"It was sky blue and square, maybe four inches on each side. It seemed kind of heavy for being so small."

An Escafil device, often referred to as the blue box or the morphing cube, is the name of the blue box that grants individuals the morphing ability. It is named after the Andalite scientist Escafil, who helped create it. The Escafil Device was responsible for bestowing the Animorphs with their signature powers, as well as allowing Yeerks and Taxxons to escape their biological limitations, which played a pivotal role in ending the war.


Andalite Usage

"The morphing technology is so new that there are even Andalites who doubt its safety or usefulness. Fortunately, I had a friend back on the home world whose mother was one of the designers of the Escafil Device. She had shown it to me. I'd used it."

The Escafil device was created by a group of Andalites, spearheaded by one named Escafil,[2] in the 1960s.[3] The device allowed for anyone who touched the box, when activated, to receive the power to morph into any individual whose DNA pattern they acquired.[1] One of the designers working on the Escafil Device brought one of the cubes home, where her daughter showed it to her friend, Aldrea-Iskillion-Falan; Aldrea then interacted with the cube and gave herself the ability to morph.[3]

After the technology was perfected, all members of the Andalite military were required to touch the Escafil device and obtain morphing powers in order to pass a mandatory morphing proficiency test.[4] Despite the fact that all active duty Andalites were morph-capable, most Andalites did not morph after the proficiency test. Morphing was usually done exclusively by Andalites who worked in espionage,[5] although there were some Andalites who secretly morphed into kafit birds for recreation purposes.[4]

The morphing technology was also shared with select civilian Andalites, some of whom became morph dancers known as estreens. An estreen possessed the ability to control each aspect of the morphing process and thus was able to make it look elegant as a performative career.

Elfangor's Cube

Elfangor-Sirinial-Shamtul, a famed Andalite Prince, was given his own Escafil Device. In 1997,[6] Elfangor had the cube placed within his personal fighter. When he landed on an abandoned construction site[1] in a town in California[7] on Earth, Elfangor met five human thirteen year olds[8] named Jake, Rachel, Tobias, Cassie and Marco (who would go on to call themselves the Animorphs) and informed them of the truth behind the Yeerk Empire and their invasion of Earth.

Escafil Device GN1

The Animorphs touch the Escafil Device and acquire the power to morph

In order to help them fight, Elfangor asked Jake to enter his ship and retrieve the blue box. When Jake brought him the cube, Elfangor notified the children that the box would give them the ability to morph into animals and offered to transfer these powers to them. The five human teenagers then placed their hands against each side of the cube as Elfangor actived the cube, granting the five teens the morphing power. The Animorphs then ran as Visser Three arrived on the scene in his Blade ship, along with a pair of Bug fighters. When Elfangor commanded his ship to destroy one of the Bug fighters, the remaining Bug fighter and the Blade ship fired at Elfangor's fighter and destroyed it.[1] The force of the ship's explosion propelled the Escafil Device into one of the walls of the construction site.[2]

Aximili's Cubes

"Captain Asculan issues the following orders: Four morphing cubes will be made available to aristh Aximili to use as he sees fit. Aristh Aximili is hereby elevated to the rank of prince. Prince Aximili is appointed liaison between the Andalite fleet and the people of Earth."
―Andalite Junior Officer to the Animorphs[src]

Human Usage

"Terrorists had begun to attack Andalite tourists and free Hork-Bajir. And the Andalites had agreed to make a single morphing cube available, on condition that it remain in Andalite custody and be used only for antiterror forces."

"That blue box represented more power than half the weapons in the world combined. That little blue box could give anyone morphing power."

In chronological order:


  • David identifies the Escafil Device in The Discovery as being inscribed with symbols, presumably Andalite writing. However, in most official depictions of the Escafil Device it is shown as a featureless cube with no symbols or inscriptions.
  • Some inconsistency exists in the series as to how the box works; while the general canon is that the box must be activated first, in The Hidden, an ant and a buffalo are able to acquire the morphing ability simply by touching the cube.

  6. The Andalite Chronicles is said to take place 10 years after the 1966 Yeerk exodus of The Hork-Bajir Chronicles and 21 years before Elfangor met the Animorphs. This places it in 1976, meaning the Animorphs met Elfangor in 1997.
