Goosebumps haunted mask and supergirl

Chapter 4 - ending

"Kara! STOP!" she thundered. J'onn and several other DEO agents were with her. "You need to stop this! Come to your senses!!"
"Sorry, but the old Kara can't come to phone right now!" Kara replied with a savage and mocking laugh, voice still low and raspy due to the mask.
"Take off that mask!!" J'onn commanded.
"Or else what?!" Kara sneered back down at him, fanged mouth twisting into a hungry smile.
"This!" he replied, jumping straight up in the air to chase after her. But for once, it wasn't enough. Although J'onn was one of the strongest things on the planet, Kara's newfound rage had given her such a boost in strength and brutality that she was actually able to evade J'onn quite well.
"Loser! Slow poke! Old man!" Kara taunted through her distorted voice. J'onn ignored her taunts in a continued to attempt to talk her down from her savagery. It was of no use. The more he tried to talk her down, the more monstrous she became, continuing to insist that the old Kara was dead and gone forever and that this new vessel and machine of hatred was all that remained.
"Take off that mask!!" J'onn repeated angrily.
"It is not a mask!" Kara shot back. "Not anymore!!"
But just when it seemed that nothing could stop Kara's rampage, Alex finally appeared. With a Kryptonite Sword in hand, Alex snuck up on Kara right as Kara was in the middle of taunting J'onn. One quick swing was all that Alex needed and then that accursed mask came off of Kara's body the hard way. Kara's head, with the mask still firmly in place, landed not too far away from where Winn and Lyra's bodies lay, ironically enough. J'onn managed to catch her body before it hit the ground. Alex, meanwhile, fell to her knees, sobbing as she dropped the bloody Kryptonite Sword in anguish and defeat. She knew she would live through this nightmarish event, but not without a lot of mental scarring.
The night had not been happy at all, but it most certainly had been Halloween: chilling and hellish, filled to the brim with death, despair and darkness. Even though Kara was dead, body quickly disposed off as the cops finally arrived to try and set things right once again, the mask remained firmly upon her severed head and its eyes seemed to gleam and glow a bright golden long after the night was over.
