Agent Helix is a character from the G.I. Joe series, G.I. Joe: A Real American Hero. She was designed by Mayan Escalante, a character artist at Double Helix Games, as an unlockable character in G.I. Joe: The Rise of Cobra (video game). She then became an action figure in the 2009 edition of the toy line. Agent Helix is an alpha-level G.I. Joe operative, one of Hawk's special projects.
Agent Helix is a covert operations officer for the G.I. Joe team. She is an expert marksman and skilled with advance martial arts training. She uses duel 10mm Autopistols as her preferred weapon. She's an Olympic-classed gymnast and uses her distinctive "Whirlwind attack" to deliver overpowering combinations of kicks and firepower to Cobra agents. Has the ability to identify and solve complex physical calculations at a rate that some consider extremely spooky. To her, everything has a data set, like miles left before a car will run out of gas or ammo count in the bad guys' guns, etc. To Duke and Hawk, this ability is called "Total Organic Battlefield Awareness."
Prior to joining G.I. Joe, Helix was a near master level practitioner of capoeira, muay thai, wing chun, shuai jiao, kendo and even fencing. Helix competed in both official and underground tournaments. Some of those tournaments were to the death. She would walk in the tournaments knowing nothing, engage in combat with lifetime practitioners of the art... and walk out without a scratch. Not only was she a good fighter, rumor had it that she could master a fighting style after encountering it once.
- Helix was a character developed specifically for the Rise of Cobra videogame, but was simultaneously introduced to the IDW comics.
