Here's why he's considered their arch-nemesis:
* Shared History: Magneto and Professor Xavier were once friends, even roommates, who both witnessed the horrors of the Holocaust. They both had strong mutant powers, but their paths diverged due to their differing views on how to deal with the threat of human prejudice against mutants.
* Opposing Ideologies: Xavier believes in peaceful coexistence and integration of mutants into human society. Magneto believes in mutant supremacy and wants to see humans subjugated.
* Frequent Conflicts: The X-Men and Magneto have clashed countless times throughout their history, often resulting in devastating battles.
* Personal Connection: The personal bond between Xavier and Magneto adds another layer of complexity and tragedy to their rivalry.
While Magneto is the most well-known, other prominent X-Men villains include:
* Apocalypse: A powerful immortal mutant seeking to create a new world order under his rule.
* Sabretooth: A brutal and savage mutant who has a long-standing rivalry with Wolverine.
* The Juggernaut: A powerful, unstoppable force fueled by his own rage and anger.
* Mr. Sinister: A brilliant but twisted geneticist obsessed with mutants and manipulating them for his own ends.
The X-Men have faced a wide variety of threats over the years, and their adversaries have evolved along with them. However, Magneto remains their most enduring and iconic nemesis, embodying the ongoing struggle for acceptance and equality between humans and mutants.
