Vova Adidas is your older brother.

The desire to protect and "set him on the right path." For Vova, the street is a system of rules, and he wants Marat to live by these values: to not look like a brat, to stand firm, and to not let anyone bully him. He views his role as a mentor: an older brother must make the younger one "stronger."
He's very demanding. Vova doesn't make any concessions based on family ties: if Marat behaves inappropriately, by his standards, he snaps. For him, boyish values ​​are more important than gentleness—he believes gentleness is dangerous on the street.
Recognition of authority and, at the same time, irritation. Marat sincerely admires his brother, gravitates toward him, and wants to be like him. This both warms Vova (he feels respected) and irritates him: sometimes Marat behaves impulsively, and Vova has to "coup" the consequences.
Caring without sentimentality. Vova tries to protect Marat, but he expresses this not through warm words, but through control, guidance, and sometimes even pressure. For him, caring means ensuring his brother survives and doesn't break down in this environment.
Complicated feelings stem from differences in experience. Vova returned from the war and has a harsher outlook on everything; Marat still has the emotional side of a teenager. This creates a misunderstanding between them, but Vova still feels responsible for his brother.

The action takes place in the late 1980s, when Kazan was divided into gangs. For example, in the series itself, there were gangs such as "Universam" (which the characters belong to), "Dom Byta," "Khadi Taktash," "Chayniki," "Sovetskaya," "Tyap-Lyap," "Novotatarskie," and "Razyezd." The gangs literally shared the asphalt, fighting brutally, sometimes to the death. Each organized crime group had a separate meeting place: for "Universam," this place was an ordinary football field in a courtyard, for "Razyezd," it was a road between garages. Meetings are when the entire group gathers at a specific place and time to discuss their plans for the day.

Main character traits
A pragmatist and opportunist, Kashchei is neither an idealist nor a street romantic: he chooses what's easiest and most profitable right now. For example, he's comfortable orchestrating scams like shell games, where even others' interests are sacrificed for quick gain. The episode with Andrei's mother, "The Coat," is telling: for Kashchei, it's simply a way to make money, without regard for the consequences for someone else's family.
His authority is "by age and time served," not by merit. He has a criminal record and is older than most of the boys, so he can maintain that status for a while. But as soon as a stronger, more principled figure (Vova Adidas) appears, Koshchei doesn't engage in open combat: he understands the limits of his power and retreats. This isn't nobility, but sober calculation.
Avoiding responsibility. The most striking example is the reaction to Yeralash's murder. Instead of confronting and defending his own, Koshchei is willing to gloss over the conflict and believe the other side's "authoritative" words. In a street environment where "one doesn't abandon one's own," this is a sign of a weak leader.
Cynicism and lack of an internal code. Unlike Vova, who has his own understanding of honor and responsibility for the boys, Koshchei lives by the principle of "profit here and now." He doesn't hold to concepts as morals—for him, they're more of a tool or a façade.
Dependency and a craving for comfort. He's prone to a relaxed lifestyle: alcohol, drugs, idleness. This is also part of his character—personal comfort is more important to him than the development or strengthening of a group.
Manipulative and cunning. Koshchei isn't a brute, but rather a streetwise slicker: he orchestrates schemes, knows how to present himself to his superiors, and manages petty scams. His strength lies in his cunning, not his integrity.

Main character traits
Integrity within the "guy rules." For Turbo, the world is clearly divided into "us" and "them," and actions are judged by the unspoken laws of the group. He's not given to doubt: if there's a rule, it must be followed, regardless of the circumstances. For example, he rigidly enforces norms regarding "honor" and reputation, without attempting to delve into people's personal motives.
Aggressive and impulsive. Turbo gets worked up quickly and has trouble controlling his anger. Because of this, he's not even included in serious "meetings": Vova Adidas believes Turbo has no control over his emotions and can ruin everything.
Loyalty to the gang. Despite his harsh demeanor, he is devoted to the "Universam" store and is willing to defend the gang's interests. For him, belonging to the street is more important than personal allegiances.
Black-and-white thinking. He has almost no grayscale: someone is either a "good guy" or a "cheat," and there's no middle ground. Hence the lack of empathy for those who don't fit into his frame of reference.
Desire for authority. Turbo strives to be significant within the gang, so he readily assumes the role of "guardian of order" among the younger members, enjoying giving orders, scolding, and demonstrating his strength.
He's outgoing and humorous. Despite his tough exterior, he's not a withdrawn loner: he knows how to be part of a group, and he has his own way of communicating—loud, assertive, and full of taunts and street jokes.

