== Plot ==
{{See also|List of Mazinger characters#From Grendizer|l1=List of Grendizer characters}}
The Vega homeworld has become unstable due to the exploiting of Vegatron, a powerful radioactive ore. Seeking to expand his militaristic empire and find a substitute planet to settle upon, the ruthless [[King Vega]] unleashes his armies—composed of flying saucers and giant robotic monsters—and turns first against neighbors such as Fleed, a highly advanced but peaceful world. The once verdant, idyllic Fleed is turned into a radioactive wasteland. Too late, the only known survivor of the royal family, the Crown Prince [[Duke Fleed]], manages to steal the Grendizer, the robotic embodiment of the Fleedian God of War, from the Vegan invaders who plan to use it to spearhead their invasion fleet. Grendizer is a giant monster robot that interfaces with Spacer (Spaizer), a flying saucer that enables the robot to fly.

Fleeing Vegan space by flying at [[faster-than-light|faster than light]] speed, the Duke enters the [[Solar System]] and switches course to Earth, making a rough landing in Japan, on the slopes of [[Mount Fuji]]. He is befriended by Doctor Umon, a noted scientist who oversees a research laboratory called the Space Science Lab near a small [[ranch]]. The kindly Umon takes in the young humanoid alien as his son, under the assumed name of Daisuke, and assists him in hiding Grendizer. Taking the name Daisuke Umon, Duke Fleed works at the ranch run by Danbei Makiba (based on Abashiri Daemon of Go Nagai's manga ''[[Abashiri Ikka]]'').

Roughly two years later, [[Koji Kabuto]], after studying abroad, returns to Japan in a flying saucer he personally designed and built, called the TFO. He heads to the Space Science Lab after hearing of multiple sightings of "flying saucers". He plans to contact the aliens if possible and make peace with them. Daisuke, however, scoffs at the notion and fears that these aliens, the Vegans, led by generals [[Blaki]] and [[Gandal]], are preparing to attack Earth. Koji ignores his warnings and flies out to meet the incoming saucers, only to discover the horrible truth. In order to save Koji and protect his adoptive homeworld from destruction, Daisuke is forced to return to his true identity as Duke Fleed. He unearths Grendizer from its hiding place under the lab and sets off to fight his enemies.

The Vegans establish a base on the [[far side of the Moon]] and start to attack Earth from there. Koji discovers Duke Fleed's true identity and their bitter rivalry soon turns to friendship. The daughter of Danbei Makiba, Hikaru, also discovers Daisuke's secret and becomes a pilot in order to assist him despite his objections. Later on, it is revealed that there were two more survivors from planet Fleed: Duke's younger sister Maria Grace Fleed and a man who had rescued her and fled to Earth, raising her under the guise of her grandfather. Caught in a crossfire between Grendizer and a Vegan beast, he reveals to Maria that she is the last survivor of the royal family of Fleed (under the belief that Duke was killed) before dying from his wounds. Maria swears revenge on Grendizer and its pilot. She tries to ambush Duke, Koji and Hikaru at the Space Science Lab, but the fight is short. Maria's attacks bring Duke's necklace (which is the same as the one she wore) into view and the truth is revealed. The lost siblings are reunited at last and Maria becomes the last addition to the team.

As the conflict nears its end, it is shown that Duke Fleed was engaged to King Vega's daughter, Princess Rubina, prior to the attack on Fleed. When Rubina discovers that planet Fleed is no longer polluted with Vegatron radiation and that her fiancé is alive and well, she rushes to Earth to bring him the good news. Unfortunately, one of King Vega's generals uses this opportunity to ambush Duke Fleed, and Rubina is killed when she takes a shot aimed at Duke. This makes Duke even more determined to wipe out the Vegan menace once and for all.

King Vega decides to gather his remaining forces and make an all-out attack on Earth, destroying the Moon Base to coax his troops into fighting to the end and finally succeed in invading Earth and taking it as their new home planet. Duke and company go out to intercept them in Grendizer and the newly designed space combat Spazers. After a fierce battle, they finally manage to destroy the Vegan mother ship along with King Vega himself. Soon afterwards, Duke and Maria bid a tearful farewell to Earth and their friends and return to help reconstruct planet Fleed.

