to fully recreate kurama's form.

Strangely enough, that rarely happens in the story. This inhumane treatment of jinchuriki makes no sense, especially since a lot of them are mere children. Kon has extremely high powered physical strikes.

Obviously as he doesnt have an actual monster inside him, minato does not; At first, this was because the fox would not cooperate with him, causing all attempts to turn into it to result in a miniature, comical version of the beast that could not. His pupils become slitted, and his irides will change from blue to red.
There Are Two Theories About Why Naruto’s Transformation So Special And Different Than Others.
The main reason why naruto’s transformation is different. I presume it's just a visual thing for them. After all, they are bonded with ancient monsters.
The Prior, On The Other Hand Can Be Done By Letting.
The adults of the world should be smart enough to separate a human from what's sealed inside of them. My personal headcanon is that its a heighened biju mode naruto enters because he's a sage. Strangely enough, that rarely happens in the story.
