5. Transformers: The Game
Ok, I admit, this one refers to the Deceptecon portion of the game. Play as an Autobot, and it’s flowers and puppies and pretty girls dancing in fields* when Optimus Prime defeats Megatron and saves the earth. However, the reverse happens in the Deceptecon campaign. Here Megatron slays Optimus Prime and takes the All Spark for himself.
The All Spark, once activated, turns every electronic device on earth into a Deceptecon. Megatron can then use these newly formed minions to enforce his will. His will, in this instance, is to wipe out humanity and leave earth a dead, barren planet. No puppies for you.
*I assume this is what happens. Transformers: The Game is ass, so I haven't played it.
