Hey,
Sorry for the late response, I got carried away with work. I've linked my accounts.
I will talk more about Sergio since he is my main character.
Sergio was an urchin who was inducted into a local gang at a young age. He is no stranger to violence and cruel actions. However, after one too many messy incidents he decided that this life was not for him. So he took off and started doing side gigs while he figured out his next plan.
He found temporary work as a club bouncer, while doing volunteer work for an orphanage during the day. A part of him did not want other young people to walk the same road he has and it aligned with his inherent goodness.
Eventually, like everyone else, his fortune would point towards the stars and he set out to seek a new life.
Sergio is an amicable, kind person. So when interacting with others he treats them with respect as long as they are also respectful. He is also prone to helping others in need almost to his own detriment, as space is a dangerous place and not everyone has the best intentions.
During conflicts, Sergio is the kind of person to resort to violence as the final answer, preferring to solve problems using his words first as he has hurt enough people needlessly.
As for preferred occupations, Sergio is a big guy so he would tend towards physical jobs than mental ones. Working in salvage, dabbling in engineering or on occasion doing contract work as hired muscle as a call back to his former life.
