Hello people, I just made this quick thread to bring up the discussion of Nurse Joy and her..clones? Identical sisters? Idk.
I just made this so the people can discuss the multiple theories as to how the many Nurse Joys were created...
What I can honestly say is that it all falls under the "Ash Coma Theory" which is where all the Nurse Joy look the same because they make him feel safe.
But I think they all look the same because they steal eachother's looks and just want to look like one another, or perhaps, they were just born...perfect. That could be it, but since it's a kids show we're just going to have to assume they look alike just for kicks.
In Kanto, it was stated that the Jenny's were all cousins.
In one of the later anime seasons, there was an episode about a young lass becoming a Nurse Joy (her name wasn't even Joy.)
Just read the Nurse Joy Bulbapedia page.
