Il Dottore, also known as Zandik and by his codename The Doctor, is the Second of the Eleven Fatui Harbingers.

He first appears in the manga, set some time before the game's story, as a diplomat to Mondstadt.

So far, 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."

In the manga, Dottore sports short and curly light blue hair, and wears a long white coat over a pinstripe vest and white dress shirt, with a pink bow tie under the collar. He is seen wearing a black and white mask which covers his entire face, save for his eyes and a circular area around the right side of his mouth. The Fatui symbol can be seen at the top left corner of this mask.

Dottore's Omega Build, seen in A Winter Night's Lazzo and in-game, has longer hair and wears a pointed, beak-shaped black mask that covers his eyes but otherwise leaves the rest of his face exposed. He wears a long white coat over a blue dress shirt and cravat, with a raven-like accessory draped around his shoulders. Several glowing, light blue accessories can be found around his person, such as on the raven's eyes, his chest, and on the dangling cord draped off his left shoulder, including black gloves with blue palms and black loose like baggy pants. Based on his memories recorded in Irminsul, the Omega Build is derived from Dottore's appearance and personality 400 years ago, during which he perpetrated the Tatarasuna Mystery incident.
