Polymorphic Crystal is an object related to the Polymorphs.[DJW 1] It was originally owned by Inspector 13 after which Albedo stole it in order to complete his new Ultimatrix and unlock his aliens' Ultimate forms.
A Polymorphic Crystal is a very small reddish-pink polyhedron-shaped jewel.
It appears in The Ultimate Heist, when Inspector 13 shows it to Albedo. Later Albedo claims it and fuses it with his Ultimatrix so that he could access the Ultimates.
This crystal has immense power despite its size, since when fused with any object it becomes much more powerful. Inspector 13 had it to power up the weapon he wanted, as he did with one of his pistols to attack Albedo as Humungousaur. When Albedo fused it with his Ultimatrix, it allowed him to access the Ultimates.

- A Polymorphic Crystal cannot transform the Omnitrix into an Ultimatrix.[DJW 2]
- The way the crystal is shaped is similar to an icosahedron.
