Chronological list This is a chronological list of the Animorphs books by K. A. Applegate, as applies to storyline continuity.
The Andalite Chronicles () This book is divided into three parts: #1: Elfangor's Journey, #2: Alloran's Choice, and #3: An Alien Dies. 1: The Invasion (Spring 1997) 2: The Visitor 3: The Encounter 4: The Message 5: The Predator 6: The Capture 7: The Stranger Megamorphs 1: The Andalite's Gift (Summer 1997) 8: The Alien 9: The Secret 10: The Android 11: The Forgotten 12: The Reaction 13: The Change 14: The Unknown 15: The Escape 16: The Warning 17: The Underground 18: The Decision—() Megamorphs 2: In the Time of Dinosaurs—(Sario Rip time travel to 65,000,000 years ago.) 19: The Departure The Hork-Bajir Chronicles (1966, 1968–69, 1998) Although the events in this story occur between The Ellimist Chronicles and The Andalite Chronicles, the entire story is being told by Jara Hamee to Tobias after book #13, The Change, and before the events of #23 The Pretender. Tobias makes reference to his restlessness and the fact that there were no missions planned (Prologue, pg ix). However, in The Pretender, (pg 12) Tobias makes reference to the fact that they had "worked plenty lately, dealing with the horrifying matter of David, the first new Animorph." This places the last possible "break" before book #20, the first book in the David trilogy 20: The Discovery 21: The Threat 22: The Solution 23: The Pretender 24: The Suspicion 25: The Extreme 26: The Attack 27: The Exposed 28: The Experiment 29: The Sickness Megamorphs 3: Elfangor's Secret (Time Matrix time travel to 10/25/1415, 12/25/1776, 10/21/1805, 1934, 6/6/1944, and 1967) 30: The Reunion—(sometime a little bit before or after 12/18/98) 31: The Conspiracy 32: The Separation—() 33: The Illusion 34: The Prophecy 35: The Proposal Visser (1976, 1980s, 1991–1999) The trial chronicled in Visser is set during and after the events of The Proposal, but the book also covers events before The Andalite Chronicles. 36: The Mutation 37: The Weakness 38: The Arrival 39: The Hidden 40: The Other Megamorphs 4: Back to Before (1999, experimental timeline to 1997) 41: The Familiar 42: The Journey 43: The Test 44: The Unexpected () 45: The Revelation 46: The Deception 47: The Resistance 48: The Return 49: The Diversion 50: The Ultimate 51: The Absolute 52: The Sacrifice 53: The Answer The Ellimist Chronicles (story stretching billions of years into the past) Technically this is set during the same time as the first chapters of The Beginning even though it covers events set far before The Andalite Chronicles. 54: The Beginning (2000-)
Graphic novels A series of graphic novel adaptations, adapted by and with art by Chris Grine, began to be released in October 2020. Each volume adapts one book from the original series.
