Hadoryu
A fireball so powerful it'll rip your guts out and use them as laces for its own shoes. You'll be so full of pain you'll cry like a baby who lost their cookie.
I used Hadoryu on my math teacher and now he's a smoldering calculator.
My friend tried Hadoryu and his hands swelled up like balloons.
My mom used Hadoryu on my dad and now they're both stuck in a black hole.
