I remember when DP first started, Dawn was paired almost immediately with every early DP character. She was paired with Ash, Paul, Zoey and Gary right at the start. Later on there was Conway, May, and Barry. People seemed to pair Dawn up with these 7 characters in a heartbeat.
Iris has now existed for 40 episodes (in Japan at least), which is actually a lot of time. In that time, there is the usual pairing with Ash, although for some reason Negaishipping doesn't seem to have that big support that Advance and Pearlshipping had early on. Otherwise people pair Iris with Cilan, which reminds me of Gymshipping (Misty/Brock), from the early seasons.
Why isn't Iris paired with more characters? Do you think people feel Iris is less shippable, since she's a bit more unusual as to what we'd expect for a female protagonist?
