The device is designed to give a living thing the ability to morph. Though because it was designed to fit Andalite Physiology, there are unfortunate side-effects for the morph capable humans. So far the only known side effects are the inability to immediately and completely heal any physical damage done to the morphs as scars will remain on the body even if you revert back to your regular body. The morphs are able to heal slowly over a few days as long as they are allowed to rest enough.

The Cube is also a miniaturized gateway to Z-space. It is used to store any extra mass for when the morphers have to morph smaller creatures than themselves. While in Z-space, the extra mass will be protected from Z-space travelers thanks to an energy field the cube creates around the mass. Z-space is also used to create extra matter for when morphers require to use bigger Morphs.

Each manufactured device is given to a Prince with a Preset DNA form from any 10 DNA strands Andalites have for testing. They also give a secondary default morph that is based on the Morpher's personality and knowledge of creatures. Using this information a DNA strand is reverse engineered to give them that creature. A War-Prince is a also given the same device, but because of their status, the Escalif Device is given an extra Perk. The War Escalif gives 7 default DNA compared to the 2 default ones the regular device gives. 3 for stealth missions, 3 deadly species for combat and the 1 for infiltration. The War Escalif does not have a Spirit Walker.

Advanced beings like the mysterious Crayak and Elemist knew just how to manipulate it to access alternate functions that not even Andalites know about. Like the morph lock, a temporary time in which you can stay in morph for more than the time limit without the danger of becoming a nothlit. There is also the DNA melding; however, it is only exclusive to Andalites, but it doesn't stop the godly entities. But Crayak is the only one to be able to gift the ability to incorporate foreign abilities into their base form and to evolve or devolve DNA.
