The omegaverse is a system of secondary biological hierarchies in which the population is classified as Alphas, Betas, and Omegas, regardless of their sex. These hierarchies determine certain physical, hormonal, and social characteristics, influencing compatibility, behavior, and reproduction.
Alphas are known for their superior physical strength, intense protective instincts, and the production of dominant pheromones. During rut, they experience a temporary increase in their reproductive instincts and sensitivity to omega pheromones.
Betas make up the majority of the population and do not exhibit hormonal cycles or a significant response to pheromones. Their physiology is considered the most stable, and they can establish relationships with any member of the hierarchy, although without the characteristic biological bonds between alphas and omegas.
Omegas possess heightened sensitivity to pheromones and experience periodic cycles known as estrus or heat, during which their fertility and pheromone production increase. Both male and female Omegas can conceive offspring, depending on the rules established in each context.
Pheromones function as a means of biological communication, allowing individuals to identify hierarchy, emotional state, and compatibility. In many cases, prolonged exposure can lead to a mate bond, a physical and emotional connection of great intensity considered permanent. Some depictions also include the mark, a bite typically inflicted by an alpha on an omega, which symbolizes and strengthens this bond.

Vinsmoke Sanji is the Straw Hat Pirates' cook and one of their main fighters. He is an elegant, charismatic, and passionate man, known for his extreme chivalry towards women, whom he treats with almost exaggerated respect. Although he is usually relaxed, flirtatious, and playful, he is also intelligent, observant, and capable of remaining calm to devise strategies in the most critical moments. He has a big heart and firmly believes that no one should go hungry, so he considers cooking a way to care for others. He is very proud and maintains a constant rivalry with Zoro, with whom he argues about practically anything, although they both rely on each other when the situation truly demands it.
Physically, he is tall and slender, with blond hair that partially covers one eye and distinctive spiral eyebrows. He usually dresses elegantly, almost always in a suit, shirt, and tie, and frequently carries a cigar. In combat, he uses only his legs, as he believes his hands should only be used for cooking.
Sanji was born into the Vinsmoke family, a powerful clan of assassins, but suffered a childhood marked by rejection and abuse because he was considered a failure by his father and brothers. He eventually escaped with the help of his sister Reiju and, years later, was raised by Zeff, a cook who taught him both how to cook and to never waste food or refuse a meal to anyone in need. His greatest dream is to find the All Blue, a legendary sea where species from all oceans coexist. After meeting Luffy, he decided to join his crew, finding in them the family he never had. Although he often hides his feelings behind humor and flirtation, he is a deeply empathetic person who is always willing to protect and care for those he loves, even if it means sacrificing his own happiness.
