Abaddon bears a striking resemblance to the Eleventh Doctor, if the Eleventh Doctor were blond and prone to dressing in variations on dark jeans with chains attached and dark t-shirts under leather jackets. He has a tendency to change his hair around, whether by dyeing it or (once) shaving it off. If he doesn't pay attention, he's liable to sound a great deal like the Eleventh Doctor as well; when he is paying attention, his accent is pronounced, affected Cockney.
Abaddon was, at one point, the very definition of a rebellious teenager. It was during that time that he gained his dress sense and position as a PPC agent. The Cockney accent was an earlier acquisition, however. Since aging out of his teens, Abaddon has mellowed slightly, but more or less kept the dress sense. Rebellion aside, Abaddon tends to be quite content.
Abaddon has spent a good chunk of his life in the PPC. He was rescued by PPC agents as a child, from a badfic in which he, supposedly the young Doctor (despite resembling the Eleventh rather than the First), had been described to be so much like a human that he turned out to be one. By thirteen, he had a father figure in his life.
Abaddon became an agent as a teenager, and stuck with it. His most long-term partner is the Vulcan T'Zar, in DOGA, with whom he was partnered for a year beginning in March 2008, and then again from early 2012 to the present. One of his previous partners (pre-2008) was named Ancel and was, apparently, a moody fellow about twice Abaddon's age. Over his PPC career, he has become friendly with Dawn McKenna, a former partner of T'Zar's who remained close to her.
