My theory

I think after they are done this whole Kreese arc, they will start going for maybe a tournament arc where it is no longer the All Valley and they take on the statewide tournament, then nationals, and eventually worlds. I would think that it might be cool to do that. We could maybe see Chozen again if he has a dojo of kids, or Aisha and bring her back for a bit because she has to fight against people with her new dojo. It might be bad on character building and maybe people wouldn't like the constant fighting but i think they could fill that part when they go to these places and have interactions with other teams before they even get to fight them. Or maybe it is a series of 2v2 tournaments and we get to see Robby and Miguel fight alongside one another. I don't even know if they have 2v2's in karate but i think that would be cool.
