Intent on taking over the planet and stopping Godzilla should he interfere, aliens build a mechanical version of the King of the Monsters. Realizing Mechagodzilla may be too strong to take on alone, humanity summons the legendary King Caesar to assist Godzilla in battle. This beastly box of behemoths can barely contain Godzilla, Mechagodzilla, and King Caesar, all with interchangeable head portraits and their own unique accessories! Godzilla comes with two interchangeable head portraits and a heat ray FX; Mechagodzilla comes with two interchangeable head portraits, two Space Beam FX that attach to his open-mouth head portrait, one Cross Attack Beam FX that attaches to his chest, and two interchangeable Finger Missile hands; and King Caesar comes with two interchangeable head portraits and one Prism Eye FX.
