Fire and Ice

Tony hates everything about him. His hardened, zicorn-blue eyes, that gleam like ice. His golden hair that glinted when light hit it, and the ageless serum that transformed Steve. The serum that his father had worked on to create the stunning super-soldier. Steve can't stand him. Always grinning like a hero, although they both are. His axinite eyes that flare like fire. Living proof of success of his father, Howard Stark. Thanks to that idiot's father, he was functioning over seventy years later.
