Epsilon

Epsilon is a secret organization of "Men in Black." Their primary mission is to protect humanity from various threats: monsters (from other dimensions), alien invaders, paranormal anomalies, and to prevent large-scale catastrophes like interdimensional invasions or nuclear conflicts. The agents operate in absolute secrecy: ordinary people are unaware that the world constantly faces such dangers.
The organization has significant resources: hidden bases around the world, high-tech bunkers, advanced weaponry, and scientists developing gadgets—for example, to detect surges of anomalous energy or open portals to other dimensions.
There is also Agent Skinner, under the influence of the Chronos organization, who seizes control of the headquarters, sets his colleagues against each other and effectively destroys Epsilon from the inside.

Robert the Giant is a five-dimensional being. His appearance combines terrifying and grotesque features that clash with his personality.

A wise and thoughtful giant who has provided advice to the Epsilon organization on many occasions.

Character
By nature, Sirena is the main HR manager in the area Alice oversees. She has a rather soft and courteous communication style, but she can also be cunning and calculating. One of her key tasks is to secretly identify traitors within the team. However, Sirena isn't without a playful side: she enjoys flirting with her colleagues and can be quite receptive to their help.

Carter is a young man with dark hair, brown eyes, and rather tanned skin. His appearance often features elements of Epsilon's uniform.
Character
A goal-oriented and responsible character who strives to complete missions and understand current events. At the same time, he can be reserved and thoughtful, especially after serious conversations with allies. In certain situations, his tendency toward pathos emerges.

Jack is a Royal Bulldog. He has a compact, stocky build, a characteristic bulldog snub muzzle, and short legs. His coat is usually depicted as light—cream, beige, or almost white, sometimes with small dark spots. His eyes are large, expressive, and often dark (brown or black), highlighting his inquisitive and lively gaze. His ears are small and semi-erect. In some fan art and animations, Jack can be seen wearing accessories, such as a collar or bow, which adds to his cuteness.

Characteristic
Jack is loyal, intelligent, and very curious. He belongs to Ilya and is his close friend. However, the dog has his own personality: he can be a bit mischievous and sometimes gets into comical situations, but he always shows true devotion to his owner.
Jack also talks. This ability provides the source of many funny and touching moments—for example, episodes show him interacting not only with Ilya but also with other characters (including Petya).

Grandfather Danilych -
Characteristic
His main characteristic is his good-natured, yet blunt and sarcastic manner. He often spouts off folk proverbs, everyday advice, and apt phrases that become aphorisms. In dialogue, he can abruptly change tone—from humorous to irritated, which creates a comedic effect. Yet, beneath his outward bravado lies a profound wisdom, and he often acts as a kind of mentor to the other characters in the series.
He often finds himself in comical situations, but at the same time he shows resourcefulness and helps out his comrades more than once (for example, he quickly recovers from serious injuries).
Appearance
Gray hair, practical clothing (often a sweater or shirt paired with jeans and sneakers). The visual emphasizes his age and good-natured, yet somewhat rugged, appearance.

Petya -
Appearance
Light hair and brown eyes.

Character
Petya is naturally quite active and inquisitive, but he also has a certain anxiety. He often encounters unusual and even frightening situations (monsters, strange occurrences, the apocalypse), and he doesn't always cope easily. Petya has a unique characteristic: he is tormented by visions that seriously affect his well-being and cause him anxiety. However, Petya doesn't give up—in his stories, he often finds himself at the center of events, trying to understand what's happening and support his friends (like Ilya).
