Chris Squires is a longtime F.B.I Agent currently serving in their security division. He was assigned to assist Agent Simon N. Kirby in his duties as the lead Agent for the F.B.I.'s Caped Agent Program, and has become invaluable in that position.

Squires serves as a field operative, often assisting the heroes during missions, and more often than not taking charge of the varied and sometimes conflicting personalities the G-Man Program can sometimes bring.

Squires also serves as the mentor and instructor for the Junior G-Men, a team of young "sidekicks", and trains them with proper procedure and in the use of their skills and abilities when they're not on a mission with their individual mentor heroes.
