Thanks. But the worlds wants do-ers than thinkers and I'm more of a thinker.
I have rough ideas for my next avatar along with a whole story behind him.
I haven't read the post-series comics of Korra so I dunno much about what happened to her after she and Asami left for the Spirit World. I think the comics say she came back but for the sake of my fanscript at some point Korra had to return to the Spirit World and was never heard from since. Given no one knows if she's alive or not and that given her spirit cannot stay in the Spirit World means it is unknown if she's alive, dead or when she died for the Avatar Cycle to continue.
Over time Varrick Global Industries collaborated with Future Industries to establish new power plants across the world that uses the spirit vines to provide "clean" and "safe" energy to the world, bringing it into a dieselpunk age (without the diesel). The City of Omashu being one of the few Earth Kingdom cities to have one which revolutionize the city, allowing immigrants from the other kingdoms to find new lives there. So while Omashu is still an Earth Kingdom city it has become more like Republic City over time.
I imagine the new Avatar looking a lot like a cross between Haru and Bolin. Wearing green workers overall and white shirt stained with machine grease.
The Avatar, is a mechanic at Omashu's power plant. He knows a lot about the dieselpunk machines that surround his daily life. His best friend is a waterbender who is more for healing than waterbending and is training to be a doctor. (I dunno if the stigma of only women should be healers is still around or not but if so he is trying to break that barrier). After a work-related accident his friend gets severely hurt. In his panic he tries to clean the wound with water and when he noticed the water began to glow he attempted the same healing methods he observed his friend done before and manage to heal him. Surprise to learn he was both and earth and waterbender they were quick to realise the potential of him being the Avatar. Unlike Aang who was told he was the Avatar at a young age or Korra who discovered and embraced her Avatar identity at a young age, this Avatar had absolutely no realisation he was the Avatar until he healed his friend with waterbending.
Over time the finds out he cause of Korra's death, a sort of cover-up in the Spirit World. Korra finds out that the spirit vine power plants were causing some sort of pollution in the Spirit World and was killed to prevent this from becoming public. Given Asami and Varrick are personal friends to the Avatar and the ones who constructed the power plants I doubt they were the ones who would kill her, though perhaps Varrick would be a suspect.
So the new Avatar starts a campaign to stop the use of spirit energy and to bring awareness of the pollution in the spirit world. However given the worlds reliant on spirit energy and Varrick Global and Future Industries monopoly on spirit energy this makes him an enemy to them.
The only ones who agree to the Avatar is the White Lotus and the Air Nomads who were lead by Tenzin's great grandson. However the Air Normads ideals turn out to be rather extreme and destructive. This is because the leader of the Air Normads isn't just a decendant of Aang but also the reincarnation of Unalaq making him the Dark Avatar. Despite being Air Normad he is still driven with the desire to ruin the world just as it's the Avatar's duty to protect it.
That's all I thought up so far.
