Mama!Sabo AU

Aka how Sabo became the mom of his alternate self™

——————————————————————

So basically Sabo gets transported to the past, or atleast he thinks he did. He actually transported to an alternate dimension, which is really similar to his own but with tiny little differences.

Sabo is currently a woman cause he was undercover and Iva turned him into a woman before some shenanigans happen and Sabo gets yeeted to another world. At the start, he tries to find a way back home. He explores a bit, and realizes he's back in time thanks to a newspaper.

There he meets younger versions of himself and his brothers. Since Sabo is somewhere during the Wano Arc, he has already gotten his memories back and is now being really emotional when he sees Ace. Sabo then very patiently gets the alt!ASL brothers trust cause he wants to protect all of them. Yes even his younger self since he now sees the younger blond as his brother. He did tell them the truth, that he's the older version of Sabo (not true, but he doesn't know that), and he told them that cause he didn't want to lie to them.

Alt!Ace and alt!Sabo think he's gone crazy, only alt!Luffy believes him. But here's the thing. He's currently a woman, and a very sweet and nice one at that, so the alt!ASL brothers are more willing to trust him. Especially since our Sabo reminds them of Makino. Even if they still think that Sabo is a little crazy. Of course, Sabo eventually manages to convince alt!Ace and alt!Sabo that he is 'future' Sabo. So the four become close, so close that it seems like Sabo has always been a part of them.

Sabo feels responsible for them and acts like a complete mother hen. He does know not to smother them, but he does act like a good brother(mother) to the boys. Since he's a woman at the time, the boys can't help but think of Sabo as a mother figure, or as a big sister. He's just so sweet to them and is so. soft that they can't help but think that way

(it's cause Sabo feels guilty that Ace had to raise Luffy all by himself. So he's trying to make up for it by acting like a proper 'big brother' by raising them. He ends up being more of a mother hen)

As time goes on, alt!Ace and alt!Sabo find out that Sabo is still trying to find a way back to his 'timeline'. Neither of the two want this, and keep Sabo distracted, by acting clingy, which causes alt!Luffy to get clingy as well. Alt!ASL follow Sabo around like little ducklings, which is extremely adorable.

One day, Luffy calls Sabo mom. Which cause Sabo to tear up and become so happy. He didn't realize he was being a mom, but he doesn't mind that his little brother sees him as one. Really, he's just happy that Luffy sees him as a parental figure(also angst that Sabo thinks that he doesn't deserve this second chance to take care of his brothers, since he failed to do that in his own past). This starts a trend, where alt!Sabo and alt!Ace also start calling Sabo 'mom'. Sabo thinks their just joking around and still refers to himself as their 'oldest brother'.

Sabo's just so happy and absolutely loves his brothers, even when they call him mom. He's blissed out, and has completely forgotten to search for a way back home.

Alt!Ace and alt!Sabo are just happy that Sabo has stopped searching for a way back. They're never letting Sabo go, he's their mother now, and no one will take him away from them. Alt!Luffy is also just as selfish, wanting to keep Sabo in their 'timeline', but is totally fine with following Sabo back to his 'time' even if it breaks the whole timeline.

Alt!ASL one day bring Sabo to town with them. Sabo has been gathering information and mainly hid from everyone, so no one really knows who this strange but beautiful woman is. All they see is a woman with soft, curly hair parted in a similar way to Ace, with brown eyes similar to Ace. She's got blond hair, similar to Sabo, with rounded features like Luffy and Sabo. And when she smiles, she smiles just like Luffy. Her skin was pale like porcelain, the only thing out of place being a horrible burn mark on her face that only made her look beautifully fierce.

The demon brats call her mom, bringing her place to place, and soon, introducing her to Makino. They overhear from the blond brat about her having amnesia, only recently gaining her memories and theories fly.
