NEXUS is a masculine voice with no specific avatar, but portrayed by the creator as a robotic (in terms of appearance) orb.
It was created to sing, and to deliver music.
Users are free to use their own ways of interpreting the masculine vocal.

(perhaps a usage of Nexus used by someone pro could be a nice farewell song)
