"Well, Helix is a worldwide operation. Kinda like the UN if it actually accomplished things."
Alena Whitlock[src]

Helix is a group of hackers founded by Cayden James. The organization's status remains unknown.


At some point, Cayden James founded Helix, an organization uniting hackers that pursued political activism. Sheck and Alena Whitlock later joined Helix. A.R.G.U.S. considered James to be "20 times more dangerous than Snowden", labeling him a security threat. Some time later, A.R.G.U.S. arrested James.[1]

After Alena noticed someone who appeared to be Felicity Smoak attempting yo hack into the N.S.A., she contacted her via terminal message, offering her help. So, the two soon met in real life and Alena explained Felicity's inspiration to her, before handing her the USB flash drive known as "Pandora", hoping to not only exonerate her friend but to inspire her to return to her hacking roots.[2]

Later, they supplied Felicity with a huge data bank that included the files she needed to get John Diggle out of military prison and blackmail that she used against a Bratva member to gain information about the phone of General J.G. Walker in order to track him down in Russia.[3] They also helped get proof that Adrian Chase is Prometheus.[4]

Helix tried to track down Chase on Felicity's request, although A.R.G.U.S., Team Arrow and the police were already involved in the search. Alena came up with the idea of rescuing their founder, James, who is imprisoned by A.R.G.U.S.. After rescuing James with Felicity's help, they realized that having her in the group was a liability, as she was connected to Team Arrow. Thus, they have relocated to a different location, but not without leaving Felicity a parting gift as a means of thanks.[1]

Shortly after Cayden James and Helix joined several criminal gangs like Ricardo Diaz's organization, Anatoly Knyazev's "exiled" branch of Bratva and Black Siren's group, Alena left the group.[5]

Following the death of Cayden James at the hands of Diaz,[6] the organization's status remains unknown.

Then, Felicity and Curtis formed a new group called Helix Dynamics,[5] which later became Smoak Technologies.[7]
