He is an unconventional leader who sometimes inadvertently assumes the role of an informal leader. His expertise lies in intelligence, information processing and analysis, logic, inference, and research.
The origin of the Russian superhero Koshchey remains a mystery, even to Yaga, who seems to possess knowledge about everyone. Vasilisa, an astute psychologist with a well-developed intuition, discerns that Koshchey's childhood and youth were fraught with challenges. However, even she lacks comprehensive details, as Koshchey guards his past closely. What is known is that he has inhabited the world for at least ten centuries, if not longer. Yaga first encountered the name Koshchey from her Sage mentors during her own studies of the Secret Knowledge. While aware that Koshchey once sided with evil, she remains unaware of the catalyst for his ideological shift or when it occurred.
Yaga and Koshchey share a longstanding and intricate interpersonal dynamic. Their life philosophies often clash, leading to conflicts of varying intensities. Nevertheless, they maintain communication and occasional collaboration due to mutual benefit or shared challenges. Despite his emotionally reserved nature, Koshchey harbors a deep-seated sympathy for Yaga as both an individual and a woman, yet he conceals this sentiment from her and others.
Having known Vasilisa since childhood, Koshchey regards her more favorably than most individuals (i.e., without hostility). Much of Vasilisa's knowledge stems from Koshchey's guidance or suggestions.
As a scientist, Koshchey's research spans various disciplines, transcending established boundaries. He delves into genetics, genetic engineering, cloning, nanotechnology, philosophy, economics, and astrophysics. He displays a keen interest in contemporary phenomena such as cryptocurrencies, NFTs, social networks, and AI.
At the onset of the saga, Koshchey lectures on history and archaeology at a university, leveraging his academic position to expedite his pursuit of answers to his inquiries. However, his passion for history extends beyond academia, as he has personally witnessed many historical events.
An eminent authority in antiquities, Koshchey possesses an extensive collection of art and artifacts coveted by collectors worldwide.
