What Izuku Midoriya didn't receive One for All? What if he received a quirk that made him act like a different creepypasta? They wouldn't take control of his body. He would just act like them depending on his eye color.

Crystal blue - Jeff the Killer
Weapon: Knife
Personality: An angry, emo boi who rarely is calm

Crimson red/Forest green - Sully/Liu
Weapon: Also a knife
Personality: Liu - A calm, respectful boy Sully - a crazy, blood thirsty maniac who can make his opponent snap

Fully white/Static - Slenderman
Weapon: Slenderman's tendrils
Personality: Creepy

Chesnutt brown - Ticci Toby
Weapons: Two hatchets. One old, one new
Personality: A playful, insane boy

Pure red - BEN Drowned
Weapon: Electronic devices
Personality: A usually chill guy

Dark brown - Masky
Weapons: Pocket knife and pistol
Personality: A very serious person

Amber-green - Hoodie
Weapon: Pistol
Personality: Quiet

Dull green - Sally
Weapon: Tea parties
Personality: Acts innocent to his victims (in this case, villains), is really a demon that will paralyze you

Emerald green - Izuku Midoriya
Weapon: His intellect
Personality: A sweet, innocent cinnamon roll who is very smart and is always trying to be positive

I imagine he would still be a hero and wouldn't go through ten months of training. He would sometimes lose control of his quirk but soon learns how to control it. Bakugo would still be an bully/explosive pomeranian. I'll leave what would happen if Izuku had this quirk for you guys. Also, his weapons magically appear depending on his personality.

Luna out!
