Technically, Legacy is Rogue. Even Rogue talks about Legacy as if she as a different person. However, I liked the role that Legacy (or 'Reaper') played in the Age of X. I liked her outfit too. The flashes of green where more impressive than the current green with white X's all over.
It's not that I don't like Rogue... I do! I like Rogue, but it's the little things that made me like Legacy just that little bit more.
Am I alone in this crazy belief? Would anyone like to see Rogue archive the memories of dying heroes to keep their Legacy alive? Perhaps change her outfit? The gloves were exceptionally handy (no pun intended) even if she does have control over her powers now.
I know it's not going to happen, but I would have liked a little more of Legacy to remain after the Age of X had finished.
