Dubois, who's 27, thinks Joshua might struggle mentally if they fight again. He said:
"He'll have a lot of demons playing on his mind. Who knows if people are talking him into it, I don't know. I know from my side I'm ready to go out there and show the world that I'm the king."
People are talking about a rematch happening in February. Dubois seems up for it, but he's got other plans too. He wants to fight Oleksandr Usyk if Usyk beats Tyson Fury in December. Dubois lost to Usyk before and wants to set things right.
"That's unfinished business. I want to get that one right. I want to do it properly and finish him. It will be a good fight, a unification fight, that's massive."
Dubois and Usyk fought in August 2023. Usyk won by stopping Dubois in the ninth round. But there was a moment when Dubois knocked Usyk down. People thought it was a body shot, but it was called a low blow.
Joshua, known as AJ, is trying to get back on top. He wants to be world champion again. He recently named a heavyweight he says he "ruined with one punch".
While Dubois and Joshua might fight again, boxing fans are also waiting to see if Usyk and Fury will have their rematch in December.
