[quote=@The Grey Warden]Anyways, I still need to pick between Green Arrow or Catwoman. Which do you think would have more of an impact on the roleplay? If you want to see the sheet that I did from Catwoman, you can go [url=http://www.roleplayerguild.com/posts/2857096]here[/url]. And judge me on how horrible it looks.

Green Arrow is certainly the more "impactful" choice by virtue of being a potential Justice Leaguer/Avenger. Of course, impactfulness need not be the only metric by which you choose your character. If you'd rather play Selina, I say go for it.
