She's not had tons of individual development, but she's been ok in the titles in which her appeared. It just bothers me that some fans make it seem like there was this concerted effort to push Monica aside so that Carol could be promoted and that's not quite how it happened. Carol was still Binary and still in semi limbo herself in the mid 90's, when Monica was kinda marginalized. It was Genis who took the CM mantle from Monica and then took her Photon name! But for whatever reason Carol is the character people choose to resent.
