Viridi started off as a lab experiment. A liquid green ooze who came to life and escaped into space after finding the true intentions of the scientist who brought him into being. Escaping in a pod, the living ooze landing on Earth where he encountered a girl who wanted a friend. Together they fought crime with his powers to scale in size and stretch his body into any shape.
Shortly after developing this storyline, Viridi was official born on September 11, 2017. A member of a volcanic lifestyle species called the Hephaedians. A name who honors Hephaestus, god of fire and blacksmithery, and Hades, god of the underworld. The Hephaedians as well as other inhabitants treat the flowing magma and lava as the life giving property of the planet - similar to how we treat water.
