Chell from Portal.

The hell priestess decided that the first person in her Human Centipede should probably be someone who is willing to follow directions and not talk back. Thats when she decided on the main character from the video game series Portal, Chell.

The priestess walked over to the machine and programmed the character Chell into it.

Chell woke up tied down to a gurney, unsure of where she was and how she got there. Last thing she remembered she had just escaped from Aperture. She started looking around trying to figure out anything about her current situation when a voice spoke up, breaking the silence of the room she was in.

"Hello Chell. You're probably wondering where you are and why you're here." The priestess stepped forward revealing what she looked like to Chell, much to her shock. "For the question of where you are, that is irrelevant. All that you need to know is that this is your new home. And as to why you are here, well the answer to that can wait." The priestess smiled for the first time in a very long time, anticipating the horrified reaction of her playthings when she reveals what she plans to do to them.

But that could wait. After all, why spoil the fun so early.

She caressed Chell gently on the face. "Just know that you are now my pet and you will belong to me for the rest of time. Now your mistress wants you to get some sleep while she works." The priestess injected a sedative into the I.V. in Chells arm which soon caused her to drift off.

"Now who's next," the priestess thought to herself.
