Gonin sorotte note "The five people assembled"... Goranger!Himitsu Sentai Goranger (Secret Squadron Goranger) was the first entry in the Super Sentai franchise (although it and its direct successor J.A.K.Q. Dengekitai were simply recognized as the plain "Sentai Series" until years later) , airing from 1975 to 1977, lasting 84 episodes and a movie (longer than any of its successors).The evil terrorist group known as the Black Cross Army is threatening the world, so the Earth Guard League (EAGLE) is set up to defend it. The Black Cross Army destroys EAGLE's bases in Japan, but five secret agents survive, using superpowered battle suits to become Goranger, and take revenge against the forces of evil.
Tsuyoshi Kaijō / Aka Ranger: The Leader. A master tactician and soccer player.
Akira Shinmei / Ao Ranger: The Lancer. A cowboy and marksmanship instructor.
Colorful Theme Naming: The codenames used each member's respective color as the head word and the word "Ranger"/"Renger" as the tail. Unlike the majority of Sentai shows from Denziman and onward, the codenames used the Japanese names for the colors instead of English ones (i.e. "Aka" instead of "Red").
Cool Airship: The Variblune, which is destroyed in #42 and replaced by the Varidorin during the same episode.
Cool Bike: The Goranger Machines, which consist of one solo bike for Tsuyoshi (the Red Machine) and two sidecar-equipped bikes for the rest of the team (Akira's Blue Machine and Kenji's Green Machine, which are shared with Daita and Peggy respectively). The Goranger Machines are later destroyed and replaced with the Star Machines, which also consisted of one solo bike (the Red Star) and two sidecar bikes (the Blue Star and the Green Star).
Eye Catch: Goranger's eyecatch features illustrations of the Goranger team.
Genius Bruiser: Daita Ooiwa, a master of judo and skilled mathematician.
He has a yellow "V" shape across his chest, while those of his teammates (the amount depending on their number) are colored red (although red stripes wouldn't show up on his suit).
A gold "1" is placed atop his visor with eagle wings coming off from it. These wings are lacked by the other Goranger's, with the color of the number being silver for the other men and red for Momo Ranger.
His collar is much taller than the other four.
While Akira, Daita, and Kenji have black visors, Tsuyoshi has a blue visor, while Peggy's is red.
He wears white boots and gloves, this is shared by Peggy, while the other men have black boots and gloves.
Mid-Season Upgrade: Episode 43 in particular, which is focused on showing the team's new powers, weapons and vehicles (including a new finishing move).
Elite Mooks: The Black Cross Army Stealth Corps (featured in Episode 64 and onward).
Praetorian Guard: Golden Mask has two imperial guards who are always on his side.
Mook Mobile: The Condolas, aircraft that assaulted the Gorangers.
The Movie: Five of them; but the first three and the fifth were just theatrical showings of select TV episodes (specifically 6, 15, 36 and 54). Only the fourth one, "Bomb Hurricane," was an all-new work and it takes place during Daigorō's brief tenure on the team.
The Smurfette Principle: Peggy, who not only wears pink, but has a red valentine heart-shaped visor on her helmet and uses the earrings on her helmet as small grenades. However, the Gorangers are assisted by a secret agent named Yōko Katō, who serves as the show's second heroine. Yōko even wears the Momo Ranger suit in two different episodes.
"Super Sentai" Stance: Surprisingly the stance in the lead image isn't used until very late in the series.
Supervillain Lair: The Black Cross Castle. It's later learned the Fuhrer is actually a part of the castle itself.
Big Eater: Ōiwa Daita orders four extra large bowls of curry in the first episode.
Commander Edogawa tells him that their "large" bowls are massive, and tries to convince him to have two. Daita insists on having four. When they are served up, they are indeed massive.
"Blind Idiot" Translation: The team's name is meant to be "Goranger" (as in "Five Rangers"), but it's spelled "Gorenger" on their bikes (as well as on Commander Edogawa's patch and the flags on their Star Machines). This misspelling is still used by the official merchandise as an artifact from this mistake.
And since Wikipedia has strict rules about citing references, "Gorenger" being on the merch makes this the series' name on that site, even if nobody's really happy with it. This extends to the Rangers themselves (becoming Akarenger, Momorenger, etc.)
The Chew Toy: Daita seems to be the team member who most often has the bad luck in the team.
Chuck Cunningham Syndrome: At the start of the series, Commander Edogawa is assisted by three female secret agents who help out the Rangers. Their names are Yōko Katō (007), Tomoko Hayashi (008) and Haruko Nakamura (009). After several episodes, Tomoko and Haruko stop showing up completely and only Yōko remains as a regular character.
Improbable Weapon User: The Gorangers fight with standard weapons, but when it comes time to finish of the monster, they summon a mighty... soccer ball. Which somehow causes the enemy to explode by beaning him in the head.
Later on, they use the Goranger Hurricane: an American football with fins on it, which rather than exploding turns into whatever the villains fear or are weak against. More recent fans will probably remember it as the move that turned into a garbage truck in Kaizoku Sentai Gokaiger's first episode. As homage, Ressha Sentai Tokkyuger's team cannon does the same thing.
Kiai: The Zolders shout out a distinctive "hoi" whenever they attack their victims.
Redshirt Army: If you are a member of EAGLE but are not a Goranger, YOU WILL DIE. This kicks off on day one, with each Goranger-to-be being the sole survivor of his or her respective base, which is indeed what leads to them being made the Gorangers.
Spell My Name with an S: The official spelling varies between "Goranger" or "Gorenger" depending on the merchandising (most products tend to favor "Gorenger" though).
Theme Naming: The first syllable of each of the original rangers' family name note or in Peggy's case, her given name, since her full name is always written in the western order, even in Japanese. form the name "Kashiopea", as in "Cassiopeia".
Tonight Someone Dies: Daigorō Kumano's final episode was titled "Crimson Special Attack!! Yellow Ranger Dies at Sunset".
Too Dumb to Live: One victim of the week. If you're being chased by a pink telephone monster, and as soon as you think you've ditched it you notice a giant pink telephone... you probably shouldn't use it to make a call.
