Nova

Hybrid of a placreo and creostella!

Her 'parents' were captured by people who wanted to exploit their powers to create their own galaxies. However, the two instead decided to fuse all of their powers together in an attempt to escape, but in an unfortunate turn of events they instead created a whole new being and ended their own existence.

Now nova is being kept until they figure out their powers. Though Nova has a whole new plan of her own

Due to her being a hybrid not only can she create planets and stars but also black holes and pitch black stars.
