Ant-Man from The Avengers: United They Stand
This 5-inch Ant-Man figure from Toy Biz was based on the animated series from the late 90s. The figure's arms and legs pull out to make it larger. The set comes with a helmet and a Mini Jet that the figure wears as a backpack. The magnet on Ant-Man's arm can open the wings and cockpit, revealing a tiny 1-inch Ant Man figure.
This figure is new in a great package.
