Here's another cross post from Reddit, where I discuss the idea of legacy through Izuku, and whether or not he may have a successor in the future as well...

The Tenth Bearer

(Inspired by Spider-Man: Into the Spider-Verse)

What if we were to give Izuku Midoriya a successor?

Okay, hear me out: during the Vigilante Deku arc, we can assume that Izuku was gone for a long period of time, roaming around the country, fighting bad guys wherever he found them and tracking All for One's agents, right? So what if, during that period of time, he ended up picking up someone and training them as his successor, like All Might had done for him?

Essentially, I want to give Izuku a Miles Morales to his Peter Parker. Besides, legacy is one of the biggest themes in MHA, so I thought that this would be a good way of continuing that.

I'm currently imagining this successor character to be an OC, probably a female in order to give the female cast some variety, and having her backstory to be something like Deku's as a form of parallelism. If I were the one writing this, I would have her personality to be rather plucky and enthusiastic, but also all about this hero stuff, even in a society that has lost all its faith in heroes.

I can imagine this character being a year or two younger than Izuku, probably at the same age as Izuku was when he was picked up by All Might, and would have picked up on Izuku during the news or something, probably when he was saving Eri from Overhaul. Since then, she has idolised him, and when hero society collapsed, she found one of his old costumes that was lost during the chaos and took it for herself.

She'd eventually meet Izuku and ask to be trained by him, only for him to turn her down since he's in his Batman phase and is really grumpy and edgy right now, and also because she reminds him too much of himself when he was her age. However, after a lot of pestering from her, as well as her following him around (which he would find impressive because of the speeds that he was going), he would eventually relent and decide, albeit reluctantly, to teach her everything he knew.

Their entire relationship would be like Peter Parker and Miles Morales' from Into the Spider-verse, in that of a grumpy, unkempt mentor who's secretly proud of his student, and said student who is eager to learn and super respectful of her mentor, but also isn't afraid to poke fun at him from time to time.

But all of this is just my idea. What do you all think?
