Quick recap
After the blast, several robots get metal bodies, the Transmetals, and faulty stasis pods produce the Fuzors, two-animal hybrids like Silverbolt and Quickstrike. Rhinox restores Optimus's spark, and he comes back with a flight mode. The Predacons figure out the planet is prehistoric Earth and that changing the past could change the future. Megatron attacks the valley where humanity's ancestors live, and Dinobot dies defending them. Ravage, a former Decepticon, arrives to arrest Megatron but switches sides. In the finale, Blackarachnia and Silverbolt find the Ark, the original Transformers' crashed ship. Megatron gets inside, shoots the dormant Optimus Prime and creates a time storm that wipes the Maximals out of existence.
