Ultraman 80 (ウルトラマン80, Urutoraman Eiti) is the eponymous protagonist of the series, an Ultra Brothers (ウルトラ兄弟, Urutora Kyōdai) candidate from Land of Light who was sent to Earth five years following Ultraman Leo's final fight. Realizing that monster attacks were related to Minus Energy emissions from humans, 80 assumed the form of Takeshi Yamato (矢的 猛, Yamato Takeshi) and worked as a science teacher in Sakuragaoka Middle School to teach children about love and courage. On the first day as a teacher, Takeshi's quick detection of the monster Crescent lead to Ōyama recruiting him into the ranks of UGM after discussing the matters with the principal. From that day on, Takeshi lead a triple life as either a school teacher on weekdays, UGM officer in weekends and as Ultraman 80 when fighting monsters. Unfortunately as the battle against monsters became more intense, Takeshi was forced to quit teaching at Sakuragaoka Middle School and became a full-time UGM member. In the final episodes of his series, he received assistance from his childhood friend Yullian and the two finally return to the Land of Light once the final monster, Margodon, was defeated by UGM themselves. By the time he returned to the Land of Light, 80 was officially recruited as a member of the Ultra Brothers.

Since Takeshi was an Ultraman disguised as a human, he retained his enhanced sense of vision that allowed him to perceive a monster's presence. Takeshi's true form as Ultraman 80 was a secret he obligated to protect, especially during transformations since being discovered by Earthlings would lead to his immediate return to the Land of Light. Using the Bright Stick (ブライトスティック, Buraito Sutikku), Takeshi can either transform into Ultraman 80, expose disguised aliens or summon a barrier which he used against Gymaira. As Ultraman 80, he fights with the use of acrobatic movements and ray beams. His finishing moves are the Succium Beam (サクシウム光線, Sakushiumu Kōsen), Buckle Beam (バックルビーム, Bakkuru Bīmu) and Moonsault Kick (ムーンサルトキック, Mūnsaruto Kikku).

Takeshi Yamato was portrayed by Hatsunori Hasegawa (長谷川 初範, Hasegawa Hatsunori), who received the offer for the role by Tsuburaya's then-producer Kazuho Mitsuda. Hatsunori liked the show's first cour which focused on Takeshi as a teacher and regretted that said plot ended early. Ultraman 80 on the other hand was designed by Osamu Yamaguchi.

Yullian

Yullian (ユリアン, Yurian, 43-50) is the royal princess from the Land of Light, Nebula M78 and Ultraman 80's childhood friend. At some point in the duration of 80's time on Earth, the Land of Light countered the invasion force lead by King Galtan. Yullian went to Earth to personally warn 80 but a chain of events accidentally lead to Emi's death. Since then, she adopted a human form Ryōko Hoshi (星 涼子, Hoshi Ryōko), named by Ōyama and replace Emi to make up her mistakes. Although usually supporting 80, Yamato had her remained as a human and wished to reserve her role as an Ultra in the event of his defeat but she transformed once to help him fight against Pluzuma and Minuzuma. At the end of the episode, Takeshi and Ryōko celebrated their final day on Earth before departing to the Land of Light.

Even in her human form, Ryōko can still use her Princess Ray (プリンセスレイ, Purinsesu Rei) attack and utilize the Medical Gun (メディカルガン, Medikaru Gan) healing pistol. She transforms into Yullian using the Bright Bracelet (ブライトブレスレット, Buraito Buresuretto). As Yullian, she is capable of performing various superhuman feats, but her sole attack was Double Power (ダブルパワー, Daburu Pawā) rotation attack with 80.

Ryōko Hoshi is portrayed by Sayoko Hagiwara (萩原 佐代子, Hagiwara Sayoko).

Minus Energy Monsters

In this series, Takeshi hypothesized that some of the Earth monsters were born from the darkness of human hearts, which he described as Minus Energy (マイナスエネルギー, Mainasu Enerugī).

As revealed in Ultraman Mebius, monsters that are associated with Minus Energy in any capacity are designated as Minus Energy Monsters (マイナスエネルギー怪獣, Mainasu Enerugī Kaijū).

Its abilities are; weeping tears of sulfuric acid from its eyes and exhaling flame from its mouth.
  • Another Hoe was recreated from the Sakuragaoka Middle School's own building's desire to reunite with former first year teacher Takeshi.

Noiseler remain asleep, but UGM and the army's opportunity to strike was foiled when it awakened and marched towards Okajima's rock band. Although the monster meant no harm towards the children, 80 fought against it and lured the monster back to space after it became attracted to his Color Timer's noise. The monster was named after the English word for "noise". Despite the lack of Minus Energy in its debut episode, Noiseler was regarded as a monster of this category from UGM's database in Ultraman Mebius.
