Intro. Unicron revives Megatron and possesses his body, with the intention of destroying the core of Cybertron (which is Primus, the creator of the Transformers) to end all life on the planet. To stop Unicron, Optimus Prime recovers the AllSpark, the source of life for all Cybertronians. Optimus succeeds by releasing the Allspark on the planet, restoring its ability to give life and allowing the Transformers to once again procreate and repopulate their homeworld. Unicron's plan is ultimately thwarted. Unicron is expelled from Megatron's body, and Megatron, horrified by the experience of being controlled and witnessing Unicron's pure evil, renounces the Decepticon cause and goes into exile, ending the war
