Reformatted Ch. 1
Disclaimer: I do not own Harry Potter or Transformers
Cybertron was dead and Primus knew it. Despite his attempts at peace, his children's war had all but destroyed his main body and it was time to move on.
Of course, Primus would leave a fragment of his spark in Cybertron's core in the event that his children revived his main body. Most of himself, not counting the semi-sentient part of himself in the Allspark, will move on and be reformatted. With one last silent farewell, Primus faded into the afterlife.
A long, long time in the future on a world far, far away a baby was born bearing a recycled soul. A certain black-haired, emerald-eyed boy on July 31, 1980. Unbeknownst to his new parents, Harry's eyes glowed blue once before becoming green once more.
One year later...
Voldemort watched with vague sick glee as Lily Potter fell, already dead by his hand. With that matter out of the way, he turned his attention to the sole Potter living and his reason to be out tonight. One vaguely defined child of prophecy, Harry Potter.
The baby was surprisingly quiet considering his mother was just murdered in front of him. Having Double checked the preparations for a new horcrux, Voldemort readied his wand for what would be, in his mind, the kill that would define the end of threats to him excluding Dumbledore.
With one glee filled "Avada Kedavra" a foreboding green light rocketed towards the baby with every intention of killing its target.
Or it would have, if not for one occurrence, Harry's eyes glowed blue. But not a blue found naturally on Earth but the distinct blue of energon or of a spark.
It must be noted that reincarnation affects only the memories of the soul and for some, like the god and creator of Cynertronians, it meant very little for stopping their awesome power. Normally Harry's magic would have reacted but his subconscious realized that it would be ineffective.
With a wave of his blue, glowing baby hand, Harry reflected the curse back to Voldemort and the power Harry had awoken went back to sleep until its master was either ready for it or its master was in danger.
From there, events followed through almost like many other similar universes. Eventually it all lead to Harry being found on his Aunt's doorstep in the morning after a November night with only a vaguely phrased letter to explain his presence.
The only notable consequence was an echo of Primus' and now Harry's power gaining the attention of a dying race, many light years away, towards Earth. Those on Earth though, assumed the humans were experimenting with the Allspark.
