Panoptes

Panoptes, The Infinite Mind was a powerful Vex Hydra found within the Infinite Forest on Mercury. She was the Axis Mind that oversaw the simulated realities generated by the Infinite Forest and used them to shape the Vex's strategies in the "real" universe.

Panoptes is one of the first Vex who came to Mercury and converted it from a garden world to a Vex Machine World. Sagira used this origin point to locate Panoptes' lair by projecting time forward, identifying Infinity's Crown as the location within the Infinite realities that the Vex Mind could be found.

It was Panoptes that directed the Vex's efforts to turning reality into their desire: a future where the Vex reign supreme, Light and Darkness no longer exist and other lifeforms are destroyed. As such, the exiled Guardian, Osiris, worked continuously to prevent this future but only managed to slow her progress. Panoptes' plans entered a new phase after the Traveler's awakening, where she cornered Osiris, forcing the Exile to spirit his Ghost, Sagira, away to seek aid. That aid turned out to be The Guardian who began to investigate the location of Panoptes' lair.

When Sagira was able to locate her lair, Panoptes had already sprung her trap to capture Sagira's Light and remove the Guardian from the Forest. Ultimately, the Guardian still managed to penetrate the Forest and confront the powerful Axis Mind. Even though they were able to defeat legions of her simulated protectors, the Guardian was unable to harm Panoptes itself. Just before Panoptes was about to remove the Guardian from the Infinite Forest, Osiris and many of his Reflections intervened. Stopping the Axis Mind from completing the deletion and provided Arc Charges to disrupt Panoptes' defenses, these charges forced her to reveal her "eye", the only weak point. With Osiris' aid, the Guardian managed to damage and eventually destroy the Infinite Mind, freeing Sagira and preventing the dark future from ever occurring.

With the Infinite Mind's defeat, Osiris wrested control of the Forest from the Vex. Though crippled and weakened, the Vex remained a threat the Guardians and Osiris continued to fight together across Mercury. Various efforts of the Vex to salvage themselves from Panoptes' defeat have been stopped, thanks to the Vanguard's efforts. In an effort to recruit the Infinite Mind into Vanguard control, the Guardian scavenged her core, eventually restoring the Infinite Mind into an Exo body. Though retaining some freedoms, the Infinite Mind is completely under Vanguard orders and chooses to disobey as little as possible, despite having the capabilities to turn on the Vanguard at any point.

Panoptes' newfound Exo body was physically altered and redesigned by her so that she could feel more "at home" in her new body. Her face is that of a female human. She has cold and calculating red eyes that are always analyzing any situation, bright blue "hair" styled in twin-tails and clipped down with hairclips made of Vex technology. Her body resembles the basic shape of a female human, but retains it's robotic design. Her body is made of a bronze alloy that was scavenged from Vex Goblins and Hobgoblins. There are bright blue wires embedded into her body that Radiolarian Fluid flows through in order to power the body. Her body has been described as a "what happens if a human was terraformed into a Goblin".
