This egg was created in celebration of 500 species at Egg Cave.
Nobody knows how this species is able to do this... but, as it evolves, it is able to morph into other forms and mimic other species' characteristics.
The baby stage of this creature is a Yazan, with two heads sticking out of its side. The teen stage of this creature is a Mo intertwined with a Diablos. Legend has it that these two creatures keep each other in balance and are in a perpetual battle with one another.
Finally, the adult form is a combined creature that mimics the Moxel, Nym, and Adarna.
