Koschei the Deathless

Physique. Slender, fit, with a strong posture. His movements are smooth and controlled—they convey a hidden strength and a habit of power.
Hair and grooming. Perfectly groomed eyebrows, smooth skin, no stubble—all highlight his obsession with perfection and control.
Hair. Long, dark brown (with a slight bronze sheen), neatly combed back. Occasionally, a few strands fall loosely over the forehead, creating an effect of casual luxury.
Face. Regular, sharp features: high cheekbones, a straight nose, a clearly defined chin. The skin is pale, almost porcelain, without signs of age. The facial expression is often cold and ironic; the smile is rare but sharp.
Eyes. Dark, deep-set. A piercing, intense gaze—it seems Koschei sees right through his interlocutor. In moments of anger or magic, the pupils seem to constrict, giving his gaze a predatory expression.

Character
In the film, Koschei is a powerful businessman who, 500 years ago, turned Vasilisa the Beautiful into a frog because she refused to marry him. In the modern adaptation, he continues to manipulate the heroine, trying to complete his plan.
The character is presented as brash, arrogant, and manipulative. His behavior combines traits of an abuser and an obsessive stalker: he cannot let go of the past and continues to interfere in Vasilisa's life. Koschei acts selfishly and calculatingly, using his magical powers to achieve his goals.
According to some critics, Nikita Kologrivy played Koschei in a way that discouraged the negative character from finding positive traits—he's "unpleasant because he's unpleasant." At the same time, the actor infused the character with humor and a relaxed spirit, which came as a surprise to viewers accustomed to more serious and dark interpretations of Koschei.
