Son of Captain Boomerang!


Owen is known among various circles as having taken over as Captain Boomerang after his father died. He is not as experienced but his powers made him quite capable. He dropped off the board though and hasn't been active with the Rogues for some time. More recently he seems to have dropped the "Captain" and the criminal activity.


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.

Character Details

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.



I thought I saw the devil
This morning
Looking in the mirror, drop of rum on my tongue
With the warning
To help me see myself clearer
I never meant to start a fire
I never meant to make you bleed
I'll be a better man today

I'll be good, I'll be good
And I'll love the world, like I should
Yeah, I'll be good, I'll be good
For all of the time
That I never could

My past has tasted bitter
For years now
So I wield an iron fist
Grace is just weakness
Or so I've been told
I've been cold, I've been merciless
But the blood on my hands scares me to death
Maybe I'm waking up today
