At this point I kinda don't want Nintendo to ever bring her back. Not because I hate Krystal or anything but rather because of the state of the industry RN... I'm worried that if they bring her back they may change not only her personality but her design too and she's already perfect as she is.
Plus, Nintendo Fans are still very woke-minded and if the Company ever brings Crystal again without changes, the fans may accuse her of being "sexualized gooner material" or some crap like that and that prompt Nintendo to bury her once again.
