Nigel is a man of immaculate appearances. Between his black, pinstriped uniform, shined shoes, and slender build, he does his best to put forth the appearance of a proper, mature, gentleman. One wouldn't assume it, but all four limbs are prosthetics, covered by a thin synthetic skin that conceals their mechanical nature. Aside from his limbs, he lacks any sort of piercings, tattoos, or other permanent distinguishing features. Outside of his uniform, he tends to wear dress shirts and slacks, often with a pair of suspenders, due to not having much in the way of hips.
Nigel was born in one of the furthest north mining towns in Solitas, to a pair of parents who were perfectly good, fine, normal folks. Despite the generally poor economic state of a mining town like theirs, they did well enough, since they were one of the few places that had access to booze. Things went well enough for the family and their tavern, aside from occasional trouble from unruly patrons, and the occasional protest from the mine workers. But that peace was not to last, as the small town was in for a disaster when the child was only three years old.
During a severe snowstorm, the small town blacked out, cutting it off from communications. In the confusion of the storm, the Grimm attacked. Or more specifically, one single Grimm. A hulking, humanoid form with a hunched, lumbering gait, the slow approach of the seemingly invincible monster is one of the few sights that Nigel would be unable to forget as he grew older. Its arms effortlessly collapsed buildings with a single sweeping motion. Civilians like his family had to flee their homes while hunters did their best to fight the massive creature. They failed however, and the people were forced to weather the blizzard for several hours before atlesian air support made it on the scene for evacuation while the beast raged through their city.
Hypothermia and frostbite were common among those that escaped, due to the sudden nature of the attack, and a lack of preparation. Especially among the most vulnerable people, like Nigel. Despite the best efforts of professionals, Nigel's frostbite was severe in all four limbs, and months after the attack had to endure amputation, a particularly difficult situation for such a young child. The physical therapy, medical bills, and replacement of prosthetic limbs due to his growth was a massive strain on his parents, putting them deep into debt. They recieved some help from charitable contributions shortly after the initial attack, but it had next to no effect on the enormity of bills the family would face. Not only that, it was a vicious cycle for Nigel, who was in and out of medical facilities, having to go back to square one every time he outgrew his arms and legs.
When he could, he joined up with Helios academy as a route to get to Atlas Academy. He didn't particularly want to become a hunter, or join the military, but he saw the pain that his parents had to go through to keep up with his limb replacements, and decided on his own to do something about it. The military took excellent care of their people, at least in a medical sense. And if he went through Atlas, he'd have a guaranteed job. All in all, it seemed like a decent plan to the thirteen year old, his parents reluctantly agreeing. Eventually.
By the time he had been put into Atlas, he'd been pushed and molded into a fighting machine, despite his disability. The past four years had taught him how to fight, weaponized his prosthetics, and put him on the path of a pilot. Atlas Academy continued that education, as the young man was given advanced instruction on how to pilot nearly every vehicle in the military's arsenal, land, sea, or air. Helios had revealed a talent in him for being able to drive just about anything, and Atlas had no intention of letting such talents go to waste.
Unbeknownst to him, he was being put on a special assignment due to a combination of convenient factors. A forming hunter team had a VIP that needed additional protection. Nigel's piloting skills were a useful asset, but more importantly, he was the perfect age to be added to the team. Thus, he was placed within team PSLY, lead by one Miss Penny Polendina. They never told him about her, of course, and with his education, he hadn't questioned why she was the team's leader. No doubt she was strong, but her impulsiveness and naivety seemed to be at odds with the qualities of a leader, at least in his opinion.
The incident at the Vytal Festival shut those concerns down, though. While he was never given the whole story, he understood enough to get over his apprehensions, and to understand his place within the team.
