User blog:Lover of the Muse/All for One & One for All: Origins

At some point in the future I want Izuku Midoriya to be able to commune with or at least access the memories of past One for All holders. It's already been implied that there is some kind of psychic imprinting as the power is passed on from one person to the next.

Ideally at the same time Izuku Midoriya is learning this information, All for One is telling his side of the story to Tomura Shigaraki. For the sake of simplicity I'm going to refer to All for One's younger brother and the original holder of One for All as "Primus" which is latin for "the first".

I don't expect or want that to be his actual name but it was awkward to write "the little brother" or "the first holder' over and over again.

Episode 1: All for One: origins
The first story we learn is the backstory of All for One and Primus. We get to see their childhood and teenage years in an age when superpowers were first emerging. Then we see All for One's rise to power and how his aparrently quirkless younger brother tried to oppose him.

This episode builds up to the moment when All for One gives his brother the stockpiling quirk and we finally learn why that happened. The episode concludes with Primus activating One for All for the first time.

Episode 2:  One for All: origins
Primus uses his newfound power to escape. From there the episode shows us Primus' career as a superhero and his ongoing battle against All for One. (this happened durign a time before 'official heroes' when ever superhero was a vigilante). During their first confrontation All for One tries to take back the quirk but finds he is unable to do so. We learn how Primus figured out he could pass on his quirk. We are introduced to Primus's sucessor.

The episode ends with Primus's death. Either he is killed directly in battle havign already passed on  his quirk, or he escapes mortally wounded and passes on One for All in his dying moments.