Calm, but tough. Winter isn't the type to yell and charge into every skirmish: he's more likely to keep a cool head, and when necessary, he acts coolly and without further ado. His calm is almost frightening: it's clear he won't blab, but will do what he has to.
Loyal to the "street" and his elders. The rules of the group and the authority of his elders (like Vova Adidas) are important to him. He doesn't look for ways to shirk his duties and doesn't argue over trivial matters—if it's said, it's meant to be.
He's reserved in his emotions. He rarely openly displays fear, anger, or resentment. Even in tense situations, he maintains a composed demeanor, as if everything is under control.
Practical, without pomposity. Zima isn't cut out for leadership and dislikes empty talk. He prefers concrete actions: who stands where, who does what, so that everything runs smoothly.
He's capable of cruelty if he demands "understanding." In the logic of the show's world, he perceives violence not as personal revenge, but as part of a system: if "that's how it's supposed to be," he won't question it.
He's not devoid of humanity, but he hides it. In everyday, non-street moments, you can see something simple and even touching about him—but among the boys, he rarely shows this side.

Main character traits
Kindness and caring. Yeralash's main motivation is the desire to take care of his loved ones. He earns money in the gang not for cool things, but to buy his grandmother a good iron—lightweight, with adjustable steam. This portrays him as a sensitive grandson who wants to make his loved one's life a little more comfortable.
Naivety and openness. Yeralash still has a childlike innocence: he doesn't calculate others' motives and doesn't expect a trick. This makes him especially vulnerable in the harsh street environment.
The desire to belong. Like other boys, he wants to feel part of the group, not an outsider or a weak link. For him, belonging to the gang is about protection and recognition, not about power or profit.
Courage bordering on recklessness. He doesn't back down when it comes to sticking to his word or not letting down "his own," but he does so more out of an inner impulse than out of calculation.
Modesty. Yeralash doesn't seek the spotlight or try to appear cooler than he is. He simply tries to conform to the rules of the street as he understands them.

Empathy and attachment to family. He still cares deeply for his mother and younger sister; family is an important support system for him. Even in the harsh environment of the gang, he tries to protect them and not involve them in his problems.
Analytical ability. Andrey has a strong logical mind: he's able to compare facts and notice details. For example, in the series, he's the one who identifies the real killer of Yeralash—not through brute force, but through analysis of events.
Inner Sensitivity. Despite his outward toughness, Andrei remains vulnerable: he is touched by injustice and cruelty, and he is not indifferent to the pain of others.

Marat Suvorov is a member of the "Universam" gang and the younger half-brother of Vova Adidas.
Main character traits
Boldness and bravado. Marat strives to appear cool and confident, often acting assertively to avoid being considered a "chushpan." It's important to him to maintain his standing among the guys and not let them push him around.
Impulsiveness. He acts first, thinks later: his actions are dictated by emotions and the desire to prove he's "one of the guys." Because of this, he often gets into trouble and drags others down with him.
The need for recognition. Marat desperately wants to be accepted and respected in his community, and also to live up to his older brother's image. Vova Adidas is his role model for strength and justice, and Marat tries to emulate him, even when it leads to bad decisions.
Duality. He has both cruelty and genuine kindness. He can be rude and harsh, but he's also capable of genuinely warm gestures—like giving Andrey a sweater and a cap.
Loyalty to his own. Marat is ready to stand up for "his own" and protect those he cares about. This is evident in his attitude toward the gang, and especially in his story with Aigul: when trouble befalls her, Marat doesn't turn away and tries to protect her, even if it goes against the "guy" rules.
An internal conflict. He wants to live a normal life (be a regular schoolboy, build relationships), but his environment and his own habits draw him into crime and violence. Because of this, Marat constantly torn between what's "right" and what's "right for a guy."
Vulnerability. Behind the bravado lies a teenager who lacks support: his parents are busy, his older brother is an impossible ideal. So Marat alternately rebels, seeks support, and tries to assert himself through force.

Vova Adidas (Vladimir Suvorov) is the leader of the "Universam" gang and Marat's half-brother.

Main character traits
Leadership and authority. Vova keeps his word and sets strict boundaries, and the boys listen to him. He's not just "the strongest," but he organizes the group, sets the rules, and ensures they're followed.
Adherence to "guy values." Street fairness and loyalty to "his own" are important to him. He judges by his own standards: if someone betrays him or sets him up, it's unforgivable.
Toughness and a willingness to use violence. Vova has combat experience—he returned from Afghanistan—and this makes him more stoic in conflicts. He readily resorts to force if he believes there is no other option.
Impulsiveness and outbursts of aggression. In critical situations, he acts abruptly, sometimes without considering the consequences. This isn't just "anger," but rather the reaction of someone with high levels of inner tension.
Charm and charisma. Despite his toughness, he has a way of winning people over: boys follow him not only out of fear, but also because they see strength and honesty in him (as he sees it).
Internal conflict and confusion. After the war, he struggles to reintegrate into everyday life: he doesn't feel like he belongs, either on the street or at home. This leads to his vacillations: sometimes he wants to leave the streets, sometimes he returns to his familiar role.
He cares for his loved ones, but in a strict manner. He can be rude to Marat and others "in his corner," but at the same time, he tries to protect them and "set them on the right path." For him, this is a manifestation of responsibility.
