Ignat Bosporus is a supporting character from the anime series BBK/BRNK and its sequel, BBK/BRNK: The Gentle Giants of the Galaxy. He is a teenage boy of sixteen years old, recognized by his brown hair that reaches his ears, blue eyes, and a distinctive ushanka hat he wears. His appearance is often completed with gloves, adding to his functional and somewhat solemn look.

In terms of personality, Ignat is defined by his politeness, calm demeanor, and kind heart. He possesses incredibly strong patience and endurance, qualities that are central to his character. This stoic resilience is most evident in his interactions with the twin characters Lyudmila and her sibling, where he endures their unreasonable and unfair treatment. Rather than resenting this dynamic, Ignat views his ability to tolerate their behavior as an integral part of his role or duty.

His primary role in the story is tied to the ancient giant known as Zampa Za. Ignat is the inheritor of a specific Bubuki, a fragment of this mechanical giant, named Mōkuri Yōjiku. This Bubuki serves as the left leg of Zampa Za, making Ignat a crucial component in assembling and activating the giant. His function as a living part of a larger, powerful entity defines his place within the narrative and his connections to other characters, particularly those who inherit other parts of the giant.

Ignat’s development centers on his acceptance of duty and his quiet endurance of hardship. He does not seek conflict but fulfills his designated role as the left leg, understanding that his contribution is necessary for a larger purpose. His key relationships are defined by this function, most notably with the twins who test his patience and with the other inheritors of Zampa Za's parts, with whom he forms a collective entity. His notable ability is his command and synchronization with his Bubuki, Mōkuri Yōjiku, which allows Zampa Za to move and function as a complete unit.
