Type: Null helmet is Arceus's Cross, but in a smaller/more helmety shape. The point of alchemy is to achieve the power of Azoth aka God aka Arceus. But the hexagons and being made from Zygrade Cell's is definitely possible.
There is so much to this Pokemon it's insane.
I can't wait for Gen 4 to be remade in the AZOTH continuity. Pokemon's new meta story is so amazing.
