Emmanuel is a Hebrew masculine given name or surname which means "God is with us." Emmanuelle is the feminine version of the name. In Judaism, with regard to the written Torah and Tanakh, the name "Immanuel" is known to be without any Messianic significance. In contrast, Christian theology interprets the name in the light of the Gospel of Matthew 1:23 relating it to the divine Jesus, the Christian savior, and alleges that it was a prophetic name used in Isaiah 7:14 in the Christian Old Testament.
The avatar Emmanuelle's name is symbolic for her purpose in the story - to save Joseph Adama from wasting his life in New Cap City, and from deserting his family in the pursuit of chasing the ghost of his dead daughter.
