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.

This article is written from a Real World point of view.

Elfangor's Secret is the third book in the Megamorphs series. With respect to continuity, it takes place between Books #29: The Sickness and #30: The Reunion.

Megamorphs #4[]

Main article: Back to Before
Back to Before is the fourth and final book in the Megamorphs series. With respect to continuity, it takes place between Books #40: The Other and #41: The Familiar. In this book, Jake is tempted by Drode into accepting an alternate reality in which the Animorphs never receive the morphing power. The results are drastic: Tobias becomes a Controller after joining The Sharing and is later killed for being infested with a Yeerk that was a spy for Visser One; Marco and Rachel begin to date, and both are later killed; Ax escapes the Dome ship even without the Animorphs' help and begins to warn the people of Earth about the Yeerk invasion; Cassie is killed by a Dracon beam, but comes back to life as she is sub-temporally grounded (an anomaly), and she grounds the true timeline. The Ellimist reveals that they would have won in this timeline, but they would have all died.
