ahh i read the other anon's take on an atla au and i liked their adaptation, but i had pictured shouto as the avatar instead in my head. like endeavor still is the firelord and i like the idea of him marrying a water tribe princess but consider,,, the previous avatar was nana, from the earth kingdom whose best friend is the air nomad gran torino, and that's how she meets air nomad toshinori who cant actually bend, but has a big heart and takes him under her wing. needless to say, she dies
(didn’t have space to mention it previously) but toshinori is so strong he somehow fools everyone into believing that hes an earthbender. as there’s no avatar to stop him anymore, endeavor is free to do as he wishes. before nana dies (and in the time todomama is pregnant) he’s warned by someone that she’s going to die. so this is kind of perfect for him, he has the opportunity to have the next avatar be his son. so he does the unthinkable and a warning to his kingdom is sent that every pregnant woman that gets into labour when nana dies is to be killed with her child. the fire kingdom keeps a tight register of the children born from then on, shouto is born about two days after that, and it takes about a week for the news to reach the fire kingdom that effectively, nana has died, but no one is sure when, as previously all the kids that were born during that week (but shouto) were killed, enji is sure his child *has* to be the avatar, but as soon as shouto can walk hes taught fire and water bending techniques. enji is still the abusive asshole that hes in canon, and his other children suffer neglect and his wife is abused, but he controls the fire and water kingdom so there isnt really anyone that can do anything to prevent this. after nana dies and enji takes over both kingdoms, the only reason he can’t take over the air nomads and the earth kingdom is toshinori. he somehow has never been able to defeat him (he doesn’t know all might is a non-bender). toshinori inspires people in a way no one has before and has good people that surround him, and can take down good benders any day any time. enji kind of is scared of confronting him himself and loosing. toshinori keeps enji off of the air nomads and earth kingdom.
meanwhile, as enji’s army fights toshinori and co., shouto has been able to bend water since a young age, but can’t seem to be able to bend any other element. but one day while playing with his siblings he bends his sibling’s fire. todomama sees this and is terrified of what enji will do to shouto now. the training was already too hard for a five year old kid who couldn’t yet bend fire and for so didn’t actually trained with it. she makes him and his siblings to never tell anyone about shouto bending fire, and shouto swear that hes to never use any other kind of bending besides fire.
enji is so mad. shouto is almost six and he hasnt shown signs of being able to bend anything but water. he blames todomama for this, saying that he spoils him too much, that if she wasnt so weak and also cared about her family and their kingdom shouto would be able to bend anything by now, and todomama slowly builds up the idea that maybe shouto isnt the avatar, that maybe the avatar was one of the kids he killed. enji can’t tolerate that idea, and when shouto is eight and cant bend anything else.
he decides that he cant allow anything to get in the way of his world conquer, its already too difficult with toshinori. so he decides that hes attacking the air nomads next, where the next avatar would be born. but he cant attack them with toshinori still defending the air temples. so he makes a temporal alliance with some weird guys who claim to be able to take and give bending powers as they wish. they send their leader to fight toshinori, and meanwhile enji sets to attack the air temples.
izuku is eight years old, and he also can’t bend. hes really good at making plans tho. he has grown with his mum in the air temple all his life with his friends iida and ochako. ochako is really cool beacuse she can make things fly with her bending techniques, and iida prefers using air bending to reduce air resistance and go fast. iida’s dad builds machines while his mother is an air bender, he travels a lot with both their parents while his brother fights in toshinori’s side. his father sells some stuff for the fire nation, because he believes if he doesn’t, then someone else would, and it helps toshinori’s side to know exactly what is attacking them and have better equipment than what they have (much to enji’s annoyance they somehow seem to be always one step ahead) that’s how they know that the air nomads are to be attacked soon, by trading information with some militar that knows his wife is an air nomad but doesn’t know about his children.
they return to their temple to warn people to flee. but there’s little time, not everyone can scape. present mic, an excellent bender, decides to stay and defend them while some attempt to scape. aizawa meanwhile arranges a plan to save the kids, as they know they are going for them thinking one of them is the avatar. shit goes terribly wrong and only few manage to scape without enji’s army noticing, among them, izuku and friends with aizawa’s help.
on toshinori’s side of the story, hes battling afo. afo tries to take his bending away, and to his surprise there’s no bending to take away. this to toshinori’s advantage, knowing that hes the one who probably killed nana, he fights with all he can, and even though afo manages to fatally wound him, he defeats afo. (or so he thinks). by the time he knows the air temples have been attacked, is too late. but aizawa finds him and informs him that is quite possible that the next avatar is among
enji is so mad, because he didn’t find the avatar among the kids he took from the air temple, and even though with toshinori weakening hes managed to control part of the earth kingdom, there’s rumors of a kid that seems to be able to bend different elements being thaught by toshinori (being nana’s apprentice)
everyone believes izuku is the avatar, and hes freaking out bc he knows hes not, but all might tells him that rn he gives people hope, and that has always been the avatar tasks, so for now there’s nothing wrong with pretending. and of course, the only ones that know hes not the actual avatar is todomama and kids. until one day enji is particularly mad and lashes at todomama, that is. he attacks her with fire, and shouto gets in the way to protect her and directs the fire towards enji and himself (getting his scar). enji is now even more furious and lock up todomama for her betrayal to the fire kingdom by hiding the avatar. shouto is mad ofc, and so he decides to never use his fire bending again. enji is so mad, bc now he has an avatar that only bends water. the only reason shouto still trains his bending (starting earth) is bc enji still has power over todomama.
his siblings have already left, save for his older sis. she then receives a letter saying that todomama isnt under enjis control anymore, that shes been banished, along with what seems to be evidence. she then convinces shouto to scape and he does. shenanigans ensue from now on, he joins toshinori’s army and meets izuku “the avatar” while knowing hes not. it might be somehow ridiculous bc even izukus childhood friends like ochako believe him, and shouto never says anything about it. tododeku also ensues and shouto tells izuku the truth and izuku is so embarrassed bc he knew all long (even though izuku tried to impress him with his “bending” several times) but shouto finds it kinda cute. izuku “its your power” helps shouto understand that he needs his fire bending if hes to defeat endeavor, and shouto helps izuku deal with all the guilt he feels for lying to the entire world, assuring him that it was the right thing to do at the time.
i cant’ believe i constructed an atla au from my only previous idea that was “what if shouto is the avatar” when i have homework to deliver like, today.
holy shit anon this alternate atla au is intense as hell ahhHH ((ty for taking time to construct it even when you were busy))
i like the idea of shouto helping the idea that izuku is the avatar by using his bending to make it seem like it was izuku who did it??? kinda like what conan does for mouri in detective conan, except both parties know whats up lmao. ppl come up with rumours that izuku only bends around shouto bc izuku wants to woo him,,, like, to show off to a love interest. tddk are super embarrassed, but they’ll take what they can get because they’re helpless and can’t think up any other reason.
