He proved he was superior in the movies to Johnny, Chozen and Barnes. And in the final episode of the 3rd season, he has Kreese beat until his daughter and Miguel showed up at the dojo and he showed mercy. All that is left for Daniel to do now is beat up Silver which we hope he does in season 5
What is his record against each of them? All of them kicked the crap out of Daniel the entire movie, before he pulls out a win at the end. In the case Of Johnny you can argue that most of that happened before Daniel was trained, and he’s been fairly even since. But Chozen was beating up Daniel after he had been training with Miyagi for a while. Daniel won the fight to the death, which is his only impressive win, but he also lost to Chozen in a rematch during Cobra Kai. Chozen even got his revenge by doing a honk. Against Mike Barnes, he has no argument. Barnes wasn’t trying to win, and Daniel only got in a single hit. Barnes destroys him in a street fight or tournament.
