I don't know why Japanese fans would be so indifferent to Hypnocatrice, but I hear Lunastra isn't that popular among them since she's seen as essentially being a weaker, more passive Teostra (and thus are indifferent to the idea of her returning), and with one or two exceptions such as Blangonga and Volvidon (are disliked among them, yet managed to return in Generations), monsters who are popular with Japanese players tend to return more often as it adds more hype towards the games.
