Background: Seth Javier Carrera was born into a military family. Some of his earliest memories are of his father, Tony, building engines in the garage. On of the happiest days of his childhood, was when his father asked if Seth could help him in the garage rebuilding the engine on his prized '67 Chev Impala. He was, however raised, primarily by his mother, Marea, and his siblings while his father was on deployment.

It was inevitable that Carrera enlisted in the Corps when he was of age. During his basic training, the Carrera family was informed that Tony Almedia Carrera was killed by an IED, it was at that moment as he stared into his father's commanding officers eyes, that he decided to become an EOD. Carrera's instructors soon determined that he was a prodigy, and had an innate understanding of the mechanics, wiring, and trigger of any device he was able to examine.

Seth and his unit were deployed in the Middle East, working under NAVSOC, Navy Special Operations Command. Some time into their second tour, Carrera's unit was ordered to investigate a manufactoring facility that was supplying advanced munitions to local insurgents. On entrance to the facility, Carrera's team met heavy resistance from unidentified mercenaries with blaster carbines and high tech gear. The SEAL team was able to neutralize the troopers, though not without taking casualties. That was when they discovered a device, one which even Carrera had difficulty recognizing.

The device held a perfect sphere of magnoplasma in suspension through a series of polarized magnetic fields. Carrera was unable to determine the frequency of the fields, the magnoplasma was highly charged, and unstable. While attempting to disable the device Carrera was shot in the shoulder, the focused plasma packet interacted with the magnetic fields, causing them to collapse, and the magnoplasma to explode. The resulting explosion knocked Carrera unconscious, the team retrieved their fallen comrade. They commandeered a vehicle and extracted their casualties, fighting a running battle with the Sala'aq troopers as they withdrew towards the LZ.

Minutes out from the LZ, the insurgents launched a surface to surface missile towards the SEAL teams vehicle. Carrera, his bio-electrical field infused with magnoplasma, felt the missile and reacted. With a thought the shape of the missile twisted, flying apart into it's component pieces. He then turned, and with a wave of his hand sent the shrapnel from the missle at their pursuers.

The team was able to be successfully extracted, though Carrera was returned State side due to his exposure to the Magnoplasma. He was transfered to a PSB medical facility, where he was treated, and learned how to control his new found abilities.

During his debriefing with Cmdr Parsens, he learned of Sala'aq's involvement during his unit's last mission. While he felt helpless, as he recovered from his injuries, he soon learned that affiliates of Sala'aq had begun to target the familes of the members of his unit. Determined to protect the families of the men and women who had risked their lives to save his own, Carrera took the name Magnaflux, and began to strike back against Sala'aq's operations in Florida.
