Trivia

 * Viperion was first revealed in concept art shown at the 2018 Comic Con Experience panel on December 6, 2018.
 * Viperion's name is likely a portmanteau of viper (a family of venomous snakes) and Hyperion, a Titan of Greek mythology associated with the sun and daytime.
 * In Greek mythology, the priestess of the oracle at Delphi was known as Pythia, stemming from the giant snake slain by Apollo (another god of the sun) "in the strength of Hyperion (day)."
