Animorphs is a science fantasy series of middle grade books written by Katherine Applegate and her husband Michael Grant, writing together under the name K. A. Applegate, and published by Scholastic. It is told in first person, with all six main characters taking turns narrating the books through their own perspectives. The core themes of the series are horror, war, imperialism, dehumanization, sanity, morality, innocence, leadership, freedom, family, and growing up. Published between June 1996 and May 2001, the series consists of 54 books and includes ten companion books, eight of which fit into the series' continuity (the Animorphs Chronicles and Megamorphs books) and two that are gamebooks not fitting into the continuity (the Alternamorphs books). The books were adapted into a television series of the same name on Nickelodeon, YTV and Global Television Network, which ran from 1998 to 1999. The series has also been adapted to audiobook form as well as a series of graphic novels starting in 2020. A film adaptation was officially announced in 2020.
Plot summary The story revolves around five teenage humans: Jake, Marco, Cassie, Rachel, Tobias, and one alien, Aximili-Esgarrouth-Isthill (nicknamed Ax), who obtain the ability to transform into any animal they touch. Naming themselves "Animorphs" (a portmanteau of "animal morphers"), they use their ability to battle a secret infiltration of Earth by a parasitic race of aliens resembling large slugs called Yeerk. Yeerks can take any living creature as a host by entering and merging with their brain through the ear canal. The Animorphs fight as a guerrilla force against the Yeerks, led by Visser Three, who uses an Andalite (a centaur-like race of aliens, which Ax belongs to) as a host. Throughout the series, the Animorphs carefully protect their identities; the Yeerks assume that the Animorphs are a strike force of Andalites, the aliens who created the transformation technology, sent to prevent the Yeerks from conquering Earth. The Animorphs maintain this façade to protect their families from Yeerk reprisals. Though the Animorphs can assume the form of any animal they touch to acquire the DNA, there are several limitations to the ability. The most vital is that they cannot stay in animal form for more than two hours, or they will be unable to return to human form and the morphs become permanent. The Andalite term for this is "Nothlit". Others include having to demorph back to human in between morphs, only tight clothing being able to be carried over with a morph, DNA allergies that can lose some control of the morphing ability, and having to consistently maintain concentration during a morph to prevent the animal's natural instincts from overwhelming their human intellect. A benefit to morphing is that it allows the team to heal any superficial, non-genetic injury, sustained as a human or in a morph. Also, while in morph, they can telepathically communicate with anyone nearby in what they call 'thought-speak'.
Development
Writing The series was originally conceived as a three-part series called The Changelings, in which Jake was named Matt, and his little brother Joseph took the place of Cassie. In an interview with Publishers Weekly, Applegate talked about the source of inspiration and realization for the Animorphs series: "I grew up loving animals and lived with the usual suburban menagerie of dogs, cats and gerbils", she said "I really wanted to find a way to get kids into the heads of various species and decided that a science-fiction premise was the way to do this". Applegate tried to accurately depict the various animals, and did research such as visiting "a raptor center where they rehabilitate injured birds". "When Tobias becomes a hawk, I want the reader to see the world as a hawk might see it—to soar on the warm breezes and hurtle toward the ground to make a kill", she said. To develop the characters for Animorphs, Applegate would go through teenage magazines such as YM and Seventeen (both of which are referenced in the books when describing Rachel), cutting out pictures and piecing them together to get an idea of what sort of children the Animorphs would look like. Applegate stated in an interview online that many of the names for her alien creatures, races, and locations are actually scrambled names of local street signs or companies that she happens to notice. For instance, the word nothlit was derived from the hotel name Hilton. In another interview, Applegate stated that she originally wanted the alien Andalite to have more standard and familiar forms, but was told by Scholastic to be more creative with the designs, which led to her giving them such a distinctive look. According to the Anibase (an officially-produced, Flash-based piece of software once available on the official Animorphs website with detailed information about each book), Applegate did not make up the titles for the Animorphs books: it was up to the Scholastic editors to create the titles for the books based on the outlines provided by the author, having to select a word that not only fit the book's storyline, but sounded good with the characteristic "The" preface. One of the author's favorite books, The Lord of the Rings, lent several words and images to Animorphs: the Sindarin plural word for Orc, "yrch", became Yeerk; the flaming red Eye of Sauron inspired the Crayak, and Ax's middle name, "Esgarrouth", is based on a town in the books called Esgaroth. The human name of Ax's brother, Elfangor, is Alan Fangor and his last name is in reference to the Fangor region or Fangorn Forest. Also there was a minor reference to Gondor, in the form of a fictional company named "Gondor Industries" in the 14th book. Applegate's writing was inspired by her family. All books after The Unknown were dedicated to Applegate's first daughter, Clara, under her former name, as well as Applegate's husband and co-writer, Michael. Her daughter was born premature in 1997, and Applegate worked on the Animorphs series at night, in the lobby of the hospital where she was in Neonatal Intensive Care (NIC).
