Transformers: Nitrobots

During the first Cybertronian War the Decepticons held a major advantage over the Autobots. They're aggressive nature and lust for destruction making them much more capable fighters, allowing them to win control of the planet easily. During this time Alpha Trion and a group of Autobot Elders journeyed to Vector Sigma to have the great computer create a group of Autobots to combat the Decepticons. Using the Key, Alpha Trion succeeded in creating the Nitrobots. Five Autobots with superior fighting skills. The Nitrobot leader, Land Raider, promised that the Nitrobots would not stop until the Decepticons where defeated. Alpha Trion, took the Nitrobots back to his workshop, where an injured young Autobot was being repaired and refitted. This Autobot was to be the new leader of the Autobots, Optimus Prime. Land Raider was unsure of this, and claimed he should be the leader of the Autobots. But Alpha Trion convinced him that Prime should lead, because he was not as hostile as the Nitrobots and the other Autobots would follow him more easily. Land Raider agreed to serve Optimus Prime and when he awoke, Land Raider and the other Nitrobots swore their loyalty to him and the Autobot cause.
So the Nitrobots, led by Optimus Prime, fought back against the Decepticons, and at first won many victories. More and more Autobots flocked to the banner of Optimus Prime and in short order the war was at a stalemate. This lasted for millennia, and as the war dragged on, so the planets energy reserves where depleted to the point of being empty. In a desperate attempt to find a new source of energy Optimus Prime ordered the Nitrobots and a small team of Autobots to leave Cybertron and seek out a new source of energy.
And so it was that Land Raider left his leader and friend Optimus Prime behind and began the search for energy.
