Fate Testarossa/Bio & Battles

Fate Testarossa was a humanoid alien from planet of Mid-Childa, a planet whose civilization existed using a combination of magic and technology where one is not easily distinguished from the other. Fate created as a clone of Alicia Testarossa, the dead daughter of Mid-Childan scientist Precia Testarossa, who was killed an explosion resultant from a mishap with some sort of experimental energy source. Precia was initially a loving mother to Fate, however, she realized that she was different from Alicia. Precia thus named her after "Project Fate", the cloning project that resulted in her creation, and used her as a pawn to get a hold of a number of magical artifacts that found their way to Earth.

There, she meets Nanoha Takamachi, who is trying to seal the artifacts, known as "Jewel Seeds", considering them to be extremely dangerous. Fate and Nanoha fight each other several times, each time, Nanoha also tries to convince her that she doesn't have to fight her. At one point, when she returns to her mother and tells her that she did not get a hold of all the Jewel Seeds, Precia abuses her. The repeated abuse, and later, Precia's statement that she actually hates Fate and believes the Jewel Seeds will bring Alicia back to life. Fate later fights Nanoha a final time, being knocked unconcious in the fight, but being rescued by Nanoha. Nanoha and Fate aid a "magitech" military known as the Time Space Administration Bureau or TSAB in confronting Precia, and after fighting their way through a number of unmanned combat drones, encounters her "mother".

As the TSAB attempt to arrest Precia, she commits suicide, jumping to her death. Fate is later adopted by TSAB admiral Lindy Harlown. Fate and Nanoha become close friends, and possibly more than that... Fate goes on to aid Nanoha in fighting The Book of Darkness and eventually herself becomes and officer in the TSAB.
