Transformers Galaxy Force EP27 - The Countdown to the Doom of the Universe

With the help of Scourge, Megatron and the Decepticons are finally freed from captivity. They decide to head to Earth, and Scourge joins them. Meanwhile, Starscream places the Earth Planet Key in the Omega Lock, and a space bridge is formed, revealing the black hole to Earth and the entire universe. A transmission is received by the Autobots, and is deciphered by Red Alert and Vector Prime. The message says to bring the Planet Keys and Omega Lock to Cybertron, but does not indicate what will happen. However, the Decepticons appear at Niagara Falls, and the Autobots rush to challenge them. In the battle, Megatron is challenged by Hot Shot, Red Alert, and Scattershot. In the process, Megatron gains a new weapon from Earth's Cyber Planet Key - a gatling gun! Megatron promptly uses his new weapon to seemingly wipe out the three Autobots.
