As a kid ai liked Yusuke Urameshi. Most people didn't know who he was for me to even advocate for him but when I spoke of him I would say Yusuke be beating ass he's dope. I think most fans can relate. If your talking to someone about Goku or Naruto they might say they pretty admirable characters who have cool fight scenes. They might even speak on their character and how they might have inspired them as a kid. Alot of anime character were like pseudo role-models. At all different ages we go through phases, like doing the Kamehameha in class ending up to where their just memories and while we might keep their ideals in mind we know you can't go through life acting like an anime character.
Zoro fans on the other hand.
Sums it up pretty nice. Like I think if you didn't know about One Piece and met a diehard Zoro fan they'd say:
He's stronger than the captain
He's the backbone of his crew
He one shots everything
He's ronically like a God
You shall not slander him
Me and him both want swords in our mouths.
Same can go for Itachi fans. Like nobody would argue for Luffy bearing two yonkous or fighting three admirals at the same time. Though Zoro fans and itachi fans would be like Itachi can solo the akutski or Zoro will kill Kaidou. Even after Kaidou one or 2 shot Zoro this didn't disenfranchise Zoro fans they still believe in a one on one fight Zoro would OneShot. Itachi said out his own mouth he couldn't beat Jiriya them Nagato says he couldn't have won if Jiriya knew his secret. Means nothing to those fans.
