YMMV / Transformers/Back to the Future

• Complete Monster: Alternate Timeline Megatron is as per usual a brutal tyrant. Due to the manipulations of a time-traveling Rumble, Megatron and all the other Decepticons were awakened prematurely. Megatron would kill off Optimus Prime, and without him to stand in his way, Megatron quickly conquered the world, killing most of the Autobots and forcing the rest underground. Megatron would also murder Rumble for seemingly no reason and used Biff Tannen to enslave all of Hill Valley, where the population would be forced to mine for energon. Megatron would also murder them whenever they failed to meet his quotas, as well as killing anyone who opposed him. By 2015 Megatron's sheer level of cruelty eventually got so bad that it caused Gigawatt to turn on him. Megatron attacked him, intending to kill him, but Gigawatt was able to escape just in time.
