If any of you remember the episode "Do I Hear A Ralts," it focused on Max & Snorunt trying to save a Ralts that was suffering from pneumonia. In fact, Nurse Joy said that if Max brought Ralts to the Pokémon Center an hour later than he did, it would've been too late (hinting that Ralts would've died from pneumonia).
So, rewatching the ending to that episode through the official Pokémon YouTube channel’s video "Top 10 Most Emotional Goodbyes," I got to thinking what an Ice-Ghost type version of the Ralts line would look like. Though I couldn’t dream up any designs, I did figure out what they could be based off of.
Since the Psychic type Ralts seems to be based off a teru teru bozu, a talisman made by Japanese farmers to ward off rainy days, I figure an Ice-Ghost regional variant of Ralts could be based off the yuki onna, a supernatural entity within Japan’s mythology that is usually depicted in white clothes & having dark hair. The yuki onna usually appears on snowy nights and is believed to have ice manipulation, commonly using it on other people.
While the Ice-Ghost type variants for Kirlia & Gardevoir would lean into the yuki onna inspiration further, Gallade (being Gallade) would instead be based off of Boreas, the Greek God of the North Wind. His blade hands would even be changed to resemble Boreas's wings.
So, if you have any designs for these variants of the Ralts line, let me know and drop them in the comments. Also, be sure to let me know what you think of the idea!
