Nicanor grew up the oldest of five in the city of Aguascalientes. His family, migrants from another state, had the American dream: As long as he could remember, his mother, a nurse, was waiting for a green card and his aunt, a naturalized American citizen, would sponsor visitors' visas for the family to come and visit her in Colorado when they could afford it. His father also worked long hours first at a hot spring and later in a hotel, so while his parents were able to put just enough food on the table, looking after his siblings often fell to Nicanor as he was growing up.
In 1999, Nicanor met his partner, Bakumon. Most of his siblings thought this was awesome, but his closest sibling, his one year younger sister, pointed out that he couldn't be the only one this had happened to. With his family's help, Nicanor was eventually able to track down the other Chosen. Among the oldest of the Mexican Chosen, Nicanor was encouraged by his parents to lead them, but they were too spread out to do much more than occasionally hang out, so he mostly ended up worrying over them from a distance.
When his mother got her green card in 2000 and moved to Denver, Nicanor was forced to take on an even greater role looking after his siblings. He still tried hard, if usually unsuccessfully, to balance his role as caretaker with his role as Chosen, dragging his siblings along to meet with the other Chosen.
Though Nicanor was fully aware of the wild Digimon at Christmas 2002 and had passed the message on to his fellow Chosen to round up them up in a central location, Nicanor, always one to follow the rules, obeyed the children's curfew and stayed at home looking after his siblings. When the earth was plunged into darkness a few days later, he was too busy trying to comfort his youngest sister who was scared of the dark to notice that his digivice was glowing. Hearing from Rosa that the day was saved by her and some Japanese kids made Nicanor feel like a bit of a failure: He was among the oldest (he was almost thirteen at the time) and he'd left saving the country up to a little girl and some foreigners. From that day on he quietly harbored ambitions of joining the armed forces to try and make up for this.
In 2003, his mother's applications for green cards for the rest of the family were finally processed, and Nicanor, his siblings, and his father joined her in Colorado, where Nicanor transferred into an American high school. He lost a lot of contact details for his old friends in the move, and he lost touch with them; it doesn't help that a lot of them seem to have moved. With the family back together again, the kids growing up and more able to take care of themselves, and his parents able to take on less hours at work, and without any other Chosen really around, Nicanor suddenly had some free time in which he joined the local Boy Scout troop, reaching Star Scout in his junior year of high school.
Seeing as it was her nursing education more than her sister that got her to the United States, Nicanor's mother insisted that he go to a four year college. The family became naturalized American citizens in 2008, which made Nicanor eligible for an NROTC scholarship covering his education and a monthly allowance to Auburn University in Alabama, where he started in 2008 and majors in mathematics. This scholarship means that he takes naval science courses along with his degree, goes to training twice a week and in the summers, and will have to serve a minimum four years upon his graduation and commission as an Ensign in the Navy.
Recently twenty-one, Nicanor just finished his third year at Auburn. He works hard in school and with NROTC, which interferes quite a bit with his being an otherwise doting, chivalrous boyfriend to his girlfriend of two and a half years, but he loves NROTC and his fortunately also very busy girlfriend.
