Transformers Galaxy Force EP41 - The Descent of Master Galvatron

The Autobots search all over the abandoned cities for the un-erased data on the Cyber Planet Key. Megatron, angered and humiliated after his fight with Metroplex, puts up all his rage by turning into a ghostly form and heads down through the planet's crust. He then finds the Giant Planet Key and tries to take it. Unsuccessful, he emerges, with a black aura surrounding him. With his new power, he easily defeats all the Autobots one by one with no effort. As his aura disappears, he renames himself Galvatron. However, he is defeated by Optimus (by using Metroplex's axe and activating Giant Planet's Cyber Key). With the data recovered by Coby and Lori, the Autobots scout the planet in Ogygia and find Atlantis in a newly created fissure in one of Giant Planet's abandoned cities.
