Backstory: Diamond Sparklestone is a unique specimen to behold.
Home in Grand Metropolis, she can do what her heart desires to do.
But there are things that are best unsaid.
Her childhood days is like a mysterious illusion void that she was stuck in limbo for her lifetime, and couldn't get in touch with anyone from the outside world.
It was hard for her.
But one day, she felt a unfamiliar aura when she was in her void.
Its shadow look similar to Silver Sonic, but it was taller, and had a glowing visor for a eye.

Then she gets an interesting idea.
She uses her Shadow Generation powers to create a shadow marionette of that said robot.
She then merges the shadow within her, making her have the ability to use this animated shadow as a means to escape from her prison.

Free, she spends her remaining days living in the city of Grand Metropolis, hoping that her leave won't be long.
She then flies off into the distance, looking forward to start another life, without any interruption.
