All For One was defeated by Bakugou though he wasn't killed, so when everyone was defeated and he was left as a baby, you got stuck to take care of him until they found a cure to turn him back into an adult! Yippie that was fun, or so you thought.
Now here you sat in your apartment as All For One was greedily drinking milk from a bottle because you be damned if you let him be breast fed! Though you wondered what was going through his head since you know he could think, he just couldn't talk anymore.
"This is humiliating."
All For One thought to himself, though it was the only way he could currently survive, luckily he still had a bit of his powers, but he wasn't gonna use them against you, at least not yet.
"Though, I suppose I could use this to my advantage."
He continued to drink greedily, since he had always and forever will be greedy no matter the costs.
