"Curse you and your whole kingdom!"
Dark Petal is created out of Princess Petal's past. Her past self casted a curse which created a new life form, a.k.a. Dark Petal. Dark Petal's goal is to consume the whole kingdom her parents created.
She can summon fire and shadows. Just like Dark Metal.
Dark Petal looks the same as Petal did when she casted the curse, but instead of green she wears black and she's got red eyes. She's got a black cap and a white t-shirt with a black tie, a black skirt and black sneakers with white socks. She's also got blonde hair.
