UPDATE ABOUT CRYSTAL AGAIN (god.)

Crystal was actually delivered by a angel that looks like Amy Rose. In the movie infomation, Bernadette gave birth to Crystal, who is the future princess of the heavens, but in the series (Sharp), she was born in the heavens and Angel Amy (Crystal's mother in the heavens, while Angel Sonic is her father) delivers Crystal to Sonic, and it was brother/sister relationship at first sight. But when Cream discovered Crystal, Cream says that Crystal is "crap", and Crystal casts her first spell, which is a invisible Angel Amy pulling Cream's ears. One night when the moon was a strange color, Angel Amy brought Crystal to Sonic's house. No one knows where she came from. Immediately adopted by Sonic's family, she completely changed their lives - but no one's complaining. Everyone except Cream loves Crystal, with all her good and bad sides. Crystal had to return to the heavens when Sonic revived her with a special flower when he was in his 1000 year sleep, but Crystal's love for Sonic, Tails, Knuckles and Amy reached the heavens, and Crystal had to return. One month later, Crystal runs away to Sonic's house and suprises her brother. I'll give you more info if i have more time.
