I don't think it would make much of a difference. Parallax would make him physically stronger since he can only amp his host to a degree which is under Prime's base physical abilities. He also wouldn't benefit much from the energy manipulation considering how mentally unstable he is. He would also be suppressing a lot of Parallax's power in order to stay in control. The Butcher entity is a different story.
now you are cruel you want to give him the rage entity at least he is limited a bit with this one LOLOL no lie that would be epic though.
oh great now he will get way more ass from woman than every b4 oh lord. Still how would him being a spy make sense whene every bad guy will already know who he is though. Oh well i guess i'll wait and see.
In terms of importance within the DCU, Black Canary was extremely up there pre-52. She was put over Wonder Woman in some stances.
Unfortunately, Canary has been basically gutted by the New 52. I do not know what they were thinking throughout Birds of Prey, taking such a strong, likable character and turning her into a bland pushover with an incredibly tacked-on and uninteresting backstory.
so true i weep for dinah now a days i do hope it gets better with her i mean her and tim have really suffered with the reboot but it's still a young universe i pray her character gets back to where she used to be.
cause no one wants to read a comic about an ugly chick (yes it sounds sexist but it is true) sex sells man. Heck no one questions why every male hero is just ripped as hell and we hardly see them working out.
