- "Cayden James is 20 times more dangerous than Snowden. We caught him trying to hack an A.R.G.U.S. transponder. If he got in, every NOC agent we have could be at risk."
- —Lyla Michaels on Cayden[src]
Cayden James is the leader of Helix, an organization uniting masterful hacktivists. Although no official case was formed against him, he was denoted as a "person of interest" by A.R.G.U.S. and imprisoned in a black site facility. Cayden's Helix allies, led by Alena, eventually rescued him with the help from Felicity Smoak.
At some point Cayden found Helix, an organization uniting hackers that pursued political activism. Considered by A.R.G.U.S. to be 20 times more dangerous than Snowden as a security risk, Cayden James was captured by the organization when he was supposedly trying to hack an A.R.G.U.S. transponder. Also his crime was not proven in court, Amanda Waller gave the order to keep him imprisoned as a "person of interest". Cayden was moved to a black site prison, which was eventually located by his Helix allies in 2017. The Helix rescue team led by Alena and Felicity Smoak ventured into the facility, opposed by A.R.G.U.S. security force and Team Arrow. They successfully extracted Cayden and moved him to an undisclosed location. Back in the command of his organization, the Helix leader decided to cut off ties with Felicity, considering her ties to Team Arrow a liability, but worked with the code to figure out a program she was looking for that would allow to locate Prometheus's location. Leaving a flash drive for Felicity's use, Helix evacuated from their old base to a new location.
Cayden is likely close with Alena, who became immediately distraught and very concerned for Cayden as soon as the Helix team found him, losing her cool. He is also a very suspicious individual, ordering Alena and Helix to cut ties with Felicity altogether after being saved, not trusting an individual affiliated with Team Arrow.
Powers and abilities
- Expert computer hacker: Cayden is a highly skilled computer hacker, so much that he was able to hack an A.R.G.U.S. transponder. His abilities made him a "person of interest" for A.R.G.U.S. and a security risk considered 20 times more dangerous than Snowden. As soon as he was freed from captivity, he managed to immediately figure out the code for the program that Felicity needed, but neither she nor Alena could figure out on their own. According to Alena, he is the best hacker on Earth One so far that no one has ever heard of him. His skills surpassed those even of Felicity's hence making him one of the best hackers and one of the most intelligent individuals in the multiverse.
- Leadership: Cayden not only created and ran Helix as a powerful organization, but also inspired loyalty into hackers under his cause, so much that they staged a massively dangerous operation to rescue him from a heavily guarded government facility.
