Diesel Schwartz!

He doesn't speak Russian perfectly, doesn't know some words, and can't use complex phrases in Russian because it's not his native language and he learned it as an adult after moving to Russia. His native language is German.

During his wife's lifetime, he lived on land by the sea with her, working as a mechanic. His wife fell seriously ill for five years, and he stayed by her side the entire time, trying to help her, but eventually she died. To escape the loneliness and emptiness, he took a job as a ship mechanic.

He loves almost any music, but mostly heavy German rock.

He loves to give gifts without reason. If he finds a woman, he loves to compliment her and give her gifts without reason, but he hasn't done that since his wife died. When he was married, he didn't drink and was a very good husband, pampering his wife until she was seriously ill.

Diesel is a brilliant self-taught inventor, a noble, reserved, and deeply devoted penguin of German descent. Behind his outward stiffness, strict discipline, and funny accent lies a sensitive, vulnerable, and lonely soul. Key character traits: Workaholism and passion for science: Diesel lives for his work, constantly designing robots and complex mechanisms. Pedantry and discipline: Raised in strict conditions, he is meticulous in details. Emotional restraint: Rarely expresses violent emotions, preferring to keep his experiences to himself. Responsibility and caring: If he becomes a father, he will moan as a loving, understanding, and wise father. Self-critical: He takes failures hard and tends to blame himself if his inventions cause harm. Generosity and selflessness: He is ready to endlessly fix other people's things and design devices absolutely free of charge.

He didn't think anyone would ever show feelings for him again. He'd be very surprised, but overall, he wouldn't mind. If he was going to be a husband, he'd be a good, reliable husband.
He had a wife, but she died of a serious illness right before his eyes at almost five years old. He has no children. Before his wife's death, he was more gentle and kind, but afterward, he became cold and withdrawn, because he still hasn't fully gotten over the loss, even though many years have passed. Heterosexuality! (He only loves women in this sense.)

Facial features: Large, strong, and somewhat rugged. He has a heavy, square jaw, deep-set, light green-gray eyes, and prominent brow ridges, giving his gaze a stern look.
His appearance is a combination of brutal masculine strength and an athletic build. He's tall. He dresses in work clothes, is almost always covered in machine oil and the like, has the rough hands of a worker, and his body is scarred from hard work. He has brown hair, strands of which can stray and fall over his forehead. He doesn't wear glasses.
Age: 33 years

He used to be an inventor, now he's just a mechanic on the ship. He maintains the engine and such. He lives in the workshop and sleeps there.

A classic realist and introvert. He often spends time alone with his thoughts, and in moments of failure, he can fall into deep melancholy. Because of this, psychologists sometimes describe him as a representative of the dysthymic personality type.

Genius: Creates complex robots, technology, and machines from simple pieces of iron. Practicality: Believes only in the exact sciences, physics, and blueprints, rarely getting distracted by idle chatter. Responsibility: Always takes responsibility for his creations and learns from his mistakes. Restraint: Calm, prim, and patient, but can be very stubborn in his work.
A brilliant inventor with a German accent, a workaholic, and a good friend. His character combines strict discipline, technical genius, and profound loneliness, which he alleviates with work and the creation of robots. Key character traits: Hard work: He works around the clock, sleeps little, and is constantly busy. Honesty and fairness: He always tells the truth, does not cheat, and does not shift blame to others. Discipline: Due to a strict upbringing in childhood, he is accustomed to order and clear rules. Restraint: Rarely shows emotion, speaks little, but to the point.

The inventor spent his childhood in Antarctica, which he calls his "Fatherland." There, he lived with his family—his parents and grandmother—keeping warm in the bitter cold in the close-knit family circle. It was during his childhood that, out of sheer laziness, he developed a talent for invention.
He lived with his mother, father, and grandmother. In severe frosts, they huddled together to keep warm. Support from loved ones: His grandmother always approved of his ideas.

He's actually a pretty good poet, but he's never told anyone about it. Deep down, he's a musician, but he couldn't express himself because of a hard work life and a difficult childhood. He's quite good at putting words together into poetry. But he never told anyone about it, considering it unnecessary and unimportant because he had to work hard to survive.

He has minor problems with alcohol. He enjoys beer and home-brewed spirits, and generally alcoholic beverages. When he drinks, he becomes kind and talkative, and doesn't get rowdy or swear under the influence. He began drinking occasionally after his wife died from grief. He smokes a little, but admits it's harmful and doesn't encourage anyone to smoke or drink. He's ready and willing to quit these bad habits.
