The X-Men universe is a complex and compelling world where humans coexist with mutants, individuals born with extraordinary abilities. At its core, it's a story of prejudice, acceptance, and the struggle for equality.

• Mutants and Humans: The central conflict revolves around the discrimination faced by mutants, often referred to as "mutants" or "Homo sapiens superior," by the human population.
• The X-Men: A team of mutant superheroes led by Professor Charles Xavier, who strive to protect both mutants and humans from threats. They embody hope, tolerance, and the belief in a world where humans and mutants can coexist peacefully.

The X-Men universe has expanded across comics, movies, and television, captivating audiences with its blend of action, drama, and thought-provoking storytelling.
