Pokemon has changed a lot over the course of the franchise, and that includes the art style. Several artists have worked on Pokemon since its start, leading to changes in how the artwork and actual Pokemon look. While plenty of newer Pokemon are loved, many fans are nostalgic for the older style of artwork.

Pokemon fans have been enthusiastic about both the watercolor designs and the pixel representations of the Pokemon, resulting in the post earning over 10,000 upvotes.

The same artist previously shared Ken Sugimori-styled versions of Sprigatito, Fuecoco, and Quaxly, as well as artwork of the mysterious Mimikyu. Pokemon fans were similarly enthusiastic about those designs.
Of course, not everyone wants to go back to the way that the Pokemon games used to be. Some refer to those who are overly enthusiastic about the Pokemon series' roots as "Genwunners." Still, even those who aren't necessarily sold on the Gen 1 art style often share criticism of the series' tendency in recent releases to turn starter Pokemon into bipedal creatures as they evolve. With mere months left until the original games Pokemon Red and Green turn 30 years old, there's no real to satisfy every fan who has ever enjoyed a Pokemon game. Given the franchise's ongoing popularity, though, it seems that most are pretty happy with its