''UFO Robo Grendizer''<nowiki/>'s origins dates back to ''[[Uchu Enban Daisenso]]'' (宇宙円盤大戦争, ''Uchū Enban Daisensō''), translated and also known as ''Battlefield of The Space Saucers'' and ''The Great Battle of the Flying Saucers'', a 1975 animated short film created by Go Nagai and produced by Toei Doga. It is also known as ''Space Disk War'' and was also released in Italy under the name ''UFO Robot Gattaiger-La grande battaglia dei dischi spaziali''. It was originally shown along with the short film ''Great Mazinger tai Getter Robot G: Kuchu Daigekitotsu'', also from Toei and Nagai.{{citation needed|date=April 2023}}

Nagai and Dynamic Productions created Grendizer using some of the elements and characters from Daiseno including Duke, the Makiba family, and even Blaki. Some changes were made to make it more original. The most obvious are the changes in design and the addition of characters such as Koji Kabuto and Maria Fleed.

''UFO Robot Grendizer'' was developed to be a sequel to ''Great Mazinger'' after the initial concepts of a sequel were rejected by Toei. With the appearance of ''Uchu Enban Daisenso'' at the March 1975 Toei Manga Festival a remake was pitched using elements from ''Mazinger''. To breathe new light into the series, the villains of the series were decided to be aliens, a trend that followed in other Toei mecha series while also making Duke a more Blue Blood character with his suit being based on a knight including more romantic elements with its characters and sense of adventure.{{citation needed|date=April 2023}}

Go Nagai, however, at one point stated in an interview that the anime series was considered a fun side project and does not consider ''Grendizer'' to be part of the series timeline. This is mainly because he had many disagreements with Toei and Shingo Araki over the direction the show should take as well has Toei not paying him royalties for the show's overseas airings, which culminated in a 1986 court settlement that lead to Toei paying Nagai his royalty earnings. In the end, ''UFO Robo Grendizer'' is more of a stand-alone spin-off in the ''Mazinger'' universe.{{citation needed|date=April 2023}}

==Media==

===Anime===
The series was first aired on [[Fuji TV]] from October 5, 1975, to February 27, 1977, with a total count of 74 episodes. Replacing ''[[Great Mazinger]]'' in its initial timeslot. [[Isao Sasaki]] performed both the show's opening and ending themes: {{Nihongo|"Tobe! Grendizer"|とべ!グレンダイザー|Tobe! Gurendaizā|"Fly! Grendizer"}} (with Columbia Yurikago-kai and Ko'orogi '73) and {{Nihongo|"Uchuu no Yuusha Grendizer"|宇宙の勇者グレンダイザー|Uchū no Yūsha Gurendaizā|"Grendizer, Hero of Space"}}. [[Shunsuke Kikuchi]] composed the music for the series.

===Home media===
Toei released the entire series in Japan on DVD from May 21 to October 21, 2006. In 2013, following an agreement with Toei, an official "fully remastered and uncensored" DVD release of the complete series is available on [[List of countries where French is an official language|French-speaking countries]] following the controversy regarding the unlicensed DVD releases by Manga Distribution and [[Déclic Images]] which resulted to a court ruling to pay €7,200,000 back to Toei. The series has also aired on the French [[Mangas (TV channel)|Mangas]] anime TV channel.<ref>{{cite web |url=http://goldorak.mangas.fr/default.aspx?page=tv |title=Archived copy |access-date=2013-11-04 |archive-date=2013-09-28 |archive-url=https://web.archive.org/web/20130928030927/http://goldorak.mangas.fr/default.aspx?page=tv |url-status=dead }}</ref> The entire Arabic dub is available on ''Istikana'', a paid streaming service that has On-Demand Arab movies and TV shows.<ref>{{cite web|url=https://www.istikana.com/en/episodes/grendizer-1|title=Istikana - On-Demand Arabic Independent films, documentaries, shorts, and classics}}</ref>

