"With the AllSpark gone, we cannot return life to our planet." Maybe I was just tired by the film's end, but that line in Prime's speech at the end of TF1 never really rang a bell in my head. Then it became clear to me in ROTF - the Autobots and Decepticons are seriously screwed here. Without the AllSpark, no restoration of life, and no new life. Shards aren't gonna hold an entire species. "The AllSpark is destroyed, and without it, our race will perish." The Harvesters are completely unacceptable to Prime, so that option is out the window as well. In The Veiled Threat ROTF prequel novel, Ironhide mentions they were able to produce artificial Energon. He also says they could detect real Energon on Earth, but they didn't have time or freedom at the time. They could try to do what they did in G1 - go around turning Earth's resources into Energon. With apparently the bots now common knowledge on Earth, they might have that freedom. So how the hell are they gonna be able to pull through this? Ideas?
