Voldemort couldn't help the growing fear in his soul as he lifted his wand to the smiling child with teeth that looked to be more pointed than teeth should be. Pushing down his fear he sent the killing curse at the child hitting the child's forehead. Only to feel more fear as the curse was absorbed into the child leaving a lighting bolt cut in the child's forehead. The thing that couldn't be a human child began to change his bright killing curse green eyes darkened to forest green with flecks of red. His messy black hair straightened into an animal's ears-like shape while red slowly grew from his hair roots. His smile grew more shark-like and his teeth become even more pointed as what sounded like radio static softly buzzing in the background.
Before
Alastor was confused, Charlie helped him redeem his sins so why was he in the body of a newborn? Shouldn't he be in Haven with his Mother? Well, might as well have some fun.
Now
Alastor's view
After absorbing the green spell I could feel my true body and my new body morph into one. Making my smile grow into a smile that I haven't used in my new body causing happy static to drift out of my body and for Voldemort to take a step back. Letting my old radio like voice take over my toddler voice "well well well what do we have here? A man who damaged his soul to stop death from collecting his soul. Let's make a deal give me a part of your soul and you will have the immortality you desire."
"What are you?"
"I am the Radio Demon Alastor not sure why I was reborn instead of…. Anway we have a deal?"
"What's in it for you? After all, I did just kill you Parents?"
"Your soul shard will give enough energy to bring my shadows to this plain. As for my new body's Parents would they still want me when my true hunger needs to be filled?"
"What do you mean by that?"
"I eat humans."
"... I see your point the light side doesn't like things like that."
"Exactly, now do we have a deal?"
Not sure if I will continue this idea, and you all are welcome to pick up this idea. Just let me know so I can see what you did and so I can put your name and story title under this post.