===Manga===
The manga adaptation was serialized in several magazines in Japan, notably in [[Akita Shoten]]'s ''Boken Oh'' magazine from October 1975 to March 1977. A remake of the series, titled {{Nihongo|'''''Grendizer Giga'''''|グレンダイザー ギガ|Gurendaizā Giga}} was serialized in [[Akita Shoten]]'s [[Champion Red]] magazine from September 2014 to July 2015.<ref>{{cite web | url=https://www.animenewsnetwork.com/news/2014-08-17/go-nagai-to-launch-grendizer-giga-manga-in-september/.77705 | title=Go Nagai to Launch Grendizer Giga Manga in September | date=4 September 2023 }}</ref> Two tankobon volumes were released.<ref>{{cite web | url=https://www.animenewsnetwork.com/news/2015-07-19/go-nagai-ends-grendizer-giga-manga/.90631 | title=Go Nagai Ends Grendizer Giga Manga | date=4 September 2023 }}</ref>

Grendizer makes several cameos in other media, one in 2002 in the sixth chapter of ''Dynamic Superobot Wars'' and in 2004 in ''Dynamic Heroes'', also known as {{Nihongo|''Nagai Go Manga Gaiden—Dynamic Heroes''|永井豪まんが外伝 ダイナミックヒーローズ|Nagai Gô Manga Gaiden Dainamikku Hîrôzu}} and as ''Go Nagai Manga Heroes Crossover Collection—Dynamic Heroes'', a Japanese manga based on several works of Go Nagai, including most of his most famous robots, such as Mazinger Z, Getter Robot and Great Mazinger. It was originally published as a monthly manga magazine e-manga from Kodansha, from June 2004 to July 2007.

===Video games===
Characters from the series also appeared in several installments of [[Banpresto]]'s (now [[Bandai Namco Entertainment]]) popular crossover video game series ''[[Super Robot Wars]]'', making its debut in the second installment of the franchise, ''[[2nd Super Robot Wars]]''.  In recent years, however, Grendizer has made far less appearances in the mainline games but has recently been making a comeback starting with ''[[Super Robot Wars MX]]''.

===Toys===
Japanese Toy company Popy released several toys based on the mechs on the series in the show's initial run in Japan under both the [[Chogokin]] and [[Jumbo Machinder]] labels, which were later released in the United States in the late 1970s by [[Mattel]] as part of the [[Shogun Warriors (toys)|Shogun Warriors]] line of super robot toys.
The titular mecha is also included in [[Bandai]]'s line of ''[[Soul of Chogokin]]'' figures, starting with the GX-04 Grendizer.

==Cultural impact==
{{Overly detailed|details=Too many details that favored Europe and Middle East that it basically made it more like a propaganda than a cultural impact. Rewriting it in a much shorter but precise detail is needed|date=July 2024}}
''Grendizer'' was the second longest running animated ''Mazinger'' series in Japan, having 74 episodes. However, it has been criticized about its connection to the other ''Mazinger'' series in the franchise, especially with Koji's status as a mere sidekick and giving him a different romantic interest who was not Sayaka, as well as the lack of the other ''Mazinger'' mechs.

This created the popular assumption that the anime was not a success in Japan, especially since the merchandise based on the anime did not sell as well as the merchandise for both ''[[Mazinger Z]]'' and ''[[Great Mazinger]]''. However, Go Nagai disputes this, saying the anime was actually quite successful in Japan: “It was actually a hit in Japan. Maybe some people thought it was not as popular as ''Mazinger Z'', because ''Mazinger'' was super popular.”<ref name="arabnews.com">{{cite web|url=https://www.arabnews.com/node/1574326/saudi-arabia|title = How Japanese anime 'Grendizer' galvanized the Arab world|date = 25 October 2019}}</ref> The average viewership metrics for ''UFO Robot Grendizer''<nowiki/>'s original Japanese broadcast was around 20.9% audience share across its 74 episodes with a peak share of 27.6% for Episode 21.<ref>{{cite web|url=http://www.animemorial.net/en/185-UFO-Robot-Grendizer|title = UFO Robot Grendizer (1975's anime TV series) - animemorial.net}}</ref>

