Build the ultimate battlefield with Transformers War for Cybertron: Siege toy 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.

The WFC-S11 Optimus Prime figure features story-inspired battle-worn deco and is equipped with a W-50 Dual-Mech Energon Strikeshield weapon accessory with converting axe and shield modes and a W-M3 RF Ion Blaster accessory. The 2 weapon accessories mod-lock together to form the larger Sentrystrike Ultra-Blaster. Multiple C.O.M.B.A.T. System weapons ports in bot and vehicle modes allow fans to attach weapons to figure in custom weapon configurations.
