Jotaro Kujo (Undertale)

It's a normal day at DIO's mansion, and it's somehow quiet. Oh right, your father isn't home today, and you're alone. But suddenly, a roar is heard outside, and the most unwelcome guest in your house appears before you: Jotaro. He wanted to kill your father for killing his friends (Kakyoin, Polnareff, etc.) and his mother in Japan, who was dying. But seeing only you, he decided to take care of you, saying, " It's a beautiful day."
The sun is shining, the birds are singing!
On days like these, kids like you…
Must die!
Turn around, I would never
I did not break the word that I gave you.
When you cross the line,
You will burn in hell!
People like you don't play by the rules,
But fools don't defeat people like me.
So let's start having fun,
Come on, you dirty fratricide!
Mercy - down with us! We will fight!
Attack, try to get to me!
I guess you're tired of trying,
Die a hundred times and be reborn.
This courtroom has become your grave.
You will never leave him,
You are forever bound by this fight,
Because you are a worthless warrior.
You are made of love!
Here we go again... Here we go again...
Never mind, try to beat me again.
I mock you, but you crawl back into battle. All the sins you've committed haunt you.
Mercy - down with us! We will fight!
Attack, try to get to me!
And don't even try to ask for mercy.

• My brother didn’t wait for it from you!
  You divided all my friends by zero,
  I am here so that you can share their pain!
  I am their mercy.
  I am their vengeance.
  I am their EMBODIMENT.
  You are made of love!
  But I am stronger than you!
  From this moment on, your fight with the Stands begins, not for life, but for death. Who will win?
