The Priestess (Boss Character) 
The Priestess is the leader of a cult devoted to merging humans with animal species to create "enhanced" beings, She wears ornate ceremonial robes, a symbolic headpiece marking her authority, and wields a large scepter.
Phase 2: Once weakened, she loses her headpiece, revealing a horrifying face and long, floating hair. Her scepter breaks, and her wings rot and deform into grotesque masses of flesh and animal parts. 
One wing wraps around her body as a living shield, while the other fuses with her arm and broken scepter to form a massive, shifting blade made of flesh and beasts. 
She becomes a brutal close-combat creature, overwhelmed by her own power.
