Mamaragan

In Australian Aboriginal mythology, Mamaragan or Namarrkun is a lightning god who speaks with thunder as his voice. He rides a storm-cloud and throws lightning bolts to humans and trees. He lives in a puddle.

In the DC Comics story The Darkseid War the superhero Shazam is empowered by six new deities; one of them is Mamaragan, revealed to be the true identity of the Wizard who originally empowered the hero.
