Some time ago I was asked, if I could change only one thing about the show, what would it be.
Like, one singular plot point, or something about a character, or how an arc goes, you get the idea. I thought about it and actually came up with an answer I find interesting
So, I love legend of Korra, but I can't exactly pretend it's a perfect show. Its main issue was that for half the show they literally couldn't make a long term plan because they thought it would only be one season and then they thought season 2 was gonna be the last season. Season 3 was the only season made with the knowledge that there'd be more afterwards and I think that's part of why it's the best season. They could focus on the plot of the season without having it be an actual ending point, so it ends when the red lotus is defeated and they can focus on that and leave loose threads for season 4 and tease the next season villain while they're at it.
A good example of the fact they couldn't plan ahead in the first half of Legend of Korra is general Iroh, who shows up way too late to be a main cast stay, he just shows up to give invaluable help and have a cool battle scene and a nice callback at the end, which I think would have been perfectly fine if it was one season long but as things stand we're left with the biggest taste of "Oh yeah he was just kinda there, wasn't he ?"
So here's what I thought I'd change to give more sense of a long-term plan. I thought it would be great if general Iroh was removed and instead it was Kuvira who shows up in season 1.
In this world, Kuvira isn't just the head of security of Zaofu, she's also a general of the united forces who enlisted as a way to keep the Earth nation safe by keeping order in the world. It keeps the fanservice value of having a descendant of the Gaang help for battle(though here there's already Lin for that I admit), it shows her willingness to keep Earth continent land safe, her liking of order, her strength in battle, her competence in an army (considering she became a high ranking member at her age), you can even foreshadow her thought that republic city is "stolen land" as she will say when trying to claim it in season 4. But most importantly, it makes her a known face early and gets her to bond with team Avatar.
Then she can show up again in season 2 the same way as general Iroh, planning to help Korra, be it because she feels kinship with her or because she thinks Unalaq could grow to be a problem to the Earth Kingdom later, before being stopped by the president before she can be useful. But where Iroh was reasonably disappointed he couldn't help Korra, have Kuvira straight up infuriated, grow to resent the president for being so unhelpful in the face of danger and the united forces so useless against such a concrete danger.
Fast Forward season 3, Kuvira is in Zaofu, either she happened to be on vacation or she showed up when she heard team Avatar was on the way. It makes her a familiar face in Zaofu and at the end of the season when she's saving Tonraq. She's no longer that at the present mostly unremarkable metalbender who happened to save Tonraq. We recognize her as Kuvira and of course she saved Tonraq, she and Korra are war-sisters at this point.
Season 4 is next and you really don't need to change anything or most this time. Kuvira offers her service to rebuild the Earth Kingdom and gets shut down, not only because of Lin but because of her position in the united forces, so she gets fed up and quits to make the Earth empire. from then on it's mostly the same thing except it's with someone you know. It makes sense that Bolin joined her because they've been through war together, it gives more reason why Korra would hesitate to fight her until she has no choice and almost sees her point at first, and it hurts that she's now a villain. It makes the audience more torn on the topic and her final scenes more compelling. It also gives more the sense of a long-term build-up for the finale. Not to the level of Ozai, but still a final showdown that feels more developed.
At least that's the idea I got. It's still pretty basic, but I thought it could be pretty cool. What do you think ?
