Silent Death

Defeat

...

"I AM HERE!!" all might cheered.
Midoriya's eyes widened as his quirk deactivated.

All might punched the sludge monster, blasting it right off of Bakugo who was finally released from its grasps.

He landed on the ground, coughing.

"All might!?" The teens said in dismay.

"Ha!
Ha!
Ha!
Looks like you 2 got caught in a predicament, but no worries because I am here!" All might smiled.

"Can you sign-"

"Already signed!
Off I go"

"Wait there's something I need to ask!" Midoriya shouted.

"No time!"

Midoriya jumped and grappled onto all Might's leg as he took off, surprising even Bakugo.

"What the heck Deku!" He shouted as he disappeared with all might.

"Kid, kid!
You cant just grab onto pro heroes" all might said in the air.

"I really need to ask you a question, please" he begged.

"I don't have time, you need to let go"

"I'll DIE?!"

All might sighed as he landed on a building.

"I'm sorry for bothering you...
It's just-"
Midoriya was cut off when a poof went off near all might and...

Instead of a buff muscular man, a practical Skelton with blond hair appeared before him.

"You're not all might!?" Midoriya screamed in dismay.

"Sh...
It looks like my secret is out.

Kid.
You cannot tell anyone about this form...
Do you understand...?"

Midoriya slowly nodded his head.

"Okay...

Now what was your question"

"Can someone like me...
Become a hero...

Even with a quirk like mine...?" He asked.
Midoriya's stomach churned as he began to nervously sweat.

"Well?
What's your quirk?"

Midoriya gulped hard, "...i-its called reaper...

I...

I can steal someone's life from them...
I can do it in small amounts and make them grow older...

I can also take their energy and convert it into attacks...

But the downside is
Whenever I use it I lose a piece of my sanity..." He explained.

All Might's eyes widened as he stared at Midoriya in slight fear.
"A quirk like that with such a downfall can easily lead to him becoming a villain...
He'd be unstoppable, I can't allow him to become a hero if that's the downfall...
He'll be evil before he can even reach the ranks...
This'll hurt him but it's for the best..."

Midoriya's heart was practically beating out of his chest.

"I'm sorry kid...
A quirk like that is strong
And if it didn't have such a bad down side you would've been good.

But...

It's too risky, if using a quirk like that making you go insane it's better not to use it at all.
I would hate for you to become a villain because it doesn't seem like you're the type to do that.
