List of The Ultraman characters

This is a character list for the 1979 anime The Ultraman, a joint collaboration of Tsuburaya Production's Ultra Series with the anime studio Sunrise. In contrast to the Showa Era Ultra Series (from Ultra Q to Ultraman Leo), The Ultraman took place in an alternate universe wherein the main Ultraman Jonias was the first to arrive on Earth, as well as his point of origin not being Land of Light in M78, but rather the planet Ultra U-40.

Earth Defense Army

The Earth Defense Army (地球防衛軍, Chikyū Bōei-gun) is a United Nations organization established for the purpose of Earth's defense, space development and observations around the world. There are bases located in the United States, Europe, Africa, and the Far East. Each branch had its own group of Science Defense Squad (科学警備隊, Kagaku Keibitai), abbreviated as SDS, an elite squad of soldiers and scientists formed in the wake of mysterious phenomenon across the globe.

Science Defense Squad

The series focuses mainly on the Far East branch of the SDS; the Earth Defense Army members led by Captain Akiyama, who later on was promoted in episode 26 with Gondo replacing him in episode 28. In the event of Empire of Heller's full-scale invasion on Earth, the SDS disobey orders from Earth and joined the U-40 Fleet to attack the Titan Base and made their invasion on Heller City of U-40. During their raid on the main tower, they were captured and almost executed by Mac Datar before Jonias interfered while Pig released them from their restrains.

He had a great intuition towards a monster's movements, such as being able to predict Gamiba's presence on Maroi Island after knowing such place had no record of earthquake by natural means but is also fearful of supernatural existence (such as the rumored sightings of Yuki-onna).

Ultra People

In The Ultraman, the Ultra People (ウルトラ人, Urutora-jin) are human-like residents of planet Ultra U-40 (ウルトラの星U40（ユーフォーティー）, Urutora no Hoshi Yū Fōtī), demonstrating a similar culture to Ancient Greece, wearing garments such as the Himation and Toga. Despite their initially primitive appearance, they possess advance science and technology, with an underground city which was hidden beneath the planet's surface.

A long time ago, the citizens of U-40 were human-like beings who wished to expand their race further to the outer space. Earth was one of the stars they visited and established the very first human civilization with Neanderthals. To combat against the evil forces in space, they created the Ultra-mind (ウルトラマインド, Urutora Maindo) and became Ultra-Humanoids (ウルトラヒューマノイド, Urutora Hyūmanoido). They would soon discard the Ultra-mind within a black hole to prevent any misuse from outside forces.

When the Earth was plagued by mysterious phenomenon, the Ultras sent their message and strongest warrior Jonias to guard the planet from monster attacks. One of these nefarious forces, called the Badel People invaded U-40 as their Devil Spirits were acting on Earth. With Jonias still in recuperation, Elec, Loto and the other five warriors would fight the invading forces while Hikari and Amia tried to invade the Badel Star. A fully healed Jonias participated in the battle again to save his kind while the other seven warriors contain the stolen Ultra-mind. However, not long after that, the Empire of Heller, a renegade faction of the Ultra People, invaded the U-40 in retaliation of their banishment in the past. The surviving Ultra People were led by Elec and Loto as the U-Fleet (U（ウルトラ）艦隊, Urutora Kantai, the "U" stands for "Ultra"), with the SDS joined them in a campaign to reclaim U-40. With the Empire of Heller defeated and Heller killed, U-40 citizens that previously scattered in outer space returned to their home world and celebrated Jonias's victory.

Although still in human size, eight chosen warriors of U-40 have Star Symbols (スターシンボル, Sutā Shinboru) on their chest allowing them to change their sizes into giants and travel to any planets in short distances and measure their energy levels. As the Earth's atmosphere quickly drains their energies, they can only sustain their giant forms for 4 minutes as the Star Symbol changes color from blue to yellow, and finally to red after 30 seconds. When bonded with an Earthling or to transform into giant sizes, they used the beam-Flasher (ビームフラッシャー, Bīmu Furasshā), a star-like pendant by placing it on their forehead to transform. Starting from episode 20, later appearances had the transformation style added with the phrase "Ultrachange!" (ウルトラチェンジ!, Urutora Chenji!). According to Elec and Loto, regular people of U-40 can submit themselves into suspended animation to survive for a longer period, though this required the Ultra-mind to reverse the process altogether.

During Badel's invasion on Earth and U-40, Jonias and Hikari lost their lives in the ensuing battle and were carried to his home world for recuperation. The recently healed Jonias bonded with Hikari once more to reverse the tide of the battle, therefore saving both their planets. During the U-40's Fleet's raid on Heller City, Jonias separated with Hikari to join his brethren in space in fighting against Empire of Heller's combat ships. Once his deed was done, he would fuse with the youth in one final time to save the SDS and Amia. Once peace has returned to Earth, Jonias revealed his human form to Hikari as he and Amia stayed on Earth to help repair the damages done from the ensuing war. Months later, the two bid farewell to the SDS but promised to return should Earth's safety be threatened again.
