Shank the Tormentor

Background
Shank was a regular child, minding her own business until one day, her universe crashed with two others and she found herself in another version of her own living room, face to face with two other Kaitlyns. This was The Creation of the Trios, and it made her mad. Filled with rage, she attacked her counterparts, but even after striking them both down, they came back to life. The next morning, she fled from the police and traveled across the United States.

Biography
After the Trios Tragedy, you'd think this was the end of her story. But you'd be wrong. About a month after her death, Shank came back. Delighted to be alive once more, she set off on an adventure, forgetting all about Green for a while. But one day, she received a note. A burst of scarlet flame revealed a letter floating next to her. When she read it, she became angry. Angry at the world, angry at herself, angry at Blade. The note was from Blade, letting her know that Green was no more. That he had died again while she was gone. In her rage, she dropped everything and Attacked Blade. She and Blue set out on their Search for Green. Broken and dejected, Shank returns to the house in Maryland and lays on the couch to heal. Feeling pathetic, she jumps at the chance to heal early and Becomes a Tormentor. She sticks around for a while, doing her job, even when Blue goes missing during Red's Misfortune. When Blue returns to kill Blade, who is still weak from fighting Shank, he manages to break Vanilla's hold over his mind and becomes himself again. But, of course, it's still Shank's job to kill and revive him every day, that is, until Blue is Forgiven. No longer having a job, she wanders the world. But having witnessed Blue attacking Blade, she knew Green would be back to fight her as well. Green's Final Death takes place and Shank begins her new life as a serial killer. By the body of each victim, she leaves the letters StT traced in the dirt. She's still out killing to this day, Raffles by her side the whole way.

Abilities
She's been a Soul Snatcher her whole life, so she's been taking souls for a while now.

Her choice of weapon would be knives. Throwing knives, daggers, any knives will do the trick.

When she became a Tormentor, she gained a whole new power set. She can phase through matter, walking through walls and occasionally people. She can also summon weapons from thin air. And by weapons, I mean pretty much anything. Including bricks if necessary.
