Killosus/Mr. Big: The man who broke Eileen Super-Nova (Patreon)

A boy without a name and without parents. Young Killosus Jacques [yes, that's his name] was taken in by an underfunded orphanage where he was exposed to a myriad of G.I. Joe and superhero action figures. The superhero ones were his favorite. The other kids bullied him for having a mask permanently stuck to his face, so he quickly gained the nickname Boy Without a Face, which actually upset him. He began picking fights with those who made fun of him and ended up winning more often than not and forced an apology out of those who harassed him. This taught him that strength mattered when it comes to righting wrongs that were done to him.

Because of this, however, the other kids left him alone and rumors would spread about his freakish strength which made him an outcast in an already divided orphanage. Even the workers would ignore him and leave him to his own devices, so he sought an outlet in crafting scenes with the action figures and toys that were left out. They were his everything.

As he got older, the ostracization began affecting his behavior and, using the knowledge he taught himself at a young age, would become a bit of a bully, attempting to force other kids to be his friend since his only real interaction with other people was always fighting to make someone who hurt his feelings apologize, thus making him lack social skills. He was too much of a dork for the other kids to accept him, but was too much of a brutish freak for anyone to feel safe around him and instead of teaching him or helping him, they just pushed him away. He also had very poor pattern recognition and it never occurred to him why.

As he grew older and wanted more toys, he'd resort to stealing them in secret. Because the other kids didn't care for toys, they let him get away with it which taught him that he could just take them if he wanted them. Nobody was there to smack his hand and tell him it wasn't his.

Once he began going through puberty, he gained a drive to work his muscles out as much as possible since everybody avoided him and he needed more than just playing with toys as an outlet to express his frustration. Growing bigger and bigger muscles, he became infatuated with himself and noticed that his body was perfection incarnate. Because of this, he decided to show it off more, often wearing the tightest tanktops he could get his hands on, just to show off his muscle definition.

Right when he became an adult, he decided to live his life by his own rules and would steal necessities like food, drink, and toys [they were necessities to him] because they were far too expensive and he wasn't going to pay for them anyway. He even used his real name while doing it...until he met someone who randomly called him Mr. Big one time and he loved it so much that he decided calling himself that.
