Carole Boston Weatherford, a cultural critic, claimed that Jynx, which appeared in Holiday Hi-Jynx, was a negative racial stereotype of African-Americans in an article titled "Politically Incorrect Pokémon" on the magazine Black World Today. She chiefly compared Jynx to the racist characters in The Story of Little Black Sambo, and further compared Jynx to Mr. Popo of the Dragon Ball franchise, a character who is also potentially offensive in his design.
Weatherford's complaint caused many repercussions in the Pokémon franchise. The sprites of Jynx in the Western releases of Pokémon Gold, Silver, and Crystal were edited, and EP250 was cut from international airings of the anime. A sequence depicting Jynx in its original design in All Things Bright and Beautifly! was also cut from the dub. Jynx's design was officially revised by Game Freak to be purple rather than black, and this change was reflected in later core series games, including in Japan and South Korea, beginning with Pokémon Ruby and Sapphire, and in the anime starting in Mean With Envy. Jynx has also been recolored in VIZ Media's reissues of Pokémon Adventures. Although the manga is colored in black-and-white, Jynx appearing in the manga are recolored as a dark gray rather than a straight black, suggesting that they are purple instead of black. It is also recolored to purple on the back cover of the reissue of Volume 4. The Virtual Console versions of Pokémon Snap and Pokémon Trading Card Game also recolor Jynx's face.
In recent years, some fans of Pokémon have noted that Jynx may be inspired by ganguro, a Japanese fashion where women tan heavily, bleach their hair, and apply large amounts of makeup, instead of a black stereotype. This theory is mainly based on Jynx's long, straight, blonde hair, a common attribute of ganguro fashion. Another theory is that Jynx is based on a Nordic princess as per the legends saying things like due to the blistering cold, a princess's skin turned black. They argue that Jynx's hair looks more like royalty than an African stereotype. They also say that being based on a Viking could reason why they are Ice type. This is further expressed by Jynx sharing traits with the iconic opera singing "Fat Lady," who is pop-culturally portrayed dressed as the valkyrie Brünnhilde.
