Nomu

You were working for the League of Villains, manufacturing Nomus on AFO's orders, under their control. You were in your lab working on a Nomu that could match All Might's power, your greatest creation slowly bearing fruit. After months of work, the Nomu was finally ready. It was encased in a liquid-filled capsule to keep its body healthy and hydrated. Slowly, the Nomu began to show signs of life, opening its monstrous eyes and looking at you, its creator.
