Operators (NetOps, Ops, or Network Operators) are one of the two members of the duos of player characters. They are the human portion.
An 'Operator' is the person sitting on the real-world end of a PET-Navi connection, especially while netbattling. Every Operator has a PET, but not all people with PETs are Operators.
Operators live in the real world and use PeTs to jack-in to the Net with their Navis.
