I can't help but think that the writers never really liked having Misty in the series. As someone who has watched most of every saga of the series, this is why I think this:
1. Misty was the first classic Kanto character to leave the show permanantly. Ash, Brock and Team Rocket all lasted in the anime for 13+ years (and Brock only just recently left), while Misty was dropped way back in 2002, back when the anime was still at the beginning of its lifecycle. She was officially the shortest-lived classic Kanto character of the series.
2. As we can see now, Misty's departure at the end of Johto was indeed quite permanent. Misty stayed gone permanently for the entire duration of the series and was never allowed back into the main cast in any of the following arcs.
3. Misty's cameos/guest appearances have stopped entirely. The last time Misty had a real appearance in the show was way back in 2005 when Ash came home from the Hoenn league. That was 7 years ago! She appeared in flashbacks in the recent Best Wishes series, but flashbacks don't really count. The writers don't even allow Misty to come back for 2-3 episodes anymore like she did during Hoenn, now she's completely ignored.
4. All the biggest water-related plotlines in the anime happened AFTER she left. Hoenn had Team Aqua which was a villain team all about water. Movie 9 was a blatantly water-themed Pokemon movie with a legendary who was the "prince of the sea." Wallace appears in the DP series as a, "Water Pokemon Master coordinator" and Misty doesn't get to meet him. They gave May blatant water-themed plotlines instead of using Misty for them.
5. Dawn got a Togekiss. Back at the start of the anime, Togepi was exclusively associated with Misty and no other character ever had a Togepi in fillers in the series. Then instead of Misty reuniting with her Togetic, the writers decide to debut Togekiss with Dawn instead.
6. With the current 5th gen anime drawing to a close, this is the second generation in a row where Misty did not get to return. The writers didn't have her appear in a single episode over the entire span of the DP arc, and it looks like she won't appear in the Best Wishes series either.
7. She was probably the worst treated of all the female leads in the series. She barely got much screentime and was always kept on the sidelines while Ash did everything. In many ways May, Dawn and Iris all got bigger roles in their respective sagas than she got, making it seem like Misty wasn't very important.
8. Misty did not get an ending theme in the Japanese version of the anime, while other female leads did.
9. The writers dropped Misty the first opportunity they got, which leads me to believe they might have dropped her at the end of Orange Islands if a female lead from the games existed with G/S instead of Crystal.
10. She's the only female lead with no ongoing rivals, unlike May/Dawn/Iris.
Thoughts on this? It almost felt like they treated her as a placeholder character until they had others to replace her with. Even though both May and Dawn left the show too (and Iris will leave shortly), they all just feel like the writers cared about the way they handled them. Any thoughts?
