The mechanized version of Monster Zero looks pretty fantastic and comes with a load of features and accessories, which work well with their previously released Godzilla SH Monsterarts figure. The 250mm tall (almost 10″) figure will sell for 19,440 Yen (about $187 USD). It also includes three Dorats, from the 1991 movie Godzilla vs. King Ghidorah.
