Backstory
Starting with his parents, Mecho doesn't remember the face of his mother at all, having been raised in a foster home early on into his infancy. When he was only a toddler, that's when he was officially adopted by Arcadia. That's the mother he'll always remember.
When he was much younger than he currently is, he was always bright, quick to latch onto others and learn by watching them perform tasks. He often mimicked Arcadia or Urtė and took on a lot of their habits, but once he began to understand the world better, he diverted and had his own stand out qualities. He was very creative, into tinkering with objects. and praised for his work, he figured he'd like to keep it up if he can make something great enough to change the world even a little.
Learning alongside his peers, Mecho noticed he was accomplishing things faster, better, but he was never a vain or rude person. He offered help to others, always feeling that if he was good at something, those skills ought to be shared so a group can be great. He was something of a leader, a good friend to the other kids, a big brother. In his home, he was actually the littlest, the younger brother, just as happy being cared for by others. He got along well with his big sister, with his mother, never feeling as if anything else was missing. The thought of a father or of his birth parents never needed to cross his mind. All he'd consider is that when he's older he wants to mutually take care of his family more than he can now.
When he grows up, Mecho will become an engineer. He has visions of becoming a superhero currently, that being fiction, but a job itself won't constrain him to one lifestyle. Perhaps his hobbies will be just as involved, he could invent something on his own, he could do something alongside his community. There isn't one particular achievement he thinks is his greatest, always seeking to do more and more, countless good deeds.
