Warp Cannon

Warp Cannons are massive Cybertronian weapon emplacements.

Transformers: Fall of Cybertron
During the Great War, the Autobots attempted to flee Cybertron on board the Ark, while the Decepticons staged an all-out offensive against them. In this time, three powerful Warp Cannons were deployed to destroy the Autobot vessel and its defenders. Whilst attempting to defend the starship, Optimus Prime awakened Metroplex, who was sent to destroy these Decepticon weapon emplacements. With Metroplex's aid, the first two Warp Cannons were destroyed with ease, but the third weapon managed to heavily damage Metroplex after it had targeted him. Despite being badly damaged, Metroplex managed to survive, and destroyed the last Warp Cannon and Megatron, thus ending the immediate Decepticon threat to the Ark.
