Terrence was son of a little known English Superhero duo of mutants Mr V and Scarlett who were also a couple in real life.
Mum and Dad loved Terrence very much, so much that they continued fighting crime to make the world a better place for their little one to grow up in.
Unfortunately Crime and Disasters don't keep a regular schedule and his parents day jobs couldn't afford a 24 hour a day Nanny, so the Television would have to do.
And what did Terrence love to watch? superheroes be they in documentaries, cartoons or movies.
But one day at the age of 11 Mum and Dad didn't come back leaving Terrence on his own and put into care of the government while they tried to find him a new home.
This was when his powers hit
Shapechanging powers! a power that lends itself to pranks and hoaxs that troubled teenage boys are prone to.
This made Terrence difficult to find a home for, he would pull pranks like hiding as a lamp in his room when potential foster parents visited or even when he was adopted once or twice the pranks he would pull would ended up with him being dumped back at the foster home.
His only constant companion in these times was a hard women the name of Mary who was the cook at the adoption home he lived at for most of his teenage years.
Terrence's pranks had other consequences he shifted schools many times but this did lead to one good thing he got the oppurtunity to practice at making friends quick and he did this over and over again with new kids from his latest school or the newest additions to his home at the orphanage.
But still over all these years the TV was always there for him and his impersonations of TV characters were always his most popular, over the years he lost any ability to change into anything which wasn't Television, his actual outward confident character being an act itself.
At the age of 16 Terrence received an average bunch of GCSE results (for a bright boy like him anyhow) and proceeded into A-Levels (average again) and then University taking a course in media studies focusing on what else but Televisual studies resulting in him just scraping a Third.
After that he managed to go through a bunch of jobs in television starting off as a tea boy helping out with cameras and props for a number of different companies, during this time he decided to do something with his powers other than scoring cheap dates with girls he started a number of minor viligilante acts scaring off punks at the local parks by turning into pro wrestlers, because they had annoyed him, turning into Buffy (aka Sarah Michelle Geller) coming on to a lad and then turning him down because he was "asking for it".
He also saw the advantages in his powers and as his job had taken him to London he thrived on turning into TV celebrities to get free access to glitzy events but this is where it landed him in trouble one night after changing into the latest winner of the last celebrity reality TV show to get into a swanky up market club for free the actual guest was present, the door staff had collared Terrence before he could make his escape and the old bill were called (old bill = police).
A few hours of grilling from a police detective who had been making a list of these suprising celebrity appearances (not all of them spotted correctly, mind) and the big boys were called in MI6's super power division Super Power Investigations SPI (pronounced spy, see what I did there

) for short, Terrence was young, and is reasonably gullible the agents hyped up his crimes and coerced him into working for their agency.
A few years later and they gave up on him citing his unpredictability, excessive showmanship and inability to keep quiet as reasons why he wasn't suited for them, over the years they had assigned him to various shrinks and doctors to try and figure out why he could no longer transform into anything he liked, especially other heroes but the results were for naught.
Freshly unemployed and looking for something new Terrence Vance tried a number of "heroic" endeavors both solo and as a team (under a variety aliases, broadcast and Telly addict being two of them) but they didn't really work then he hears about a TV show looking for supes, someone up there must be smiling on him he thought as he grabbed a mates cam corder and started work on his audition tape.
