I know Death isn't exactly a comic book villain, but I thought this would be interesting.
Anyway, this would be the scenario: After an intense battle, both the X-Men and JLA narrowly survive with their lives. However, having felt "cheated" , a very bitter and vengeful DEATH comes after each and every one of the JLA members and X-Men. This is Death from the movie, "Final Destination", which is shapeless and never really reveals itself.
Questions: Rank from easiest kill for Death to the most difficult (or impossible): Which member of JLA and/or X-Men would Death have the easiest time killing? Which hero or heroines would actually survive the unseen Grim Reaper (and even have a chance of... defeating it?).
