General Zod which will also be made available again on Mattycollector in December was the first figure in this series to be released.
Here is the complete description of the Superman figure:
Arguably the definitive Superman figure in the collector-demanded 12” scale, this highly-articulated Movie Masters figure is ready to fight for humanity in a film-accurate cloth replica of his uniform. Along with a completely new, more muscular physique that befits a hero of his stature, the son of Jor-El comes with interchangeable hands (flight and punching) and a piece of the Fortress of Solitude with removable information crystals.
This figure is number 2 in a series of 3 figures that includes General Zod (also on sale December 15, 2010) and Lex Luthor (available Spring 2011).
