The Dark Side of Pokémon: 30 Years of Controversies You Never Knew About

Pokémon, celebrating its 30th anniversary, has evolved from a video game into a global phenomenon, attracting a diverse fandom from children to collectors. Despite its widespread success, the franchise has faced numerous controversies throughout its history, ranging from public outrage to bizarre incidents and unintentional involvement in unusual headlines. One of the earliest and most infamous incidents occurred on December 16, 1997, when the 38th episode of the Pokémon anime, "Dennō Senshi Porygon," aired in Japan. The episode featured rapid red and blue flashing lights, an animation technique called "paka paka," to depict explosions in cyberspace. This strobing effect triggered widespread reports of headaches, dizziness, nausea, and even seizures and unconsciousness in 685 individuals, with two remaining hospitalized for two weeks. This incident garnered significant media attention and caused Nintendo's stock prices to dip. Former company president Hiroshi Yamauchi clarified that the Game Boy games were not responsible, as they were black and white and unlit. Despite this, Pokémon continued its journey to the US, albeit with a slight rebranding from "Pocket Monsters" to avoid confusion with the "Monster in My Pocket" toy line. Upon its US release in September 1998, Pokémon Red and Blue for the Game Boy capitalized on growing interest in Japanese pop culture. While the games themselves were largely harmless, they spawned numerous urban legends and rumors. The existence of the 151st Pokémon, Mew, was a subject of intense schoolyard debate, with many players resorting to glitches or cheating devices like Game Sharks to acquire it, often at the risk of corrupting their save files. Another beloved glitch was "MissingNo.," a garbled blob of pixels that could duplicate items. These in-game secrets fueled speculation about other hidden Pokémon like "Mewthree" or "PikaBlue," the latter of which eventually appeared as Marill in the second generation of games. A more morbid urban legend, the "Lavender Town Syndrome," emerged in the early 2010s, claiming the background music of Lavender Town in the original Japanese games caused a surge of suicides and illnesses in children. This was later debunked as a creepypasta, but its effectiveness stemmed from its proximity to real-life concerns surrounding Pokémon's impact on children. In December 1999, during the peak of "Pokémania," a Burger King promotion offering 57 collectible Pokémon toys with kids' meals led to unforeseen tragedy. The Pokeball-shaped containers for the toys were later found to be a choking hazard, as the red half could form an airtight seal over a small child's nose and mouth. This resulted in the tragic death of a 13-month-old in California and a near-identical incident in Kansas, prompting Burger King to issue a recall and apologize publicly. The localization of Pokémon media for Western audiences also involved significant changes to ensure it was kid-friendly. Four Kids Entertainment, responsible for dubbing the anime, made efforts to de-Japanize content, renaming characters and translating or removing Japanese text. Infamously, "onigiri" were referred to as "jelly donuts." Several episodes were banned entirely, including "Beauty and the Beach" due to fan service and an unedited version featuring adult men gawking at Misty, and another episode featuring excessive gun usage in the Safari Zone, which led to continuity errors. One Pokémon, Jynx, faced criticism for its design, which was perceived as evoking racist stereotypes (resembling blackface) and exaggerated feminine features. Despite speculation about its Japanese folklore origins, Jynx's black complexion was eventually recolored to purple across all media. Even later, a 2018 episode of the Sun and Moon anime featuring Ash Ketchum in brownface paint to blend in with a local population was not aired in the US. Early Pokémon manga also underwent significant cleanup, with much more violent battles and risque depictions of female characters, likely due to the artist Toshiro Ono's background as a hentai artist. The Pokémon Trading Card Game (TCG) also attracted scrutiny, with its collectible nature drawing comparisons to gambling. This led to bans in various places, including some schools and Saudi Arabia. Beyond competitive bans, some Japanese card designs required drastic changes for Western release. Examples include the "Grimer" card's suggestive line of sight, "Misty's Tears" depicting her seemingly nude, slot machines being replaced with generic arcade games, and Koga's Ninja Trick, which originally featured a "manji" symbol (a common Asian religious symbol) that resembled the Nazi swastika. Religious imagery in Pokémon, often tied to Japanese Shintoism, also sparked controversy. Some conservative groups labeled the monsters as "pagan demons." More bizarrely, Christian imagery appeared, such as Gengar in a graveyard with cruciform headstones (secularized for Western release) and Misty brandishing a cross in the anime, raising theological questions about the existence of Christianity in the Pokémon universe. The "satanic panic" surrounding Pokémon in the late 1990s, fueled by its monster-befriending and pro-evolution themes, even prompted the Vatican to issue a formal statement in 2000. Pope John Paul II blessed the franchise, praising its "inventive imagination" and "ties of intense friendship." In 2025, a fan even gifted Pope Leo a Pokémon card, which he allegedly found amusing, highlighting Pokémon's unusual acknowledgment by the Vatican on multiple occasions. The introduction of Pokémon Go in 2016 marked a significant evolution for the franchise, becoming a cultural phenomenon that surpassed its initial craze. The augmented reality mobile game encouraged players to explore the real world to catch virtual Pokémon, promoting exercise and social interaction. However, it also led to negative incidents. Criminals exploited isolated PokéStops to rob unsuspecting players, and reports of accidents and casualties linked to distracted gameplay while walking or driving became common. Two LAPD officers were even fired for failing to respond to an armed robbery call because they were trying to catch a Snorlax. Pokémon Go also became a topic in the 2016 US presidential election, with Hillary Clinton and Donald Trump both referencing it. Concerns about the game's use of GPS data and smartphone cameras led to its ban or restriction in several countries, including China and Iran, due to surveillance fears. Further concerns arose when Niantic, Pokémon Go's developer, was acquired by a subsidiary of Saudi Arabia's Public Investment Fund, a country where Pokémon has been banned for resembling gambling and promoting non-Islamic values. Financially, Pokémon is the biggest media franchise globally, generating over $100 billion across various sectors. The secondary market for Pokémon cards has transformed from a hobby into a serious investment opportunity, with a 574% increase in sales on eBay between 2019 and 2020. The perceived value of cards is influenced by rarity, competitive utility, and official rule changes, attracting speculators. The "blind bagged" nature of booster packs creates a market where sealed products are highly valued for the element of surprise. In 2022, YouTuber Logan Paul set a Guinness World Record by acquiring a PSA Grade 10 Pikachu Illustrator card for $4 million, which he later resold for $16.5 million in 2026. This highlights how the history and unique circumstances surrounding an item can drastically increase its value, similar to Nicholas Cage's Action Comics #1 or the Mona Lisa. This immense value has also led to a spike in high-profile Pokémon card thefts, with incidents like a $180,000 heist in Anaheim and an armed robbery in New York City occurring in Pokémon's 30th anniversary year. Despite these controversies, Pokémon's popularity has never truly waned, with new generations of monsters introduced every three years, maintaining a cycle of attracting new players and re-engaging old ones. While some hardcore fans criticize Game Freak's incremental improvements to the games, arguing for more innovation, the franchise's simplicity and familiarity are also seen as key to its enduring appeal and accessibility. The vast "waves" generated by Pokémon, whether controversial or bizarre, underscore its unprecedented popularity and significant place in society.
