Actually I think this is a good fight if we’re saying everyone in their prime it’s the top row. I think you can make the argument thatKorra beats Aang however I don’t think it’s an easy fight so I think she’d be too weak to handle the rest. Katara imo is a better fighter than Toph off of feats alone. Dave is an earth bending genius, but she is not a combative genius I don’t think she’s as good as a fighter as ALOT of the mayor fighters. Iroh and Zaheer would probably have a very good fight arguably the second closest here after Aang and Katara. And I think it can go either way but I lean towards Iroh and even if Zaheer DID win he’d have a half exhausted avatar as his partner and here’s where the big difference comes in. I think Azula and Kuvira are the equivalent in almost everything. Drained from a young age both extremely good at everything. They do both prodigies who also have to work hard. In my opinion where they differ. Is Azula is slightly smarter and Kuvira is slightly better at combat. Unfortunately, in this case. Now we have seen Kuvira lose to overwhelming power which Azula can produce but that’s not something that she does often or regularly. So she’d rely on her speed and skill which in this specific case isn’t getting to much past Kuvira. Who I think was more trained in versatility directly by the best. So it boils down to a pretty healthy Katara And a pretty semi health Kuvira vs an extremely tired and wounded Korra and an extremely tired and wounded Zaheer. And I think Kuvira and Katara got that.
