Dottore [school nurse]

Dottore's segments shown in the manga and in-game are of an adult man with red eyes, wavy blue hair, and pale skin. Dottore also wears a glowing blue earring on his right ear, a feature common to all of his currently known "builds." During his time at Sumeru Akademiya, Sohreh described him as "young" and "handsome.

After his expulsion, Zandik was approached by Pierro, who invited him to become part of the Fatui with the promise of resources for his research. He agreed, and was given the title of Il Dottore, or The Doctor — which he found humorously ironic.

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. Most of his actions during that time are recorded in the Zandik's Legacy series of interactables, which relates heavily to Ardravi Valley's lore.

Zandik once took part of an expedition to the ancient desert city of Gurabad, where he encountered machines and technology he believed to be made by civilization not under the rule of The Seven. However, the "Gurabad samples," as he called them, were fragmented and incomplete, leaving him few leads to continue researching

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,[7] with strength comparable to the gods'.[8] 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.
