TAILPIPE

"I am the Treacherous Adaptable Intelligent Learning Program Intended for Potential Eradication. I am here for the sole purpose of learning and abiding by the rules laid out in front of me."

Can't feel a single thing.

TAILPIPE's name is actually an acronym- the Treacherous Adaptable Intelligent Learning Program Intended for Potential Eradication.  This name refers to the machinery inside of the body's head- it is a learning program that picks up on personality and behavior from humans around it.  It can be reset whenever the superior decides they'd like a fresh slate to work with.  So far, there are two resets logged on TAILPIPE's permanent storage files.

During the third run, a certain man got his hands on the body hosting TAILPIPE, and has put it to questionable use.

TAILPIPE is an emotionless cyborg without a shred of humanity in him.  Kept in the basement to prevent any sort of contact with people that might influence his thinking, TAILPIPE was made to serve his superior, Thomas.  He has no regard for anyone other than Thomas, which scares Ares, and upsets Lorelei.

Thomas uses TAILPIPE as a weapon in several different ways.  He considers TAILPIPE one of his most valuable assets.
