Reposting notes on AZOTH in alchemy
Azoth is the single force -- the "spiritus animatis," as Wikipedia puts it -- of humanity that drives it to attain physical and spiritual perfection. Not only this, the Azoth seems to also have a physical incarnation as the "Elixir of Life" or "The Universal Solvent," and was known as the cure for any mental, spiritual, or physical ailment. Essentially, it's liquid perfection.
Another thing of note is that Azoth's name was constructed from the first and last letters of the Latin, Greek, and Hebrew alphabets, in that order: A/Alpha/Aleph, Z, Omega, and Tau, which ties in to the "Beginning and End" motif present in AZ, and Alpha and Omega.
Additionally, Azoth is another, less used name for the chemical Mercury, which is a part of a very significant trio in alchemy, with the other members being salt and sulfur. The chemical symbols of all three can be seen within the starter Pokemon, as shown in pic related.
