#I really like big tree god to the point that rather than being a placeholder for A I would want to give it a role in an AU instead

my sort-of AU idea proposal is that the ultimate weapon draws its power from Arbordrasil indirectly; it was partially made from the root materials (its own plus other roots that grow separately from it) teemed with regenerative and draining power. Its roots themselves are capable of physical regrowth. It also can stretch its branches/vines outwards!

While lying dormant within a gorge of sorts, Arbordrasil's roots eventually rose to surface in a labyrinth-like spiral, which AZ came to randomly discover some day prior to the creation of the machine. He then extracted the materials and used them to create the pre ultimate weapon machine to bring Floette back. In the process, it required input which basically meant the drainage of other lives was required (think of it like roots draining nutrients from the soil to supply and sustain its growth).

Then the conversion to the ultimate weapon came to be, which swelled with overflowing power (the root material absorbed so much from the lives of pokemon that there was still enough energy residue that would then serve the recipe for disaster.)
