Viridi (ナチュレ Natyure) is the Goddess of Nature in the form of a young blonde-haired girl with the mentality of an adult. She commands the Forces of Nature as a secondary faction in the game. Originally an antagonist before becoming a protagonist, she can be very witty and sarcastic towards other deities and Pit. Sometimes getting annoyed at their playful jokes because of her very serious approach. She eventually shows her fun side when she aids Pit in his quest.
After Hades tricked humanity into fighting over the non-existant Wish Seed, Viridi deems them unworthy to exist and sends a Reset Bomb to wipe out the warring factions before intending to target the rest of the human race, thus becoming Pit's enemy as she sends Cragalanche on him when he and Palutena interfere. Later as the bulk of her army battle Hades's army, Viridi commands her remaining forces to stop Pit from destroying her Reset Bomb Depot. Despite threatening to kill Pit after he destroys her Reset Bomb Depot, she has a change of heart and becomes an ally after the Aurum invades Earth as she aids the angel in defeating them.
Viridi also aids Pit in freeing Palutena from Chaos Kin's control and allowing him to rest at her sanctuary. She later becomes support for Dark Pit after he defeats Pandora at the Rewind Spring, pulling him back to her realm when he starts falling in the sky before he realized he couldn't fly on his own anymore. She observes the final battle between Hades and Pit, not helping Pit in anyway other than rooting for him and enabling his Power of Flight after the Great Sacred Treasure is shattered. She then reintroduces her issue with the humans, since Hades is no longer a threat, but is forced to drop the subject and let Pit have his happy ending.
