Klaus Grad

History
Klaus is a top member of the third branch of an anti-government organization known as Katharon, which opposes the Earth Sphere Federation and its elite squad A-Laws. After an almost failed rescue mission on the Proud succeded with the help of Celestial Being and its Gundam units, Klaus seems grateful and claims that this might be a chance to get the help of someone who shares their goals and helps them back in return when they need help.

When Celestial Being recruits Katharon member Lyle Dylandy to take his late brother's place as Gundam Meister Lockon Stratos, Dylandy begins a regular correspondence with Klaus to report their activities. He informs Klaus about Operation Allelujah Rescue, which also saw the retrieval of Marina Ismail. Klaus informs Shirin Bakhtiar, another Katharon member who formerly served as a personal advisor to Marina.

When Katharon learn (through Lyle) that the Celestial Being mothership Ptolemaios 2 is headed for Azadistan to return Marina, Klaus decides to follow them because they need Celestial Being for their own goals and so that they can protect Marina.[2] They help Celestial Being stave off an attack by A-Laws and meet up with Marina and Setsuna F. Seiei.

Later, he confers with Setsuna, Marina and other members of Celestial Being, and offers Katharon's allegiance. When A-Laws begin their assault he orders them to strengthen their defenses and wait for Celestial Being to save them, but is also caught up in the mayhem caused by the invasion of Automatons to their main base. After its destruction, Klaus leads the survived members to another branch of Katharon.
