Bardiche is an Intelligent Device forged for Fate Testarossa by her mentor, Linith—Precia Testarossa's familiar—during Fate's early training. This expanded backstory, adapted from *Nanoha Sound Stage 02*, is integrated into *The MOVIE 1st*'s narrative. Linith designed Bardiche to support Fate in combat and magic, establishing their partnership before the film's events. Within *The MOVIE 1st*, Bardiche's physical design features a rounded axe blade, additional curved spikes, and a sleeker profile, differing from the original anime. This change reflects the film's in-universe status as a TSAB-produced semi-biographical work. Fate Testarossa's consultation led to a more sympathetic portrayal of her past, including Bardiche's aesthetic refinements. Bardiche operates primarily in English under Mid-Childan magic protocols, emitting yellow energy. It addresses Fate with the formal "sir." The Device utilizes multiple combat-optimized forms: * **Axe Form**, the default state equivalent to the original Device Form, executes spells like Photon Lancer. * **Scythe Form** transforms the axe head into an energy blade for close-combat techniques such as Arc Saber. * **Glaive Form**, replacing the original Sealing Form, acts as a spear configuration for high-output spells like Photon Lancer Phalanx Shift and sealing Jewel Seeds. Core functions include **Auto Guard**, activated via Fate's *Defenser* spell, and the **Cartridge System** for spell augmentation. These systems are retained from the primary continuity but visually streamlined for the film. Bardiche actively supports Fate in key battles against Nanoha Takamachi over Jewel Seeds. Its forms are strategically deployed across aerial and ground combat, with Glaive Form critical for sealing operations. Bardiche remains Fate's steadfast companion through her emotional turmoil, including conflicted loyalty to Precia and her evolving dynamic with Nanoha. While *The MOVIE 1st* omits later upgrades like Bardiche Assault, the Device's conceptual foundation aligns with the primary continuity's emphasis on adaptability and loyalty. Supplementary merchandise, including figma figures, confirms the film's distinct designs for Axe, Scythe, and Glaive Forms, reinforcing their canonicity within this timeline.
