The Other is the fortieth book in the Animorphs  series, written by K.A. Applegate. It is narrated by Marco.

Official DescriptionEdit

Ax and the Animorphs have always believed Ax was the only non-infested Andalite on Earth. That he alone survived the terrible battle between his people and the Yeerks.

Until Now.

There were other survivors. Other Andalites. And they're here on Earth. Trying to keep a low profile. Trying to find a way to defeat Visser Three. Trying -- like Ax and the Animorphs -- to stay alive until help finally comes.

If help finally comes...

  • The cover quote is, "This is your brain. This is your brain with a Yeerk. Any questions?"
  • The inside cover quote is, "Busy as a bee...."
  • This was the 3rd book cover (out of 4) to show Marco morphing into an insect, the 1st was in Book 10 The Android (Spider), Book 30 The Reunion (Cockroach), and Book 45 The Revelation (Ant).
  • The topic of disabilities comes up again very significantly in Book #50: The Ultimate. Ax has much less of an issue with it that time around.
  • The Andalites started out the series as the "good guys" against the evil Yeerk "bad guys". But, as K.A. Applegate showed with the Yeerks, no one species is all good or all bad. Here's what K.A Applegate said about the plot of this book: "This was my belated attempt to deal with the issue of disabilities.... I wanted to show a less savory side of Andalite culture, show that maybe they had some problems, too."
  • ANIBASE: After seeing the video of a blurry Andalite, the Animorphs do some digging and discover Gafinilan-Estrif-Valad, a rather large, tough Andalite warrior. He and his fighter pilot shorm, Mertil-Iscar-Elmand, were stranded on Earth after the Yeerks massacred the Andalite's in Earth's orbit. Mertil was somehow wounded -- his tail was cut off, making him a vecol. Now Gafinilan, who is suffering from an Andalite sickness, has taken it upon himself to take care of Mertil and himself until they both die in peace. Only Mertil has been kidnapped by the Yeerks -- and Gafinilan isn't fully resigned to allow himself to die from his disease.
  • While slight undertones were hinted in the books on Gafinilan and Mertil being described as "friends". In an open letter titled Diversity, series Co Author Michael Grant stated they were in fact in a romantic relationship.
