Carter Dorlan: The team leader of UPA Technical Squad 4. A long-time veteran agent with a background in administration, and almost approaching 40 years old. An unwritten UPA standard procedure is to shift its older personnel out of the field and into office positions, but Carter is fanatic about leading his crew directly on the field and taking a part in the actual work effort. His special ability is interviewing suspects and opening specially locked doors.

Andre Herderman: The engineer. A thirty year old former SkyRail engineer who joined the UPA a decade ago because he was laid off after boredom and bad attitude interfered and he was seeking something smarter and more exciting. He has violent anger issues and that shows in his love for picking fights with people like rioters. He was in the same train that injured Amber when he was young, which led him to become an engineer in the first place. His special ability is using the tool called the Omnitool to fix broken down equipment or machinery that must be repaired before becoming functional again.

Minoko Molensky: The Computer technician. She is in her early twenties and has been in Carter's team for over one whole year. She is a fast learner and very friendly and easy to get along with. She is a gifted person who shows off an in-born skill for computers, as early as when she was a little orphan, and she also shows off a careful calculating side unlike most young rookies. She tries hacking into the UPA systems as a part of her continuous training and practice. Her name means Child of the Minotaur. Her special ability is hacking into computer terminals, which let her control cannons, computers, cameras, heavy machinery, robots, tanks, aerial drones, factory lines, and information databases.

Amber Torrelson: The heavy support. She is a thirty year old Cyclops-class Cyborg. At twenty she was injured in a train accident, and the only way she could be saved was to be rebuilt with a giant robot body. This fit her fine, because she was already not very social by nature, and the robot body made it easier for her to keep her personal space while interacting with others. She is also knowledgeable in chemistry and physics. Amber's arm contains a combination gun that can shoot pulse laser bolts and missiles, and the missiles can also be upgraded to become homing missiles. Her special ability is being invincible to dangers like flames, poison gas clouds, electricity, lava pits, acid pools, laser beams, cold temperatures, vacuum, and high pressure zones. She can walk through those things without being ever affected at all.
