Megamorphs are four companion books in the Animorphs series writted by K.A. Applegate. They are different from most of the other books in the series because they are narrated by all of the Animorphs, usually switching point-of-view at the beginning of each chapter. Their exact chronology to the other books is known via the Anibase, which states that it corresponds to the book release dates, however they are numbered as Megamorphs #1, Megamorphs #2, Megamorphs #3, and Megamorphs #4.
