Were-Banshee

Marlena Gassin may have fell for those blood red eyes once bit not again. She grew out her claws and hovered over her alpha. "Could have just left the pack as it was." She said. He had betrayed their pack ad trying killing all of them just to join ducaliens pack. Only Lena was stronger than him and was going to kill him for killing her animal siblings. With that she slashed him throat and claimed the spot of an alpha along with the powers of a shapeshifter and a banshee. Now all she had to do is find Beacon Hills and warn Scott an his friends of the pack that's coming while staying in the background and getting her revenge on the pack that ruined her family.
***Disclaimer: I do not own Teen wolf or any of its characters except the ones I have created including Lena. I will create some events and take out some. This is my idea, so don't copy it. Hope you enjoy!
