The basic form is a cell-like organism.. all bigger organisms are made of many cells. What more do people need? It's not that confusing of a concept, or is it?
I mean, this is the most legit reason for a pokemon with very drastically different forms that I can think of. Cells combining into curious designs with different ones at different stages, it's like the obvious thing to do. The mythological references are the part that no one expects people to notice without and digging and they are simply what make the specific choices of "creatures" less random, but the concept itself? I just assumed everyone would get thst, considering that they even flat out call the blobs Cell and Core Zygarde...
