Lily had run upstairs with her twins when James had told her to run. She had barely reached the landing when Lucius Malfoy came running up the stairs.
"No not my babies. Please not my babies." Lily sobbed when Lucius pointed his wand towards her.
"No the Master wants to kill them himself. I get the pleasure of killing you myself though you filthy mudblood. Reducto!" Lucius said smiling before seeing his lord.
Harry a three year old and the oldest Potter child hearing the yelling came out of his room.
"Oh Master it is the third Potter child. Can I kill one at least?" Lucius begged of his master.
"Get out of the house Malfoy. I want the pleasure myself." Voldemort ordered of his most faithful servant.
During this time Harry had moved over to his crying little brother and sister. Turning to the children Voldemort smirked "How could one of these children destroy me? I am the most powerful wizard alive it is not possible that a three year old or an infant could beat me."
Having finally calmed his siblings Harry turned to the dark lord. "You will no hurt my siblings."
Voldemort laughed at the young child standing over his siblings. "I like your spunk kid. Sadly I cannot allow you to live. You would be an amazing apprentice. AVADA KADAVRA!" As soon as the words left his lips Voldemort knew something was wrong. As soon as it left him so did a part of his soul. As soon as it hit the young child it somehow was absorbed into him.
"AVADA KADAVRA!" Voldemort screamed again. This time the spell hit the child but did not release from the wand in fact it mostly drained Voldemort of his magical strength. As his body was just held together by his magic it fell apart resulting in an explosion.
Seeing the collapse of the building and his body falling apart Voldemort decided that there was no time better then now to flee the building. As Voldemort's soul piece fled a large piece of wood hit James Jr. leaving a scar in the shape of a serpent on his neck. The soul fragment that had broken off before Voldemort's demise flew into the body of the destroyer.
Suddenly a pop broke the silence and an old man appeared. This old man was named Albus Dumbledore. Looking over the three children Albus determined that James Jr. was the Boy-Who-Lived while Britney who was sleeping and unharmed and Harry who was sitting up with wide eyes could not have beaten the dark lord.
After having decided this Albus wrote a letter to the Dursley's explaining what had occurred. For extra security of the Boy-Who-Lived he added a compulsion charm that they would be kind to James and keep him happy.
