"My notions of proper behavior had brought disaster. I was a fool. A silly child living out storybook notions of decency and fairness. There was no decency in war. Alloran had tried to teach me that. I'd learned it too late."

Prince Elfangor-Sirinial-Shamtul (also known as Alan "Al" Fangor) was an Andalite prince who was responsible for giving the Animorphs the power to morph, as well as for advancing human computer software on Earth during his time as a human nothlit. He was the husband of Loren, the father of Tobias and the older brother of Aximili-Esgarrouth-Isthill.


Elfangor-Sirinial-Shamtul is the son of Noorlin-Sirinial-Cooraf and Forlay-Esgarrouth-Maheen, the older brother of Aximili-Esgarrouth-Isthill,[1] husband of Loren and the father of Tobias.[2]


Aristh and Loren

As an aristh, Elfangor was sent on a mission to rescue two humans from the Skrit Na. Although the plan was initially to simply to return them back to Earth and their memories erased, the discovery of the Time Matrix resulted in their return being delayed. This allowed Elfangor and Loren time to develop a deeper, closer bond. Not long after, Elfangor left the war after having his faith shattered, and he came to Earth with Loren.[3]

During a time when Elfangor was on Earth, he performed a Frolis Maneuver, morphed into a human, purposely became a nothlit and assumed the alias of "Alan Fangor". Soon after returning to Earth, Elfangor and Loren were married and together they conceived a child, Tobias. However, Elfangor was eventually returned to the war by the Ellimist. The Ellimist also apparently erased Loren's memory of her life with him while leaving the newly-conceived Tobias still in existence.[4]

After Elfangor was returned to Andalite form and placed back in Andalite space by the Ellimist, he returned to military service. Elfangor was quickly promoted from the rank of aristh to Prince, for ramming the Blade ship of Visser Three with a small fighter ship and disabling it, thus saving an Andalite Dome ship.

During his great adventures, Elfangor made a powerful arch-nemesis, a Yeerk by the name of Esplin 9466. When they first met, Esplin was Sub-Visser Seven and inhabited the body of a Hork-Bajir. During the ensuing conflict, Esplin managed to trick Elfangor to allow him to infest his senior War-Prince Alloran-Semitur-Corrass, giving the Yeerk the access to both Andalite forces' military knowledge and the ability to morph. As his nemesis immediately advanced to the rank of Visser Thirty-Two and later, the rank of Visser Three, Elfangor blamed himself for the loss of his senior, realizing that war is truly horrible and ugly as Alloran described.[5]

Death and the Animorphs

Elfangor's demise comes in his final battle with his arch-nemesis, Visser Three. Elfangor's Dome ship, GalaxyTree, was commissioned to come to Earth to assess the Yeerk's progress. Unfortunately, the Andalites were caught completely off guard by a

hidden Yeerk Pool ship and Visser Three's Blade ship. Elfangor was dispatched along with other warriors to battle the Yeerk Bug fighters.[6] Unfortunately, all the Andalites were killed, and Elfangor's ship was damaged and crash-landed in an Abandoned Construction Site onto Earth. While Elfangor lay dying, five human teenagers discovered him and he gave them the power to morph to defend Earth against the Yeerks. Immediately thereafter, Visser Three arrived, morphed into an Antarean Bogg and devoured Elfangor.[7]


After his death, Elfangor was awarded the highest honor in the Andalite military by having a Dome ship named after him. The Elfangor is the Dome ship that finally comes to Earth to aid the Animorphs in stopping the Yeerk invasion of Earth.[8]

Books Narrated By Elfangor



  • In The Andalite Chronicles, under the guise of Alan Fangor, Elfangor describes how he created an operating system using "windows". He then shared this creation with his friend, simply named "Bill". This would suggest that Elfangor is responsible for the Windows OS, and that his friend was Bill Gates. He also mentioned he talked with someone named Steve, possibly a reference to Steve Jobs or Steve Wozniak from Apple, Inc.
  • In the TV series, he recognized Tobias while giving him, Jake, Rachel, Cassie, and Marco the ability to morph into various creatures with the Escafil Device, and even entrusted the Andalite disc to him. This is because he knew that Tobias was his human son.
  • Elfangor had a Dome ship named after him. The Elfangor is the Dome ship that finally comes to Earth to aid the Animorphs in stopping the Yeerk invasion of Earth.[9]
