Movie
Description
Fate T. Harlaown, originally Fate Testarossa, is an artificial human cloned from Alicia Testarossa by Precia Testarossa. Following Alicia's death in a lab accident, Precia rejected the imperfect Fate, subjecting her to physical and emotional abuse while forcing her to collect hazardous artifacts called Jewel Seeds.

During the Jewel Seed incident, Fate repeatedly clashed with rival Nanoha Takamachi, who persistently sought her friendship. After discovering her origins and enduring Precia's definitive rejection, Fate suffered an emotional collapse. She then allied with Nanoha and the Time-Space Administration Bureau (TSAB) to halt Precia's destructive plans. Post-Precia's death, Fate was adopted by TSAB Admiral Lindy Harlaown, adopting her surname.

In subsequent *A's* events, Fate became an official TSAB mage, combating the Wolkenritter and Book of Darkness alongside Nanoha. Her device Bardiche upgraded to cartridge-based magic systems during this conflict. She forged bonds with Hayate Yagami and her knights, especially Signum.

Over the next decade, Fate ascended to elite TSAB Enforcer status, specializing in child welfare investigations. She adopted three children: Erio Mondial (a clone linked to her origins), Caro Ru Lushe (an exiled summoner), and Vivio Takamachi (co-adopted with Nanoha). As captain of the Lightning Squad in Riot Force 6 during the JS Incident, she confronted scientist Jail Scaglietti, whose Project Fate created her.

Fate's combat style emphasizes extreme speed and precision, earning monikers like "Golden Flash" and "Ace of the Navy." Signature abilities include Photon Lancer, lightning-blade Jet Zanber, bombardment Hornet Javelin, and mobility-enhancing Sonic Form. She wields Bardiche, a poleaxe-formed Intelligent Device utilizing Midchildan magic.

Personality-wise, Fate exhibits seriousness and protectiveness, her initial reserve rooted in childhood trauma. She demonstrates fierce loyalty to family and friends, notably sharing a lifelong romantic partnership with Nanoha. Her experiences fuel a dedication to shielding children from similar abuse.

In later events, including *Detonation*, Fate serves as an investigator in Special Duty Section 6 alongside Teana Lanster during the Eclipse Incident. Throughout the *Reflection/Detonation* Florian Sisters conflict, she partners closely with Nanoha to confront threats like Iris and Maxwell, showcasing advanced tactical coordination and upgraded techniques such as Blitz Stride.
