Xerneas's name "Xerneas" is taken from Latin deer, Sananos, deer and engraving. Sananos is the god of fertility in Celtic mythology, and the carved deer is the god deer in Greek mythology. The reference image of the Phoenix King is just a phoenix. Xerneas is the god of life, and its performance in the 20 14 theatrical version has actually been confirmed. It saved all the creatures that were killed by Yveltal. Xerneas and Yveltal are both called the Poké mon of fate. Their theme and even the theme of the whole sixth generation comes from the famous sentence in Revelation 22 of the New Testament: "I am Alpha, I am Omega; I am the first and I am the last; I am the beginning, I am the end. " The beginning and the end are life and death, so in a word, Xerneas is the god of life.
