UUltraman Cosmos (ウルトラマンコスモス ,Urutoraman Kosumosu?) is a Japanese tokusatsu TV show being the 18th show in the Ultra Series. Produced by Tsuburaya Productions, Ultraman Cosmos was aired between July 7, 2001 to July 20, 2002, with a total of 65 episodes, which currently makes it the longest running Ultra Show to date Utraman Cosmos                                                           

A kinder, gentler Ultra hero was released in the summer of 2001 to coincide with the 35th anniversary of the original Ultraman. The launch of the TV show is quickly followed by a feature film prequel, and is the first time for an Ultra movie and TV series to be so closely linked. Following recent trends, Cosmos is another type-changing Ultraman, with the all-blue Luna and asymmetrical red and blue Corona modes. The modes represent a "gentle" side and a "strong" side, respectively. Later in the series, Cosmos also develops the "courageous" Eclipse mode, with a symmetrical blue, red, and gold design. The series was extended to 65 episodes, which makes it the longest-running in the franchise to date, although it was briefly canceled due to the arrest of the main actor for a crime he did not commit.
This series is preceded by the feature film Ultraman Cosmos: The First Contact. The TV series takes place eight years after the events in the movie, when monsters are once again plaguing humanity. Now Musashi is a 19-year-old young man. He joins a wing of SRC known as Team EYES. Musashi encounters Cosmos again, and the two merge to defend the Earth.
The recurring villain in this series is the Chaos Header, a virus that either infects monsters or replicates them, creating a more violent and aggressive version. Lidoriass, Golmédé, Clevergon, and even Ultraman Cosmos himself. Usually, you can distinguish the original monster from the infected monster because the infected one has "Chaos" as a prefix in its name and has a head with a lot more junk on it, and has a power boost. This series has a lot of monsters that pay homage to monsters from the past. The Baltans are the most blatant example. Golmédé and Lidoriass are similar to Gomess and Litra in episode 1 of Ultra Q. There is also Supittol (with head-covering armored petals around his neck like Gabora of Ultraman episode 9), Gigi (with distinct black and white lines and three faces like Dada of Ultraman episode 28), Mudon (like Seebozu) and Mienin and Gamoran (like the perennial favorites, Pigmon and Garamon, respectively).
This series is followed by the feature film, Ultraman Cosmos: The Blue Planet, in which Cosmos gains a couple of new modes (Space Corona and Phantom Corona). This in turn is followed by Ultraman Cosmos vs Ultraman Justice: The Final Battle.
