Bobblehead. This summer the heroes of the Marvel Universe join forces in the long-awaited Avengers movie from director Joss Whedon. NECA brings the characters to life with a series of Avengers Movie Head Knockers, recreating the heroes in painstaking, movie-accurate detail. All four head knockers stand on Avengers-logo bases, are made in consistent scale, and can be displayed together. Choose from Captain America, Iron Man, Thor, and the Hulk.
