The Gusoku Myokoh CAS was also available as a mail-in offer; the CAS was cast from resin, as opposed to plastic, and came unpainted. The CAS kit did not come with a Liger Zero Blue Souga but included instructions on how to attach it onto the Zoid. This CAS saw two releases; the first release of the armor, sold as a convention exclusive at C3X in 2005, was limited to 200 units and included a Midori figurine. The second release of the armor, sold through the Tateishi store was limited to 10,000 units, but included a 1/72 scale Midori pilot figure as opposed to the larger scale figurine.
