is a sentient Plante, an energy source created by humans, known as "The Humanoid Typhoon" due to the destruction which surrounds him. He is initially discovered by Meryl and Milly, representatives from an insurance agency investigating claims made due to damages caused by the mysterious "Humanoid Typhoon". The pair find Vash while he is being chased by bandits who want to collect the bounty on "The $$60,000,000,000 (sixty billion double dollar) Man". He and his brother, Knives, are born on a colony ship that was part of a fleet sent to find and settle a new world in order to extend the human race. They were raised by Rem, who instills upon Vash the philosophy that every being deserves life, and Vash takes this to the extreme by always attempting to save everyone. Knives on the other hand, sickened by the actions of the human around him, eventually causes the fleet to crash, which kills Rem and many other humans. Vash makes it his purpose to hunt down and stop Knives from harming anyone else. During one of these conflicts with Knives, Vash is forced by Knives to destroy the city of July, which haunts him considerably and starts his reputation.
