Klaus

Klaus is a character in Xenoblade Chronicles and Xenoblade Chronicles 2. While not a frequently-appearing character, his actions are central to the nature of the world of the stories.

Appearance and personality
Klaus has shoulder length blond hair and blue eyes. He wears a white lab coat with his ID badge clipped on the right side of the coat, a striped collar shirt with a blue tie, denim jeans and black shoes.

Not much of Klaus's personality is known. Although in Xenoblade Chronicles he is portrayed as an arrogant man who cared nothing of the consequences when he conducted his experiment to create a new universe. However in Xenoblade Chronicles 2 suggests that he lost hope for humanity, that he wanted a way out from the war between the Beanstalk and the Saviorite Rebels, and that the Conduit was gifted to him by a divine entity.

Xenoblade Chronicles
Klaus only appears in the finale of the game, as Alvis is explaining to Shulk the true nature of the world. He is a scientist whose selfish curiosity triggered the destruction of the universe and creation of a new one, in which he became one of its two gods. From there, he created the Bionis and all life upon it, and eventually became known as Zanza.

Xenoblade Chronicles 2
At the start of the game's final chapter, a flashback to the year "20XX" is shown. Klaus was a scientist on board the First Low Orbit Station on Earth when the Saviorite Rebels started attacking. The director gives the order to activate Aion via the Conduit as a last resort, but Klaus locked him out in order to carry out a universe creating experiment. His colleague Galea was against it and tries to persuade him not to go with it. Klaus, having lost faith in humanity, believing that the Conduit was a gift from a divine entity, with Galea retorting that is a meta-universe manifold, but Klaus activated the Conduit regardless despite Galea's protests. Light envelops the Earth, and the results are unclear.

As the party eventually meets the Architect, he reveals that he is Klaus. Activating the Conduit caused much of the life on Earth to be sent to other universes, including half of himself, so he believes it is his duty to use his newfound powers to recreate life.