Regardless of its disputed success in Japan, ''Grendizer'' was one of the first anime programs to be a major success in both Europe and the Arabic regions of the Middle East, and continues to have a strong following in those parts of the world to this day. It only had limited success in the United States, where it was one of 5 mecha shows included in the 1980 TV anthology ''[[Force Five]]''. The series was renamed ''Grandizer'' for the American market, and only had 26 episodes, which were run out of order. Despite the low episode count, it enjoys a small but dedicated cult following among East Coast American viewers who saw the show as children, as well as children who grew up with military families because ''Force Five'' was frequently aired on the cable TV feed of US military installations in Europe.{{Citation needed|date=May 2023}} This was also the version of the show broadcast in the United Kingdom, India, and the Philippines (though an earlier local Filipino English dub of the show existed before it was taken off the air by orders of the Ferdinand Marcos regime).{{Citation needed|date=April 2025}}

===Europe===
In Europe, Grendizer was a major success in France and Italy, known in both countries as ''Goldorak'' and ''Goldrake'' respectively.<ref>{{Cite book |title=An Illustrated Guide to Samurai History and Culture: From the Age of Musashi to Contemporary Pop Culture |publisher=[[Tuttle Publishing]] |others=Foreword by Alexander Bennett |year=2022 |isbn=978-4-8053-1659-7 |location=North Clarendon, Vermont |pages=240}}</ref> In Italy, the Italian dub theme songs were among the best-selling singles of 1978, with the first selling over 700,000 copies and the second selling over 1,000,000 copies.<ref>{{cite web|url=https://www.hitparadeitalia.it/hp_yends/hpe1978.htm|title=Hit Parade Italia - Top Annuali Single: 1978}}</ref> It would also get its own comic series titled ''Atlas UFO Robot Presenta Goldrake (Atlas UFO Robot Presents Goldrake)'', whose story diverged even further from the source material. This comic ran for 89 issues and spawned several other similar comic adaptations of anime airing on Italian television at that time.<ref>{{cite web|url=https://comicvine.gamespot.com/atlas-ufo-robot-presenta-goldrake/4050-52135/|title = Atlas Ufo Robot Presenta Goldrake (Volume)}}</ref>

The French dub was the first anime series to be telecast in France and legend goes that the series was so popular among French viewers that several episodes scored a 100% TV rating. Like the Italian dub, it changed all of the characters’ names and inserted additional songs, although it did translate the series’ original opening and ending themes into French. Some versions of the dub have a completely different theme simply titled "Goldorak", which was sung by Franco-Israeli singer [[Noam Kaniel]]. Kaniel's performance earned him unprecedented celebrity status in France; by the time ''Goldorak '' had ended its original run on French TV, its theme song achieved platinum status in France.<ref>{{cite certification|region=France|source=infodisc|type=single|artist=Noam|access-date=20 June 2022}}</ref>  The Francophone dub was also one of the first anime programs to be a major success in Canada where it was broadcast on Quebec's [[TVA (Canadian TV network)|TVA network]]. The show continues to have a strong following, garnering widespread news coverage of its DVD release and return to broadcast TV in Canada. In October 2021 a fully licensed French-language ''Goldorak'' graphic novel was released by Editions Kana. According to the creative team, Go Nagai himself gave his blessings to the comics story, which serves as a sequel to the original Toei anime set 10 years after the final episode. The comic has received positive reviews from readers for its detailed art and a story that keeps the spirit of the original series.<ref>{{cite web|url=https://www.actuabd.com/Goldorak-le-retour-en-album-en-2021-chez-Kana|title=Goldorak, le retour en album en 2021 chez Kana}}</ref> To coincide with the graphic novel's release, the French postal company, [[La Poste (France)|La Poste]] issued stamps inspired by the anime.<ref>{{Cite news|url=https://www.manga-news.com/index.php/actus/2021/10/13/Goldorak:-une-bande-annonce-pour-la-BD-de-Kana-et-des-timbres-pour-le-dessin-anime|title = Goldorak: Une bande-annonce pour la BD de Kana, et des timbres pour le dessin animé, 13 October 2021| newspaper=Manga-News.com }}</ref>

''UFO Robot Grendizer Raid'' was released theatrically as ''Goldorak'' and became a hit at the French box office, selling 922,964 tickets upon release in 1979.<ref>{{cite web |title=Goldorak (UFO Robot Grendizer Raid) |url=http://www.jpbox-office.com/fichfilm.php?id=7653 |website=JP's Box-Office |access-date=12 April 2022}}</ref>

