The Invincible Iron Man (Male! Iron Man! Reader x Ruby Rose)
17 parts Complete (Y/N) (L/N), current CEO of (L/N) Enterprises, is a self centered, ego filled teenager, who has started a war against the White Fang and all faunus. At Beacon Academy, he reunites with his childhood friend, Weiss Schnee, and meets her friends, including Ruby Rose.
During a demonstration of his new weapons, (Y/N) is abducted by the White Fang, and forced to create a weapon of mass destruction. Instead, he creates a suit of armor to escape.
The experience traumatizes (Y/N), and makes him learn the error of his ways, turning him into a depressed mess. Ruby, seeing how he has changed, tries to give him something he desperately needs: a friend. In the process, she falls in love with him.
After discovering that his weapons are still being used to kill innocent people, (Y/N) creates a new suit of armor to clean the (L/N) legacy.
