Ultraman Cosmos (ウルトラマンコスモス Urutoraman Kosumosu?) is a Japanese tokusatsu TV show being the 17th show in the Ultra Series. Produced by Tsuburaya Productions, Ultraman Cosmos aired from July 7, 2001 to September 28, 2002, with a total of 65 episodes, which currently makes it the longest running Ultra Show to date. Ultraman Cosmos was also the 35th anniversary for the Ultraman series.
In June 2002, Cosmos was taken off of television for several weeks (following the broadcast of the 49th episode) when lead actor Taiyou Sugiura was questioned in an assault and extortion case. When the case against Sugiura was dropped for lack of evidence, Cosmos was put back on the air. TBS and Tsuburaya ultimately pulled five episodes (50, 52, 54, 56, and 58) from broadcast to make up for time lost, and these episodes were later released on DVD.
The series featured many firsts for the franchise, including the start of the story in a movie rather than the series proper. Ultraman Cosmos: The First Contact was the prequel to the series and took place ten years before episode 1. In it, 9-year-old Musashi Haruno encoutners the being of light, Ultraman Cosmos (ウルトラマンコスモス Urutoraman Kosumosu?), and befriends him as the two confront a threat to Earth.
Ten years later, Musashi, now 19 and a member of Team EYES, once again encounters the being of light from his childhood. The dark being Chaos Header has appeared and is corrupting the monsters of Earth, making them become ravenous and violent creatures that threaten humanity. Through Musashi's will to see the beasts and humans live in peace, Cosmos grants him a new power that will allow him to heal the corrupted creatures.
Team Elite Young Expert Squadrons, also known as Team EYES, is the science investigation team of the series. The aim of the operation is not to destroy monsters, but rather to find a place where they can live peacefully on earth. Once a monster is healed by Cosmos, members will transport it to a conservation area where they may live peacefully without the threat of humans or the Chaos Header.
A 19-year-old pilot candidate part of the SRC Space Development Center. Musashi first encountered Ultraman Cosmos as a child and formed a bond with him that would return to aid him as an adult. He confronts a monster corrupted by the Chaos Header's Virus of Light (光のウィルス Hikari no Wirusu?) and is allowed to join Team EYES as a result of his brave actions. Musashi faces a dilemma later on in the series when he realizes that the Chaos Header is not simply a virus, but a living creature that he must destroy.
Hiura is the 33-year-old captain of Team EYES and one of the founding members of the SRC research project. He is affectionately called "cap" by his teammates and was the reason Musashi was allowed to team EYES. Though essentially a gentleman, Hiura has a wild side that comes out when he finds himself in battle.
The vice-captain of Team EYES, 28 years old. Mizuki is one of the original defense instructors and joined Team EYES after sympathizing with their policies and ideals. While she is generally reserved, she often takes the lead in battle and guides her team through dangerous situations with great care and experience.
A 23-year-old former police officer and the rookie member of EYES before Musashi. He has a cool, yet slightly aggressive personality that SRC initially did not want on their Team EYES project. He often comes into conflict with other members on how to deal with the corrupted monsters, especially butting heads with Musashi many times. The two form a deep friendship throughout the series as Fubuki comes to understand Musashi and his feelings towards life. Though Fubuki is strong, he was a sick child who was unable to defend those closest to him; this led to him wanting to become strong to protect others, an ideal which was eventually washed away by a need to simply be strong.
In Ultraman Cosmos vs. Ultraman Justice: The Final Battle. the final entry into the series taking place three years after the final episode, Fubuki has become the captain of a new batch of Team EYES members and fights with the ideals of Musashi in mind.
Koji is the 25-year-old mechanic of Team EYES and seen as the most naive member of the team. He hails from Kochi prefecture, his teammates often think of him as a country boy because of this. He was called a genius scientist at a young age and was watched closely by the SRC project. Koji joined the team so he could escape his father, a man who he shares an uneasy relationship with.
A 19-year-old member of the team and the youngest member, younger than Musashi by 10 months. Ayano is very spirited and often spoiled due to her upbringing. She has a habit of falling in love with handsome men and doesn't concern herself with femininity. She was initially very cold towards Musashi, unable to accept that her junior on the team was actually older than she was and often referred to him as "Member Musashi" throughout most of the series. The two seem to form a close bond as the series plays out, Ayano eventually on a first-name basis with Musashi by the end of the show.
The being of light that comes from space in the series and hopes to establish peace in the universe. He sparks a friendship with the young Musashi that will be a lifelong bond between the two. After defeating the threat in First Contact, Cosmos returns to space and is not seen again for ten years, in which time much has changed on earth.
Musashi becomes Cosmos by using the Cosmo Pluck (コスモプラック Kosumo Purakku?) and shouting "Cosmos!". Cosmos' default form is the blue Luna Mode (ルナモード Runa Mōdo?) used to heal monsters under the influence of Chaos Header's virus. The red Corona Mode (コロナモード Korona Mōdo?) is the mode that Cosmos uses when he must kill a monster. In addition to these Cosmos also has Eclipse Mode (エクリプスモード Ekuripusu Mōdo?), for dealing with especially strong monsters or Chaos Ultraman. The Eclipse Mode is also a special mode that can only be sustained for one minute at a time and the golden Miracluna Mode (ミラクルナモード Mirakuruna Mōdo?) which appears in the final episode and serves as an upgrade to Luna Mode. He also has the Space Corona Mode (スペースコロナモード Supēsu Korona Mōdo?) and the Future Mode (フューチャーモード Fyūchā Mōdo?) but these forms were never shown in the series. They are only shown in Ultraman Cosmos vs. Ultraman Justice: The Final Battle. He also has the Phantom Corona Mode (ファントムコロナモード Fantomu Korona Mōdo?), but it only appears in Ultraman Cosmos 2: The Blue Planet as Musashi's vision.
