Peridot and Obsidian had what you would call a "normal childhood" in a middle class family. Their mother was a 'stay-at-home' type of mother while their father was the one working to keep the family fed. From an early age the two twins were inseparable, Obsidian - showing rather great strength already as a kid - always helping Peridot out of the trouble he had gotten himself into when lying his head off to impress the kids from their block or school with his ridiculous stories.  

When the boys were in their mid teens, their parents separated though not on a bad note. Not wanting to choose either of their parents, their parents decided to live rather close by each other so that the twins could move between them every other week. 
 
After high school the brothers, who to this point had been inseparable, decided to go their separate ways to find out what they wanted to do with their lives. Obsidian quickly found his call in the darker parts of Junction City - Underground fighting which later even earning him a job as a bouncer at a club. Peridot on the other hand, had a lot of different jobs in a few different cities under this span of time - one of which included driving a weinermobile. He took these jobs because he though they seamed fun and once he lost interest - he would quit if he didn't get fired first. 

A little more than a year later Peridot ran into his brother - quite literally - the big MTT once again saving his brother from getting his scull kicked in.  After getting each other up to speed, the brothers decided that they both had had enough time apart and settled on sharing a flat. This is when Obbi got the knowledge of Peri's new line of work as a (pretend) "psychic medium" in hope of earning some good money and choose, being protective of his twin, to help (or to be precise: keep him out of trouble) his brother with what he was doing. This is where they are still to this day - a pretend psychic medium and a bouncer conning Junction city.
