Knightmare Profile

The Guren SEITEN, standing for Superlative Extruder Interlocked Technology Exclusive Nexus Despite its incredible performance and the skills of its pilot, Kallen Kouzuki, the Type-02/F1A Guren Flight is defeated in battle in the Chinese Federation by a combination of poor maintenance and the efforts of Li Xingke and his Knightmare Frame XT-404 Shen-Hu. Both machine and pilot are handed over to Britannia by the request of Suzaku Kururugi and taken back to Area 11. While Kallen is imprisoned, the Guren is handed over to Suzaku's subordinates in the Camelot Engineering Corps. The head of the corps, Lloyd Asplund, defers to his assistant Cecile Croomy, allowing her to modify the Guren using a number of technologies intended for Suzaku's new machine, the Z-01Z Lancelot Albion. This includes the Energy Wing System, a new flight option of Cecile's design, which combines incredible propulsion with maser field 'feathers' which can be used in the same fashion as the Blaze Luminous energy shields.

In the end, Cecile by her own admission goes overboard, producing a unit so high-spec that it is thought nobody can truly pilot it, not even Suzaku. However, during the Second Battle of Tokyo, Kallen is broken out of her prison and hijacks the modified Guren, using it to tear through the battlefield and save Zero from the bloodthirsty Knight of Ten, Luciano Bradley.

When the Black Knights rebel against Zero, Kallen struggles with the choice of who to side with, eventually becoming convinced that Zero/Lelouch has truly gone bad and swearing to kill him personally to atone for allowing him to become so powerful. In the final battle over Mount Fuji, Kallen and the Guren face off against Suzaku and the Lancelot Albion in a duel that sees both units dealing crippling damage to one another, finally ending the rivalry between both the machines and their pilots.
