Bob Layton explained the style of the series: "When David [Michelinie] and I set out to do H.A.R.D.Corps it was because ... We like light-hearted, hard hitting, bash 'em in the face, sock 'em guys.

The neural implants utilized by Omen Enterprises allow the team members to mimic the powers of Harbingers, and are all assigned and managed by an operator named "Softcore."

The original team was composed of former fighter pilots and went by call signs in the field, starting a Corps tradition of using codenames.

In new continuity powers are supplied to operatives via Lifeline through their reverse engineered Harada Tech neural implants developed by Project Rising Spirit.

The Implants are also wired to explode and can be detonated automatically either upon capture or death of operative and remotely from PRS home base.

Corps demonstrate include: A special store of one off powers called Bee Stings can be issued, but are adeptly named due to the fatality ratio making them useful only once.
