The Rebirth (1) - S4.E1

While much has changed and there has been a peaceful lull lately, the Decepticons are happy to get back to basics. Soon, Autobot City is a mess and the Plasma Energy Chamber key is stolen. The fight moves to Cybertron and in front of the soon activated the Plasma Energy Chamber, no less. An unexpected reaction from it, though, leaves a number of Transformers on both sides (plus Spike and Daniel) on Nebulos. Greater fighting awaits there, as machine-hating Nebulons seek to overthrow the evil Lord Zarak and the Hive. Getting back home is, of course, on hold for the recent arrivals to Nebulos. However, the Hive appears unstoppable and only something truly radical may work against them.
