It's fair when you're discussing potential available to a character without ass pulls and handouts. It's a what if scenario and how they'd fair if developed or at least how I view it through my lens.
Inojin parents had no potential to begin with in a series where they were shafted, introduced and abandoned. So what purpose is it when even the author provided no references to their potential?
The only one who has that was Himawari, Sarasa,Mitsuki, Shiniki and Boruto
I could understand these characters maybe, even when it all boils down to headcanons ans what ifs. Which is easily a way to make shit up.
Sarada potential for Rinnegan!
Boruto potential for Jinchuriki!
X’s potential for Y.
There’s no point. Just like those threads about Sasuke learning sage mode or Naruto’s potential at gaining Rinnegan.
It’s pointless. Especially for minor characters with no discerning role aside from Son/Daughter of that character you may remember.
