Metron
Metron is a New God and is the supreme explorer, scientist, and inventor of their world. His mission can be simply put as discovering of the mysteries of the universe. While he is not tied directly to either New Genesis or Apokolips, his origins are enigmatically hidden. With DC currently sporting the Multiverse in their TV shows, its likely their movies will do the same. What better way to set the stage than to include a God who can explain it all to them with ease.
