For it to be on the CW and actually look good you almost have to go with a non powered or powers that don't take a lot of effects to pull off. CW is cheap. Just look at how many times characters with flashy powers actually used them in something like Legends. So you need more a street level fighter type. The best bet would be characters like the Question, Huntress, Manhunter, any one with that type of power set and skills. I do like the Deadman idea though.
