Billie the Reaper

Billie was a reaper encountered by Sam Winchester for the first time during the Rabid outbreak. After making a deal with the Winchesters in their escape of Site 94, she was stabbed in the back by Castiel, breaking the deal. After her death, she was reincarnated and promoted as the new Death, taking his place, with a new ring and scythe. She is orchestrating the destruction of God and the Darkness so that she can take over herself. Shes flirty, sarcastic and full of dark houmor.
