Build the ultimate battlefield with Siege figures. Siege plunges fans into the epic fight to survive on the final day of the Autobot and Decepticon battle to control Cybertron. The Decepticon resistance army and the Autobot counter-resistance fighters gear up with the C.O.M.B.A.T. (Cybertronian Omnifuctional Modular Battlefield Assault Tech) System, the universe's most advanced modular weaponry -- including the Decepticon menace Apeface. The Voyager-class triple-changer comes with SA Sonic Boom Blaster, EM Electro Shield, and little buddy Titan Master Spasma. Figure features multiple C.O.M.B.A.T. System weapon ports to attach weapons, enabling custom configurations in bot and vehicle modes.
