Transformers Galaxy Force EP3 - Protect the Secret Base!

The episode begins with Coby, Lori, and Bud having chosen a mountainside for the Autobots' base. Lori reveals that her dad owns the land and was going to use it for house construction, but the market went soft, so the Autobots build their base there. Bud is amazed that the secret base is a secret, but he suggests they build a takeoff tower for Jetfire and Vector Prime. Meanwhile Coby helps build the main computer system, and Lori customizes the base with items for the kids. Out in space, Megatron decides he wants to return to Earth and find out what the Autobots are doing. Starscream says it's a waste of time, but Megatron insists Starscream join him. Back on Earth the Autobots activate their system just in time to detect Megatron and Starscream approaching the earth. Optimus, Hotshot, Vector Prime, and Jetfire head out to intercept the two Decepticons while Overhaul, Landmine, and the kids apply stealth coating to conceal the base. As the Autobots engage the Decepticons in battle, Starscream hits Jetfire, so Vector Prime decides to take on Megatron one on one. He fights him hoping to recover the map, but Megatron refuses. Hotshot transforms and shoots up at Starscream, but Starscream realizes they are being misled, informs Megatron, and the two Decepticons fly past. At the base, Scattershot checks the stealth coating progress and informs everyone that the Decepticons have broken through. Sector D is the only sector left uncoated, so Overhaul rushes over to finish it, but Scattershot fears it'll be too late. Outside Megatron is approaching the base when Vector Prime transports in front of him, cutting him off. Megatron transforms and begins to fight, so Vector Prime activates his Cyber Key and uses his tachyon shield. Vector Prime pushes Megatron back, and while Starscream is distracted, Hot Shot transforms and shoots him down. Seeing Megatron stunned, Optimus transforms and goes into Super Mode. He shoots Megatron, damaging the Decpticon leader, so Megatron calls for a swift retreat. At the base, Overhaul finishes the stealth coating just as the Decepticons retreat and everyone celebrates. Outside, Optimus, Hot Shot, and Jetfire ask Vector Prime what the light was that he used during the fight. Vector Prime informs them that Cyber Keys are a little power from Primus that they can activate, and then he activates their Cyber Key locks so they can access Cyber Key power in the future.
