Build the ultimate battlefield with Transformers War for Cybertron 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 universe's most advanced modular weaponry, including the weapon modes of combined Micromaster figures -- sentient bots that combine to form weapons. The Smashdown toy converts from beast mode to Airquake Hammerclaw weapon mode in 6 easy steps. Use the weapon mode to equip other Siege figures (sold separately) with larger mission loadouts and use the included Fire Blasts accessory to look like the impact of a hammer hitting its target.
