Earth-side
In order of appearance…
Hollow/Foxtail
HF, for short. An artificial intelligence self-contained in computer units carried in a (well-armed) semi-tractor-trailer rig. Whether or not he has backups of himself somewhere else is unknown, but part of the reason that HF is not in a bunker somewhere is that it worries about being re-taken and it's powers abused by it's creators (it destroyed all of it's backups when it went rogue). It now roams the country, keeping hidden, and seeks to disempower it's creators. It sees friendly humans as useful extensions of itself.

Sheriff Dan Oakley
Oregon County (the county in which Alton is located) Sheriff. Large and in charge.

Lone empathic crusader against the conspiracy, Ron Deering is a federal Marshall usually tasked with transport of prisoners.
