Transformers: Armada Season 3 Episode 13 - Crisis Episode Title:Crisis.Episode Description:In this episode, Megatron forms the Hydra Cannon, made up of the Star Saber, Skyboom Shield and the Requiem Blaster. He plans to use it to destroy the Autobot HQ on Earth. Instead, it was used to nearly destroy the Earth's orbit! Optimus Prime and Jetfire both set out to disengage the Hydra Cannon and free the Mini-Cons. Megatron wasn't about to let Optimus and Jetfire destroy his cannon, therefore he sent Demolisher, Cyclonus, Wheeljack, and Tidalwave to destroy them, and to test his loyalty, sent Starscream. Thrust stayed behind to charge up the Hydra Cannon. Optimus appeared to be winning, so, Megatron took him on, while Jetfire was pinned down by demolisher, Wheeljack and Cyclonus. Megatron pushed Optimus' face towards Earth to watch it be destroyed, but Optimus zapped him with the Leaders Matrix. Thrust fired the Hydra cannon, but somehow, Optimus manages to escape and jump in front of the cannon. Optimus uses his Matrix to absorb the blast, but sacrifices himself in the process. All that is left is Optimus' matrix! Jetfire went to look for the remains of his fallen leader, but all that was found was some space dust! Even though he had finally defeated his enemy, Megatron cried. Jetfire swore he would never forget his leader.
