Optimus Prime is the leader of the good faction of Transformers known as Autobots. He is leading the battle against Autobot’s sworn enemy, the Decepticons, for the protection of life on Earth, Cybertron and all parts of the universe.
Optimus was once known as Orion Pax, a simple dock worker during the Golden Age of Cybertrons. He was destroyed by Megatron when the warehouse Optimus that he was protecting was assaulted by Megatron and the other Decepticons thus killing Optimus. He was later reconstructed to be Optimus Prime by the Alpha Trion who gave him the Autobot Matrix of Leadership which is placed on his chest and is a symbol carried by all Autobot leaders.
He is a gallant, valiant and compassionate Autobot. He is an adamant leader and would avoid insincerity on his command as much as possible. Optimus is also a direct, wise and essentially cheerful battlefield general.
His powers include short-range optic attacks, holographic map projections, a palm-mounted, triangle shaped repulsor projector and a distributable hydro-foils which allows him and the other Autobots flexibility in undersea environments.
His transforming vehicle is a cab over semi-truck. The truck’s cab transforms into Optimus himself while the truck’s trailer is transformed into Combat Deck and launches Optimus’ Roller.
When Cybertron fell from its orbit, the Autobots led by Optimus boarded an ark to destroy the asteroid. However after reaching success in their mission they were consequently attacked by the Decepticons and Optimus decided to crash their Autobot ship, Ark, into pre-historic Earth.
Optimus is in constant fight with Megatron, the leader of the other faction of Transformers and in some cases teaming up with him when they are battling a common enemy. He is usually on the front line battling Decepticons and defending the Earth.
When the Decepticons had taken control of the Cybertrons and they planned to destroy the Autobot city on Earth, Optimus Prime bravely defended the planet and was fatally injured. Despite Perceptor’s efforts of reviving him, Optimus died. He was later on reconstructed as Rodius Prime and thus leading again the Autobots in a continuous war against Decepticons.
