Owen Mercer grew up in a variety of foster homes, sometimes loving caring environments, sometimes less so. He had no idea who his parents were or anything about his background. He grew up in the streets mostly, getting into limited amounts of trouble, trying to prove himself whenever possible.

Around the time he was twenty, and working at a dead end construction job, he met his real father. Not only did he have a father, but he had a super villain father! It was like a dream come true for a tough kid. He and his father slowly bonded, of course his father really only knew how to bond over a few things: boomerangs, crime, and booze. Owen was introduced to the Rogues around this time, and found himself having a real "family" of sorts.

Things fell off the rails when his father accepted a job to assassinate a hero's father. Somehow Digger wanted to prove that he was more than a lower level villain. He wasn't. He died in the process, but still managed to kill his target. Unsure of how to handle the loss, Owen did what he assumed was the right thing and took up his father's mantle. He pulled many jobs with the Rogues and some independent contracts. At first it was a thrill to prove he could do it, but as time wore on he found himself disillusioned with the effects of his "career."

After landing in prison for a second time, at a real maximum security outfit, Owen heard about a way to redeem himself. He managed to volunteer for Task Force X. At first they weren't even sure they wanted a second rate version of a second rate villain, but Owen persisted. He trained with the squad and became a somewhat willing member. Having done enough to merit a pardon, he left for NYC, far away from his home in Gotham and hopefully far away from Robin and his old man's shadow.

Recent Events

And while Owen has made some progress in changing his life for the better in some areas, he still remains firmly entangled with issues from his former life in many others.

Over the last year Owen has managed to find a steady normal job working at Luke's bar, nearly die when that bar exploded, find out his coworker is actually his half-brother and that they are both time displaced from the future, relapse, rehab and repeat.


Owen didn't have an easy childhood, and his personality developed as a way to deal with his difficult situation. Deep down he wants desperately to be a good person, someone that people can look up to, can appreciate. However more often than not what comes out is a scathing sarcasm, meant to insulate him from any criticism or hurt. He flirts and jokes, often willingly pushing people away. He pushes back against authority, but respects it immensely when wielded properly. He has had to be independent his whole life, but wishes he had other people to truly rely on. Unfortunately even his "family" has proven themselves selfish and only interested in him if it helps their cause. He's not an easy person to get to know, but if given a chance he's fiercly loyal and protective of anyone he considers close.

RP Hooks


Owen is a full time bartender at Luke's bar. You need to come vent to someone about your "lady problems", assuming those lady problems involve a murderous band of female ninjas trying to sacrifice you to some elder god, Owen's your man.


Who do you know that has drug dealers on speed dial? Who can find you a fence that might know something about that missing painting of the governor in the nude? How can you get an in to that underground casino that only accepts bets in obscure latin based codes? Owen has many weird and strange such connections that he might occasionally leverage.

Secret Secret Agent

Owen is a part of the Suicide Squad, those ne'er-do-wells who are called on to do the unmentionable in unattractive lands. Crossing paths with legitimate agents in places he shouldn't be is just a hazard of the job.


If something is going down in Hell's Kitchen and to some extent NYC at large, Owen's been drafted into a team that has not so much sworn to protect the neighborhood as generally agreed that someone should do something.



Character Sheet

Speed Burst

Owen is able to move at superhuman speed for very limited amounts of time. He can easily break the speed of sound but only for a few seconds at a time. He mostly uses this to throw boomerangs or other throwing weapons at incredible speed. He can also use it to run, dodge, and move at super speed as well. He can dodge bullets at point blank range or even run and catch a bullet in flight. He also has a handy protective aura from the speed force during these movements that allows him to throw super human punches without shattering his bones, or run super-fast without being subject to usual friction / drag.

Speed Effects

Owen is able to use his speed bursts to speed up his own natural healing (ie heal bones faster, no regrowing limbs). He can also use speed bursts to shake off the effects of poisons, gasses and more often drugs, alcohol and hangovers much faster than normal. He has to consciously use speed bursts to do this though, it doesn't happen automatically. Using his speed this way means it is less available for other purposes, and he has to replenish food and liquids more.


Over the comms, "I'm sorry Batman, I couldn't hear you say how f***ing great you are. You cut out there. Need a hand?" Because Captain Boomerang is a dick. And it's really fun to offer to help Batman.
