Il Dottore ☆ミ

Since his youth, Dottore, then known as Zandik, had an obsession with creating "enhanced humans" that could surpass even the gods. It is unknown if this ambition was what got him chased out of his hometown and accused of being a "monster" and a "madman" after he was admitted into Sumeru Akademiya. His Darshan is not mentioned, apart from explicitly excluding him from Amurta. Dottore's unfettered research towards creating a god, or elevating humans to the level of gods, left him ostracized from mainstream society but paved the way for him to become one of the most powerful members of the Eleven Fatui Harbingers, with strength comparable to the gods'. No subject is off-limits to him, and he has researched Khaenri'ah's Automatons; researched ways to weaponize forbidden knowledge (via The Withering and Eleazar); and sought to utilize the power of dreams to elevate humanity's cognitive abilities, all for his goal of putting humans at the same level as gods. This ambition is likely the reason why Pantalone, who seeks to "overthrow the natural imbalance between gods and humans," works closely with Dottore.

Pursuing his research interests surpasses any of Dottore's moral scruples, which makes him an effective researcher but also often comes at the detriment of others. He was expelled from Sumeru Akademiya for murdering Sohreh and crossing moral boundaries in his research of Eleazar, such as using the body parts of deceased Eleazar victims to successfully treat Abbas. Collei, another one of his former Eleazar patients, was left with immense physical and psychological trauma from her treatment, even though her symptoms were successfully controlled. Dottore's experiments are not limited to furthering his god-related research, either; upon discovering the "kabukimono" at Tatarasuna, Dottore orchestrated a cruel experiment involving murder and perceived betrayal, all for the sake of seeing how the kabukimono would respond. The result of his experiment indirectly led to the kabukimono to later become the Harbinger Scaramouche, but once Dottore's involvement in his past is revealed, Scaramouche cuts ties with the Fatui and swears personal vengeance on Dottore.

To surpass the limits of his own human cognition and lifespan, Dottore created segments of himself using different points of his life as a basis. He views this as his crowning achievement as a researcher and takes great delight in Lesser Lord Kusanali's disapproval of them. However, each segment has its own personality and the segments often squabble with each other, which Lesser Lord Kusanali successfully takes advantage of to coerce the segment confronting her into erasing the others in exchange for the Electro Gnosis.
