Ultraman X (ウルトラマンX(エックス),Urutoraman Ekkusu) is a Japanese tokusatsu drama in Tsuburaya Productions's Ultra Series. It is the 26th series overall. The series started on July 14, 2015.
As Ultra Flares from the sun blanket the Earth, Spark Dolls that had been hidden underground and in the sea are turned into monsters. In order to deal with the sudden outbreak of invading aliens, humanity arms itself with machines of super science and forms the defensive team Xio. 15 years later... A member of Xio, Oozora Daichi, hears a mysterious voice while in combat against a monster. "Unite..." Just as Daichi is on the verge of being obliterated by the creature, he finds himself bathed in a radiant light.
In addition to all the episodes in the series, an end segment of the episodes known as "Daichi's Monster Lab" features Daichi showcasing the Monsters, Aliens, and even Ultras of their respective episodes (as both their Spark Dolls and/or their Cyber Cards to represent them). The segment displayed while tidbits of the Monsters are explained as well as Daichi and X's personal experiences with them.
