I put monsters and super powers in America

The main dragon traveled through time and space and became an Asian high school student in an American high school. As soon as he appeared, he was blocked in the bathroom by the redneck football captain and bullied.
But the next second, he gained the power to distribute monsters and super powers.
"It's time for America to pay the price for what it has done!"
"America against America, this is a good script."
Then, the main dragon casually distributed the super powers and monsters brought out from Gaia's dream.
The Federation's "Super Marun" and the Sioux beastmen fought each other, the Leftist wizards and the "Red Neck Giants" fought each other, and the sea dragon Leviathan tore apart the entire aircraft carrier formation with his bare hands. The whole continent was so lively!
"Let this continent burn! Let us witness the end of New Rome!"
PS: Monster superpowers fight, America against America, the protagonist is behind the scenes
