Electric Soldier Porygon: "Dennō Senshi Porygon" (でんのうせんしポリゴン ,Dennō Senshi Porigon?, literally "Computer Soldier Porygon", although most commonly translated as "Electric Soldier Porygon") is the thirty-eighth episode of the Pokémon anime's first season. It was first broadcast in Japan on December 16, 1997, and has since not aired anywhere else. In the episode, Ash and his vrienden find at the local Pokémon Center that there is something wrong with the Poké Ball transmitting device. To find out what's wrong, they must go inside the machine.

The episode is infamous for using visual effects that caused seizures in a number of Japanese viewers, an incident referred to as the "Pokémon Shock" (ポケモンショック ,Pokémon Shokku?) door the Japanese press. Six hundred eighty-five viewers were taken to hospitals, but only two people remained hospitalized for meer than two weeks. Due to this, the episode has been banned worldwide.

After the shock, the Pokémon anime went into a four maand hiatus, and it returned on TV Tokyo in April 1998. Since then, the episode has been parodied and referenced in cultural media, including an episode of The Simpsons where the Simpsons go on vacation to Japan and watch a cartoon called Battling Seizure Robots, resulting in the entire family going into convulsions. In a South Park episode, Kenny McCormick suffers from a seizure after playing a videogame called "Chinpokomon". Because of this Porygon2 and Porygon-Z have never appeared in the anime door a bad flash. This is in the Guiness World Records in the Most seizures caused door a TV program. This is a big history to Pokemon anime.

Holiday Hi-Jynx
This episode is from the Indigo League series of the original Pokémon series. This episode is the first to feature a new Pokémon called Jynx, which resembles, according to sources, an African-American female, with long blonde hair, and big lips (it had big lips due to one of its attacks being a "kiss" attack). The episode "Holiday Hi-Jynx" aired on Kids WB!, and not everyone was happy with the new Pokemon.

A woman named Carole B. Weatherford wrote an artikel about Jynx, saying it was racist to African-American people, and soon after, the episode was removed from rotation. Also, this caused other episodes involved with Jynx to be banned. Nintendo ended up changing Jynx to purple to keep the racism rumors down. Even though they changed Jynx, future episodes ended up tonen Jynx as it is, and episodes which has Jynx as a main character are usually banned. One of those known episodes is "Kōri no Dōkutsu!", known meer commonly as "The Ice Cave". The episode was part of the Master Quest series, originally as episode 252, but was banned due to its heavy focus on Jynx. Brock gets sick while in an ice cave, and is taken to a Pokémon Center in the cave, and instead of Chansey as nurses, Nurse Joy has a Jynx, which plays a main role in the episode, and Jynx, instead of being purple, has the same black face as it did in "Holiday Hi-Jynx", thus causing its ban after its first, and only, air. The episode was never seen outside of Asia except Brazil. There was an English dub made door 4-Kids Entertainment, but wasn't aired after the ban.

Banned in the U.S. after september 11
"Tentacool and Tentacruel"
The first episode to be banned after the September 11 attacks, mainly because the censors noted similarities between the attacks and the Tentacruel attacking the city. The character Nastina also used large-bore assault weapons during the fight scenes in the episode. However, Tentacruel striking a building was not removed from the opening theme, and the episode is still readily available on the home pagina video and DVD markets. This episode also aired on Cartoon Network at least once.

"The Tower of Terror"
This episode was the seconde to have a 9/11-related banning, this time due to name rather than actual content. However, this episode is no longer banned and continues to air around the world.

"A Scare in the Air"
This was the third episode to be banned after September 11, 2001, as well as the seconde to be banned on the basis of the 9/11 name. In response, 4Kids Entertainment temporarily renamed the episode "Spirits in the Sky" to get around the ban. The episode's original titel has since been restored.
