An Escafil device is the technical term for the "blue morphing cube" that gives an individual the power to morph. It goes by other names, but is most well-known as the Escafil device, named after the Andalite scientist Escafil, who helped create the morphing technology. It's a light blue cube that is operated by touch contact, and apparently one person, the "giver," who should already have the morphing ability has to touch one side of it, while those receiving the morphing ability touch other sides. When touched, it gives the user the permanent ability to acquire DNA from live animals and change ("morph") into the animal. Once an individual gains the morphing ability, they do not need to use the Escafil device again.
The morphing technology's exact function is not known, but it is speculated to be a vast network of thousands of microbionic units. These units would be contained in the Escafil device, the central computer for the smaller morphing units.Although the Animorphs had long believed that the Escafil device that Elfangor-Sirinial-Shamtul used to give them their powers was destroyed when his ship was destroyed by the Yeerks, it was later recovered by David- where he picked it up was unspecified, although it was definitely in the construction site-, the Animorphs subsequently reclaiming it. It was briefly used as a power source by the Helmacrons before it was recovered, the Animorphs keeping its location secret due to the dangers of sharing the morphing technology with others.
When fooling David, the group said that it could be, and was, broken into pieces. (These were actually Legos.) It was later disassembled by Ax in The Ultimate, demonstrating that it was able to be broken down.
- In Alternamorphs #1 The First Journey, the Escafil Device is presumably a seven-sided cube, since it is touched simultaneously by the five Animorphs, Elfangor and You. This anomaly is never explained, nor does it recur anywhere else in the series.
- 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 as to how the Escafil Device is operated - in The Invasion and The Discovery, an existing morpher must touch the Device in order to activate it. However, in The Hidden an ant and a buffalo are able to acquire the morphing ability simply by touching the cube. This creates an inconsistency since David handled the cube for days without ever gaining the morphing ability. This inconsistency is never explained, though it may be due to the comparatively recent handling of the device by Animorphs.
