Ultraman Mebius is a Japanese television series produced by Tsuburaya Productions and Chubu-Nippon Broadcasting. It is the 17th TV series and 40th anniversary production in the Ultra Series, which first began in 1966. It premiered on the Tokyo Broadcasting System on April 8, 2006. Unlike the two prior entries, Ultraman Nexus and Ultraman Max, Mebius was moved from Saturday mornings to Saturday evenings at 05:30. "Mebius" is the Japanese approximation of Möbius; the Möbius strip is a recurring motif in the series and the show going to air in Korea in April 2012. The series opens with the introduction of the rookie Ultraman Mebius, who is sent to Earth by the Father of Ultra. The series is set 40 years after the shows of Ultraman, and makes many references from Ultra Q through to Ultraman 80.

The continuing adventures of Matsuzaki, a racing tipster for a sports paper. Matsuzaki befriends a mysterious old track bettor named Tokudaiji. The man turns out to be a well-connected millionaire and invites Matsuzaki to his home.

In the near future, the economy has collapsed and the country has turned into a ghetto. A secret agency, Gokuraku, has been created by the government. Secret agents Aya and Chinatsu's mission is to fight against one of the largest international companies, Kuroda Group. Secret agents are called 'Lady Ninja', and they use a traditional Japanese umbrella-like tool called 'sangoku' to defeat evil.

Doctors Kazamatsuri and Onizuka are geneticists researching cures on diseases such as AIDS and cancer by performing experiments to strengthen the human body. The test subject is Shin Kazamatsuri, motorcycle racer son of Doctor Kazamatsuri. Unknown to them, their operation is funded by a syndicate group, who plan to use this research to have the bodies of men strengthened for their own gain—they have already been experimenting in the field of cyborg soldiers, to a less-than-successful attempt. However, they did not count on Onizuka's own secret ambitions; the mad Onizuka wanted to create a new species, by fusing a grasshopper's DNA with the test subject's, in order to start a new civilization and be their god. He has tested on himself, but seems to be having greater success with Shin.

The first of a 2-part sequel to the 2006 TV Series Ultraman Mebius. After the death of Alien Empera, the sentient being known as Armored Darkness is activated to carry out the Emperor's Plan B. To make its presence known, Armored Darkness revives the monsters Saramandora, Roberuga, Mukadender, and Cherubim.

While the Subordinate weeped, Mirai informed him that Ryu was alive, saved by the power of Ultraman King. He revealed that after Alien Emperor's defeat, Armored Darkness had been known for some time and Ultraman Hikari was sent by Ultraman King to destroy it before it could reach Earth, but the Armor's strength overpowered him and possessed him.
