This is a posable action figure from the Revoltech series.

Magneto from “X-Men” joins the Amazing Yamaguchi figure lineup! He’s about 16.5cm tall, and has joints in an amazing 45 places for superb posability--even his flowing cape is jointed! He has two facial expressions, two interchangeable heads (one with his helmet and one without), two interchangeable hands, and a display stand. Effects parts are also included (they attach with magnets, fittingly enough). Add him to your collection now!
