Description
Nathan Seymore, known by the superhero alias Fire Emblem, is a professional NEXT active in the city of Stern Bild and serves as a supporting hero within the main cast of the Tiger & Bunny franchise. They are also the president of their own sponsoring company, Helios Energy, a major energy conglomerate that ranks among the wealthiest entities in Stern Bild. As Fire Emblem, Nathan possesses pyrokinesis, the ability to generate and manipulate fire with a high degree of control, shaping flames into various forms and intensities for combat, crowd control, or dramatic effect. Their hero costume incorporates advertising for their sponsor, and they are often seen driving a custom race car equipped with specialized ball bearings.

Nathan is characterized by a flamboyant and androgynous appearance, marked by short pink hair, purple eyes, and a confident, expressive demeanor that blends high-fashion aesthetics with a bold, unapologetic personality. They are highly intelligent and observant, often using their platform to challenge traditional norms and express their individuality. Despite the pressures of the corporate-sponsored hero system, Nathan maintains a strong sense of self and a commitment to authenticity. Their personality is outgoing, passionate, and adventurous, though they can also be narcissistic at times.

A central aspect of Nathan's identity is their gender and sexual orientation, frequently identified as non‑binary and gay, and they are open about their attractions, often playfully flirting with male heroes. Their backstory, explored in the film Tiger & Bunny: The Rising, reveals a painful childhood: they were ostracized by peers and family for their feminine interests and attraction to men. This rejection left deep scars, but it also forged a resilient, self‑assured adult who refuses to be bound by binary expectations. A key quote from the film encapsulates their philosophy: they reject the idea that courage belongs only to men and love only to women, declaring that those who encompass both are invincible. Nathan’s personal motto is that failure is part of the fee paid to live a fulfilling life, and their future goals include increasing company sales to make donations to disadvantaged children and building a happy family with a lover.

Within the hero team, Nathan acts as a social catalyst, often speaking their mind and challenging the status quo. They share significant interactions with fellow heroes Kotetsu Kaburagi (Wild Tiger) and Barnaby Brooks Jr., and they display a nurturing, almost maternal side toward younger heroes like Blue Rose and Dragon Kid. Nathan’s role is primarily supportive, providing tactical firepower and distinct social dynamics that keep the ensemble engaging. Throughout the original anime series, the films The Beginning and The Rising, and the sequel series Tiger & Bunny 2, Nathan evolves from a seemingly carefree eccentric into a character whose flamboyance masks a history of pain and whose openness becomes a source of strength. They are one of the richest heroes in Stern Bild, yet they leverage their wealth and influence for altruistic ends, demonstrating a motivation rooted in overcoming their own past rejection and helping others.
