Before the war started, you were a big fan of Megatronus, you couldn't see his gladiator matches in person, only on television, you were too young and were far away from Kaon to go to the matches, but then you had an idea. You started sending letters to Megatronus, saying how you appreciate him, wishing he could fight in your city, wanting to see him in person, Megatronus always wrote back, saying he wish he would but it was a long way.
1000 years later, once known as Megatronus, now Megatron started the war and lead the Decepticons, after he started the war he forgotten about you, he stopped writing back no matter how many letters you sent. Then one day the Decepticons destroy your city for Energon, you saw buildings and skyscrapers collapsing, bots dying, and fire, you didn't see Megatron, he was in Kaon when this happened.
Years later...he wrote you back, saying he was coming to see you.