===Arab World===
In Arab countries, the show was extremely popular, first airing in [[Lebanese Civil War|war-torn]] Lebanon on [[Télé Liban]] in 1979 under the title '''مغامرات الفضاء: يوفو - غرندايزر''' (''Moughamarat Al Fada: UFO - Grendizer, Adventures In Space: UFO - Grendizer'') before being distributed to most other Arabic speaking regions. Unlike the Italian and French dubs, the Arabic dub retained the characters’ names and kept songs from the Japanese version. Unlike most other Arabic dubs of anime, the show retained most of its plot details without any alteration or censorship in most Arabic-speaking markets, although some markets—such as Saudi Arabia and the UAE did censor certain scenes.<ref>{{cite web|url=https://www.dailymotion.com/video/x7w75mf|title = مغامرات الفضاء جرندايزر الحلقة 46 - فيديو Dailymotion|date = 14 September 2020}}</ref>

The Arabic language version of ''Grendizer'' was so popular when it first aired that it spawned several long-running ''Grendizer'' comics published for the Arabic market. Many of these were translations of the Italian-produced comics, the most well known of these being for the Lebanese comics anthology '''ما وراء الكون''' (''Ma'Wara El Koun, Beyond The Universe''). The magazine founded by Lebanese publisher Bassat Al Reeh (Flying Carpet) and headed by the company's editor Henry Matthews, published Arabic translations of [[science fiction]] comics ranging from one-off short stories to licensed ''[[Star Trek]]'', ''[[Star Wars]]'', and [[Marvel Entertainment|Marvel]] superhero comics, as well as TV licensed comics adaptations like ''[[Six Million Dollar Man]]'' and ''[[The Bionic Woman]]''. ''Grendizer'' did not make its appearance until the fifth issue, but was so popular that it became the top feature on the title, running for 140 issues.<ref>{{cite web|url=https://www.youtube.com/watch?v=4bXHmkWdg1I|title = Memories With Beyond The Universe Comics - ذكريات مع كوميكس ما وراء الكون|website = [[YouTube]]| date=21 August 2016 }}</ref><ref>{{cite web|url=https://arabcomics.net/phpbb3/viewtopic.php?p=2379#2379|title = عرب كوميكس -تسجيل الدخول}}</ref><ref>{{cite web|url=https://www.marefa.org/%D9%85%D8%A7_%D9%88%D8%B1%D8%A7%D8%A1_%D8%A7%D9%84%D9%83%D9%88%D9%86 |title=ما وراء الكون - المعرفة |work=المعرفة |language=ar |publisher=Marefa.org |access-date=2022-08-31}}</ref> It later spawned its own comic series titled '''مغامرات غرندايزر''' (''Moghamarat Grendizer, Grendizer Adventures'') that ran for over 70 issues.

Although the conversion works of the original Japanese version into Arabic had kept the Japanese phonetics, sites and cultural references, the cartoon has actually blossomed into a life of its own. As such, the domestication process of this character and of its whole narrative set was intimately connected to the Arab context and politics at the inception moment of the series,  thus mirroring the deep preoccupations of the generations of that time. High exposure to violence, aggression, and injustice in the Middle East had established a hospitable environment for the super-powerful resistance figure and pro-justice hero."<ref>{{Cite journal|url=https://www.mutualimages-journal.org/index.php/mi/article/view/9-2|doi=10.32926/2020.9.elm.grend|title=Influence and success of the Arabic edition of UFO Robo Grendizer: Adoption of a Japanese icon in the Arabic-speaking world|year=2020|last1=El Mufti|first1=Karim|journal=Mutual Images Journal|issue=9|pages=3–37|s2cid=243283409|doi-access=free}}</ref> Go Nagai stated in an interview with ''Arab News'' that he believes the geopolitical climate in the Arab world played a big role in ''Grendizer'' becoming popular in Arab regions.<ref>{{cite AV media |date=October 25, 2019 |url=https://www.youtube.com/watch?v=K0_ScnfJfYk |title=Mangaka Go Nagai on the geopolitics of Grendizer's success in the Arab world |publisher=[[Arab News]] |via=[[YouTube]] |access-date=October 5, 2021 |archive-url=https://web.archive.org/web/20210302005106/https://www.youtube.com/watch?v=K0_ScnfJfYk |archive-date=March 2, 2021 |url-status=live}}</ref>
