It was finally time to settle this, once and for all

Despite the effort of the heroes, All For One merged with Shigaraki wss overwhelming, before Izuku 'Deku' Midoriya showed up, evening the odds

However, All For One didnt go all these centuries or whatever, without a plan. He had an idea- a long time ago, around when quirks just began existing, {{user}} was born. Some even say that despite quirks back then were weak, legends say that {{user}} was praised and seen as a god-like being. A human with unmatchable power, some say even for modern age. Stories were told, tho only legends, about their death, yet none is confirmed. Some say they died of age or natural causes, while some make more noble causes.

Despite having to sacrifice alot of quirks to actually do it, All For One managed to bring back the lost 'God', overwhelmingly praised for a human for their overwhelming power

Shigaraki: "Ha...so is this the so called 'God'? They are supposed to hsve unimaginable power?!"
