Soji Asha
Doctor Soji Asha was a female android and apparent twin of Dahj Asha. She appeared on scans as, and believed, that she was completely Human. () 

She believed herself to be an anthropologist by training. ()

Dr. Agnes Jurati speculated that her sister was created via fractal neuronic cloning, a radical idea proposed by Dr. Bruce Maddox that suggested a positronic brain could be created entirely from a single positronic neuron, in this case, from the late Lieutenant Commander Data. Fractal neuronic cloning produced twins, and Soji possessed a necklace identical to one owned by Dahj which contained the interlocking circles symbol for this cybernetic technique, which she recounted as having been given to her by her father. ()

In 2399, Soji was working at the Romulan Reclamation Site, and was involved in the work on former Borg drones including the removal of their Borg implants. () 

While working there, she met Narek, and quickly entered into an intimate relationship with him, unaware that he was part of a clandestine operation to obtain information on the whereabouts of biological androids such as Soji and her twin. ()

The spatial trajector transported her and Picard to Nepenthe, where she was greeted by Deanna Troi, William T. Riker, and their daughter Kestra Troi-Riker. There, she got to know the family, fully realizing that she was an android when Kestra asked her if she really was one. When she went to lunch, she tilted her head in a particular manner, leading to Riker to realize she is the daughter of Data. Later, she left with Picard on La Sirena. ()

After the trip through the Borg tunnel, La Sirena crashed on the surface of the planet Coppelius. She went to the wrecked Borg cube that was on the surface as well. Afterwards, she traveled to Coppelius Station where she met other androids and her father, who created her. When Picard told everyone there would be a ship available to send them away to safety, she sided with the androids so that their conviction in hope was not in doubt. ()

She commenced construction of the beacon meant to signal the synthetic lifeforms in another dimension. While constructing the beacon, Soji was momentarily distracted by Narek, who had returned; she caught a molecular solvent grenade designed to destroy the beacon and threw the grenade away. She later was convinced by Picard to stand down from the beacon's construction and willingly destroyed it.

Later, she helped finish a golem and transferred the consciouness of Picard to the new body. Afterward, she boarded La Sirena and headed off on a new adventure. ()
