I could change my character, it would be no problem at all.

If your guys are stealthy and/or combat experts and enhanced humans, you'd likely be in the JL Task Force under the leadership of Martian Manhunter, or you would have been involved with the JL International under the leadership of my Capt. Atom as he worked in affiliation with world governments. The JLA is for the more flashy superpowered folk.

I really don't know. I can't even understand what his character's backstory was. And I've tried reading through it twice.
