is a Japanese science fiction mecha anime media franchise, created by Studio Nue (most prominently mecha designer, writer and producer Shōji Kawamori) and Artland in 1982. The franchise features a fictional history of Earth and the human race after the year 1999, as well as the history of humanoid civilization in the Milky Way. It consists of four TV series, nine movies, six OVAs, and multiple light novel and manga series, all produced and sponsored by Big West, in addition to 40 video games set in the Macross universe, two crossover games, and a wide variety of physical merchandise.

Within the series, the term Macross is used to denote the main capital ship. This theme began in the original Macross, Super Dimension Fortress Macross.

"Overtech" refers to the scientific advances discovered in an alien starship ASS-1 (Alien Star Ship-One later renamed Super Dimension Fortress-One Macross) that crashed on South Ataria island. Humans were able to reverse engineer the technology to create the mecha (variable fighters and destroids), faster-than-light space fold drive for starships and other advanced technologies that the series features.

Title

The series title comes from the name of the main human spacecraft (which is usually shortened from Super Dimension Fortress Macross to "SDF-1" or The Macross as it is the first). The original name for the Macross project was Battle City Megarōdo (or Battle City Megaroad, as the Japanese transliteration to either "L" or "R" gives the title a double meaning in reference to the story line: Megaload, referring to the spacecraft containing an entire city of people; and Megaroad, referring to the long journey through space back to Earth); however, one of the sponsors of the project, Big West Advertising, was a fan of Shakespeare and wanted the series and the spacecraft to be named . A compromise was made with the title due to its similar pronunciation to Macbeth in Japanese and because it still contained connotations to the original title. The word Macross comes from a wordplay combination of the prefix "macro" in reference to its massive size in comparison to human vehicles (though when compared with the alien ships in the series, it is a relatively small gun destroyer) and the distance they must cross.

Themes The following are themes commonly seen and established among the various series in the Macross franchise.

U.N. Spacy

The is a fictional space military arm of the . It was established by the successor to the modern United Nations in order to defend Earth from a possible attack by hostile aliens, and was involved in Space War I against an extraterrestrial race called the Zentradi. Later operations of the U.N. Spacy expanded into interstellar colonization and general peacekeeping of off-world Earth settlements.

The term "Spacy" is a portmanteau of the terms Space and Army or Navy. Some Japanese sources also use the term Space Army and some English-language sources use the term Space Navy, suggesting that the term is a contraction.

Variable fighters The valkyrie fighter is one of a series of transformable aerospace fighters, primarily designed by franchise creator Shōji Kawamori and Kazutaka Miyatake. They are generally able to transform into jet/space fighters, Battroid (a humanoid robot) and a hybrid of the two modes, called Gerwalk (Ground Effective Reinforcement of Winged Armament with Locomotive Knee-joint). The VF-1 was specifically named "Valkyrie", but all of the jet fighter craft have generically been referred to as such in the series since then.

Music Music is integral part to almost every Macross title by having significances in a series' antagonists behavior towards it. Music idols also play a central role to various Macross stories. Often, the protagonist will be involved in a love triangle with a series' music idol; most notably, Lynn Minmay.

Space fold Space folding permits nearly-instantaneous ultra-long distance travel: a space-fold transports a spacecraft in a very short amount of time by first swapping the location of the spacecraft with super dimension space or subspace, and then swapping the Super Dimension space with the space at the destination.

According to U.N. Spacy First Lieutenant Hayase Misa during Space War I (2009–2012) an hour passes in super dimension space as approximately ten days passes in normal space. One of the latest Macross TV series, Macross Frontier, further expands on that concept by introducing fold faults or dislocations, which further retard fold travel and interfere with fold communications. Also explained in Macross Frontier are the limitations of space folding, such as the geometric increase in energy requirement with the mass of the object to be folded, which prevents very large objects from being folded with ease across vast distances.

The act of entering Super Dimension space is called "fold in". When arriving at the destination, the act of leaving Super Dimension space is called a "defold" or a "fold out".

Ancient astronauts The metaplot of the franchise is centered on a purportedly extinct humanoid alien race called the . It was first conceptualized during the pre-production of The Super Dimension Fortress Macross when the creators were researching cultural studies to develop concepts used in the plot.

According to official sources, the Protoculture was the first advanced humanoid race in the universe—advanced Protoculture civilization started 500,000 years ago—and is the creator of the Zentradi and Homo sapiens. Phases of colonization resulted in the establishment of an "Interstellar Republic" (similar to a galactic empire), which covers much of the Milky Way galaxy 2800 years after Protoculture civilization started (498,000 years ago).

A civil war happened sixty years later, resulting in a split in the Republic. One of the factions created "super-Zentradi" forces, which was later possessed by interdimensional beings—these forces are later called the "Protodeviln", which feeds on life energy of both Protoculture and Zentradi; some of both the Protoculture and Zentradi was later brainwashed into the "Supervision Army".

The Supervision Army continued to battle both the Protoculture and Zentradi, which resulted in the dwindling of Protoculture population; they revoked the prime directive that banned Zentradi from attacking the Supervision Army. This, however, made the war even more intense, and the Protoculture population sharply decreased; to avoid extinction, they seeded uninhabited planets by means of pantropy and avoided any conflict as much as possible. This action included the genetic engineering of Homo sapiens on Earth by combining Protoculture genes with native genes; a "sub-Protoculture" race meant for preparing the Earth for a future Protoculture colonization. The genetic engineering crew, however, was immediately destroyed by anti–Interstellar Republic military ships.

The final blow of the war happened because of the Protoculture lost control of the Zentradi; 475,000 years ago, the Protoculture was believed extinct. However it was discovered that 10,000 years ago, the Protoculture remnants made contact with humans on Mayan Island, genetically re-engineering the native inhabitants to utilize the artifacts left behind by them. This included the "Bird Human" bio-mecha, tasked to destroy humanity if they are still in war.

Other elements The franchise also explores minor themes including culture shock, capitalism, coming of age and nostalgia.

The new era following the end of Space War I is part of the ongoing fictional time-line of the Macross franchise. The most recent series, Macross Delta, is set 59 years after the start of the war with the Zentradi. Its main plot is about the spread of a rage virus on a star system and the combined efforts of singing idols and valkyrie fighters to stop it spreading.

Along with Gundam, a real robot mecha series of which Shoji Kawamori is a fan, Macross explored how individuals cope with warfare. Whereas Gundam is far more political and direct on the horrors of war, each Macross television series is known for never depicting the antagonists as inherently evil and proved in the end that love, culture, and music can be used to resolve their conflicts.

Series chronology

Several sequel series and one prequel have followed. Most use a chronology created by the Studio Nue creators, and those that followed their own chronologies were regarded as "parallel storylines" by the studio. Several different studios were involved with Studio Nue in the Macross franchise along the years, but since 2002's Macross Zero, production has been handled exclusively between Nue and Satelight, from which Shōji Kawamori is one of the main key members. The main of Macross production consists of (in chronological release order):
