It Was Him All Along(Mha x Male reader)

Y/n Agathius Harkness-The Witch Killer. The Arcane Nightmare. He was feared across countries, his name whispered with reverence and terror. But after a fateful clash with the Scarlet Witch, everything changed.

His power? Stripped away.
His identity? Erased from history.
His body? Reduced to that of a fifteen-year-old.

Not even his worst enemies remember him. To the world, he never existed. But Y/n refuses to be forgotten. If the universe won't acknowledge his name, then he'll carve it into the annals of history once more-whether through heroism, sorcery, or sheer, unrelenting chaos.

Let the world remember: He was here first.
