Hello, I am here to share something I find quiet interesting. I heard somewhere that the aura trio from XY was inspired from many culture like greek mythology and also inspired by hindu mythology which is worship in India. I did my own research about it and found out that there are some similarities between the aura trio and the trinity god of hindu mythology. Like, zygarde's 50% form is a snake with five head like pattern behind it. In hindu trinity, vishnu sits on a snake that has five heads. He is also the one who maintains balance and order on earth like zygarde. Xerneas is brhama because both of them gives life and yuveltal is shiva because both of them represents destruction. I think game mixed many culture and mythology to create the trio. But the designs of Xerneas and yuveltal is most probably based on greek mythos. With this, maybe we can find out who this 'A' legendary is. Maybe it will be a mix of the squirrel from greek and a god from hindu.
