A battle of wits means a fight that relies on intelligence. The smarter you are, the more likely you are to win.
But what if your opponent is much smarter than you?
Then you make them dumber, bringing them down to your level, or even lower. That's the ultimate battle of wits.
[Idiot-Inducing Halo], an ability that makes everyone nearby as stupid as its owner. As long as the opponent is more foolish than you, you can crush them with your intellect.
Its only flaw is that it doesn't distinguish friend from foe...
Our protagonist was born with this halo and reincarnated into the body of Zeppeli, who was on the verge of death.
From then on, the world of JOJO had a new character who was completely out of place.
The villains' opinions of him:
Wamuu: "He's a powerful warrior... I think..."
Kars: "When I'm around him, I feel like an idiot. Of course, so is he..."
Dio: "Wryyyyy! A loaf of bread coated in sweet cream on the outside, but hiding devilishly hot spice inside! Get lost!"
The heroes' opinions of him:
Joseph: "Oh my God! What are you doing?!"
Jotaro: "Old man, can I beat him up? I think Star Platinum can't hold back any longer."
(This story calls Joseph JOJO. OOC warning.)
