Ultraman 80 (ウルトラマン
The ninth member of the Ultra Brothers, Ultraman 80 comes to earth under the guise of Takeshi Yamato. He becomes a school teacher, but in the first episode also becomes a member of UGM (Utility Government Members).
For the first thirteen episodes Takeshi must keep his identity secret from his students and balance life between his multiple commitments: defending the earth as a member of UGM and as an Ultra, and teaching students going through puberty.
This plot line, however, was dropped later in the series in favour of a more Ultraman-like story focusing on the defence team members exploring various monster-related mysteries. The school and (now grown) students, however, would make an appearance in episode 41 of Ultraman Mebius.
Later in the series Yullian, princess of Nebula M78, shows up to aid 80 in a few of his battles, culminating in a climactic battle against Plazma and Minazma. Shortly afterwards, one final Minus Energy monster appears, named Margodon. 80 and Yullian are prepared to fight it, but are found out by UGM, who insist that they should fight the monster alone. With Margodon defeated by the humans, 80 and Yullian depart for the Land of Light, confident that the planet is safe in the hands of humanity.

Ultraman 80 had average ratings due to tokusatsu not being popular during the time (in the 80's anime was having big fame). 80 is considered among the least known of the Showa era Ultraman Series. In other countries, like France, due to the show being named Ultraman 80, in many promos 80 was named "Ultraman 2080". Tokuriders.com commented that the series are "a little conserved and a little new; it seems the creators had a drought of ideas, and had the imagination with the handbrake on, yet it has points of interest and valuable aspects...". The series currently has a 7.1 rating on the Internet Movie Database.
