(Should I change her color to light yellow or something or keep black?) Grim Dark is known as the reaper pony. Even do thats her power she auctually adds more life instead of taking if they were good. Basicly a rebirth but you can choose any age you want to be back in. But if the pony evil she takes there life and make them start all over as a kid. In love with Blazing Heart she tries her best to get him to notice her. Her cutie mark is a scy.th it represent life, de.ath, and rebirth.
