Theoretical Fankid: Chaggie
First up for this little "series" is Charlie and Vaggie.
They have a daughter named Lily Penelope, sometimes affectionately nicknamed "Lil Penny". Named in part for Charlie's mother, and in part for Sir Pentious, both of whom are/were very significant to her parents in some way.
Appearance-wise, she mostly favors Vaggie, being closer to her in height, having a very similar facial structure as well as her eye shape and her skin tone is close to Vaggie's, though a bit lighter from Charlie's gene's influence. She also inherited Vaggie's wings. From Charlie, Lily got her blonde hair, though it's quite a bit lighter, being practically platinum blonde. She also got Charlie's nose and eye color, as well as her hooves and rosy cheeks.
She was conceived through magic - specifically through Lucifer helping them out by using a bit of his own powers to make it so Charlie and Vaggie were able to conceive naturally. Charlie was the one who carried the baby.
In terms of her personality, she leans more towards Charlie, usually being pretty optimistic, though she does have a slightly shorter fuse and is a bit quicker to lose her temper. But she genuinely does care for a lot of people and wants to help as much as she can...even if sometimes the other person doesn't want help. She is also incredibly stubborn.
She is very much doted on my not only her mothers and grandfather, but everyone at the Hotel (with the exception of Alastor) who are all basically family to Lily, with varying degrees of how good or bad of an influence that are on her.
Lily doesn't have any actual powers besides being extremely durable and flight from her wings. It doesn't bother her, though she does sometimes get annoyed at people assuming her lack of powers makes her a pushover.
((Next one of these is going to be for M&M, since they came in second, and then Stolitz, who came in third. After that, I'll probably do another poll))
