Chapter 1: Child Of The Entity
The Entity flew at the outskirts of its home Space Sector. Its own home planet had five lanterns registered to it; four green and one red. The Entity knew it was time for it to get a host.
It set it's course for a town called Godric's Hollow in the United Kingdom. A woman with ginger hair sat in a pristine garden with tears slowly moving down her face. Lily Potter had suffered from a miscarriage but unbeknownst to her a single cell of the child that was going to be Harry Potter still lingered. The single cell was all that the Entity needed, The cell quickly replicated; Harry Potter was reforming. Once the process was completed the Entity entered the child. If the Entity hadn't bonded with Harry his DNA would have started to rapidly degenerate.
Lily had long since entered her home, this wasn't the first miscarriage that she had. This miscarriage was the one that hurt the most though because her baby had been growing for two months. This was a lot longer than any of her previous miscarriage. She had thought that this time would be different, this morning she had used a pregnancy spell, if she was pregnant blue sparks would issue from her wand while if she wasn't red sparks would fly out. The wand spat out red. Lily grabbed her wand and blue sparks shot out.
James shot smoke rings of various colours out of his wand, Harry tried to grab the smoke as Lily watched from the kitchen. To say Harry had brought joy to their lives was an understatement. She had longed for motherhood but little did she realise was that tonight was the night when her life was going to be tragically cut short. A bang issued as the front door was blown off its hinges. The fieldus charm was broken.
"Lily, he's here! Take Harry and run," screamed James. A unearthly cackle resounded through out the house.
"Avada Kedavra," said the Dark Lord as James Potter fell to the ground.
Lily had pushed all the furniture against to try and stop Lord Voldemort from finishing the job. Furniture was not enough to stop the Dark Lord.
"Move aside, girl," said Lord Voldemort.
"Please, not Harry," she pleaded over and over again. Tom didn't even move his lips as the green light of the killing curse collided with her chest knocking her dead. He raised his wand at the now crying baby.
"Avada Kedavra," he screamed. The green light smashed out Harry and rebounded towards the Dark Lord with red, orange, yellow, blue, indigo and violet light. At that moment Tom Riddle felt pure fear as the light tore his mortal body into pieces. The power of his horcruxes was useless, the white light of life could not kill but could destroy a body. The lights joined together and tore apart the upper floor of the house in Godric's Hollow.
Hours later a man dressed in a trench coat inspected the wreckage. He looked around to see if anyone was watching. Relief fillied him as he transformed back into his natural form with his green skin, red eyes and bald head. J'onn J'onzz used his mind and found the bodies of James and Lily Potter. He placed their bodies next to each other and searched the wreckage for survivors but to no avail. After an hour J'onn flew away to another emergency unaware that a child had been taken from the building earlier that evening by a half giant.
