A friendly Autobot named Bus was letting people off at a stop in Shanghai. Among the city was Megatron, looking for the Allspark. He ran up to him and suspected him to be an Autobot-- as he was in his Vehicle form. The bus slowly moved forward and Megatron followed. Megatron asked again for the Allspark. Eventually the autobot released an exhaust-like sigh and transformed. The bus towered 2 feet higher than Megatron. They began to talk.
"Tell me where the Allspark is!" Megatron asked again.
Bus replied, "I do not know."
Megatron was getting angry, so he asked, "You are an autobot," pointing at the symbol on his chest, "What's that!?"
"A symbol." Bus replied calmly.
"Then you know Optimus?" Megatron replied.
A little late for words, Bus mentioned, "A sign of allegiance."
Megatron went on, "Tell me where the Allspark is..."
Bus repeated, "I do not know."
Megatron reached his boiling point, "But you are an Autobot!"
Bus said yes.
"Positive?"
Bus said yes again.
Megatron released his blades and charged at Bus. He leaped over Bus and stabbed him in the back. It wrenched to the side of his spark, and Bus threw him off over his head. Megatron took cover behind some buildings and took on his fusion cannon. He quickly fired it once, but Bus ran out of the way. Bus took some shots at him and missed. Megatron leaped onto the building and launched himself onto Bus. Bus kicked him off at fired at him again. This hit, but Megatron didn't retaliate and stabbed him again into the spark. Though wounded from an earlier power down from the fight, Megatron broke his neck and smashed his face in with his foot.
( Tried to do that as best I could. Get my side in ^^. )
