I know this has been done before, but it seemed kinda vague, like ALL the Autobots vs. All the sentinels.(No offense intended to anyone) I just think that was incredibly unfair considering the Autobots have Omega Supreme, Metroplex, Skyfire, etc. Here I want to create a more evenly matched battle.
The war between the Autobots and Decepticons is in a cease-fire. The Decepticons are spread through the universe, while the Autobots have control of Cybertron. Earth has been watching the events of the War, and the governments of Earth fear the Cybertronians. They agree to create an army to combat the Cybertronians, adapting the Sentinels to attack Cybernetic life forms. 250 Sentinels are sent to Cybertron as a test run. An Autobot scout sees the Sentinels approaching and warns Optimus Prime. Most of the Autobots are recovering from serious injuries sustained in the war. Optimus orders an evacuation of Cybertron. Optimus is determined to stay behind until everyone else has left, but some of his bravest soldiers refuse to leave without him. This group of five Autobots stays behind to defend Cybertron.
250 standard Sentinels, attack only Cybernetic organisms. Led by Master Mold.
Five Autobots: Optimus Prime, Bumblebee, Ratchet, Ironhide, Ultra Magnus. Standard G1 Autobots. Standard weapons, both ranged and melee.
20 minutes prep time for Autobots.
