ZedRec

"'If it would make you feel better, I can run a diagnostics test to ensure I am fully operational.'" Zed-Recorder, ZedRec, or just Zed for short, is the upgraded form of the security system. He was built to make the security more efficient, and to give it a personality and voice so the users felt more at home with the security overlooking them. They cannot move from their chamber, but have access to all security cameras and functions, and can move freely in the digital plane to confront threats.

History
He has not existed for very long, but was initially created to help keep a close eye on the actions of Natthew Batrick, also known as NatBat. His personality seems to be very logical and straightforward, and he is highly intellligent. His access to internet databases means he can answer any question with relative ease, or inform the asker if he cannot.

He constantly scans all of his drivers and chips to remain up to date, sending an analytical report in the case that he finds something has gone wrong. The only large flaws in his programming are being mainly linked to the entire arena power grid (thus causing an outage if he goes offline) and his entertainment chip stopping him from teleporting away threats he finds humorous.

Trivia

 * His name is short for Zed-Recorder, as he can calculate an impressive 26 different scenarios for any given situation.
