Over a million years ago, Cybertron was destroyed by war and the All Spark was launched into space, with Megatron in pursuit. Its course was altered to Earth. In 1897, on an Arctic expedition, Captain Archibald Witwicky falls through the ice and discovers a frozen Megatron. When the captain chips at the ice covering Megatron's face, light from Megatron's eyes blind Witwicky, but burn a map of the All Spark into his glasses.
