This animation series tells more about the adventures we will have during the Great Cybertronian War, which left many disasters. After that war, the Autobots and Decepticons landed on the ground again. Millions of years later, the geological activity begins with a different activity, reviving the warring factions. Decepticons are trying to strip the Earth of its vast resources of energy, while the Autobots try to protect the inhabitants of the earth from this painful fate.
Even though the Transformers franchise has now moved way beyond the products, the series holds up well. Yes, the animation is very clunky by today's standards, but the transformation effect never gets old.
