Voltage in Silence (MHA Fem Todoroki x Experimented Male Astalos Reader)

Y/n Raizekusu was born with wings too sharp for the world to hold.
From his first cries, lightning bled from his veins, crackling neon green sparks that branded him a monster. Before he could walk, he was feared. At six, a panicked surge of power left bystanders dead. Society didn't see a child. They saw a weapon.
He and his mother, Dragoon Hero Ryuko Tatsuma, fled into hiding. But safety was an illusion. Y/n was stolen by Helix Fang, a rogue faction backed by corrupt officials. For two years, he was tortured, dissected, and forced to transform until pain became the only thing he remembered.
When Ryuko finally found him, her son was no longer a boy, just a silent, fractured shell with lightning in his blood and trauma in his bones. Even now, at 17, he flinches at touch, stumbles over words, and wakes up gasping in the dark.
His Quirk, Electric Wyvern, has become a terrifying force. In combat, he's brutal, calculating, more storm than student. U.A. offers him a place, but he doesn't dream of heroism. He dreams of protecting the broken. Avenging the forgotten. Becoming the hero he never had.
But inside him still lives the beast Helix Fang created, the Astalos. And if it breaks free again... they won't cage him. They'll end him. Y/n walks the line between monster and man.
And he knows: monsters don't get second chances.
