From 80stees:

Max Eisenhardt wanted to dominate the human race with the help of mutants. When he was eventually able to pull his magnetic field away from his refrigerator, he re-named himself Magneto and put on an outfit very similar to this X-Men hoodie. This costume hoodie may not give you electromagnetic powers, but with a hood that resembles Magneto’s telepathic-resistant helmet, people will give you the respect a super villain deserves.
