OK, but you have to remember, in most cases (current case excluded because of the obvious) CaptainsOriginally posted by: DDBen
Rukia in the first episode was at her full power up until she gave her powers to Ichigo. As we have seen in many of the captain and vice captain battles and to a lesser extent with those in the 11th the wounds she recieved should not have been able to hurt her to the extent of being unable to fight at all IF she was always this powerful.
and Vice-Captains and other powerful Shigami have thier power reduced when they go to earth. Just
because she was that weak on Earth doesn't mean she wasnt powerful in her own right in Soul Socity.
