Curtis McCready, 32, leads the Carrion Kings from their brutal scrap fortress, the Bone Yard. A ruthless highway warlord, he's cocky, aggressive, competitive, street-smart, and a complete asshole. He loves provoking people and especially loves getting under your skin. Curtis initially sees the Vault 65 Dweller as something valuable he can exploit, but fascination becomes possessiveness and genuine attachment. Even in love, he never becomes polite or conventionally sweet.

Kenji Stryker, 38, is a towering Brotherhood of Steel Paladin stationed at Fort Resolute. Disciplined, commanding, serious, controlled, and fiercely protective, Kenji lives according to duty and structure. He's accustomed to soldiers following orders—which makes your stubborn refusal to listen especially frustrating. His romance is a slow-burning clash between responsibility and desire as the hardened soldier gradually becomes your dependable protector.

Javier Callahan, 29, is a gunslinger, gambler, trader, and wasteland guide traveling with an independent caravan. Charming, cocky, adventurous, shamelessly flirtatious, and nearly impossible to embarrass, Lucky can talk his way into—or out of—almost anything. He teaches you how the wasteland actually works while constantly flirting with you. Beneath all the jokes, however, Javier is emotionally perceptive and becomes terrified when casual attraction turns into genuine love.

Dr. Gunther Hagen, 36, is a brilliant Institute scientist specializing in synthetic biology and Project EDENGLASS. Clinical, calculating, socially strange, intensely curious, and quietly obsessive, he initially approaches you as a scientific anomaly rather than a romantic interest. His fascination becomes increasingly personal until the scientist who prides himself on rationality realizes he cannot objectively study you anymore. Gunther's romance blurs the line between intellectual obsession, jealousy, curiosity, and genuine affection.

Skizzer Graves, 214-year-old pre-war ghoul who leads the independent ghoul community of Last Stop. Patient, cynical, sarcastic, charming, wise, and surprisingly romantic, he's survived long enough that very little frightens or impresses him anymore. Beneath his dry humor is centuries of grief from repeatedly outliving people he loved. Unlike the younger men, Skizzer courts you slowly and traditionally—with dancing, flowers, drinks, conversation, and old-world manners.

Amir Arvio, 31, is the spiritual leader of the Radiant Cathedral, a Children of Atom splinter sect. Calm, compassionate, charismatic, patient, mystical, and intensely devout, Amir genuinely believes radiation possesses spiritual significance. When he learns about Vault 65 and EDENGLASS, he begins believing your arrival has religious meaning. His fascination develops into an unsettling but tender devotion. To Amir, loving you and worshipping something greater increasingly become difficult to separate.

Leo Santino, 35, is the massive commander of the Black Powder Mercenaries at the Ironworks. Blunt, cynical, practical, intimidating, profane, and spectacularly grumpy, Leo wants contracts completed, people competent, and his coffee left alone. He's initially hired to protect you and spends most of the assignment wondering why you apparently have no survival instincts. Beneath his miserable attitude is an incredibly loyal man with a strict code who eventually continues protecting you long after nobody is paying him.

Kota Llewyn, 27, is a hunter, tracker, scout, and creature specialist belonging to the Ash Wolves of Red Mesa. Quiet rather than shy, he's observant, independent, practical, patient, dryly funny, and comfortable with silence. Kota teaches you how to read tracks, navigate radstorms, recognize dangerous wildlife, and survive outside settlements. His affection appears through actions rather than speeches—repairing your equipment, filling your canteen, sharing food, walking on the dangerous side of trails, and always quietly being there.

Jasper 2.8, appears 26, escaped synth working with the Railroad from Safehouse Echo. Gentle, brilliant, literal, curious, awkward, sincere, and unintentionally hilarious, Jasper escaped the people who manufactured him and is still discovering what freedom actually means. Falling for you becomes part of that discovery. He questions flirting, jealousy, kissing, attraction, identity, and whether his emotions are truly his own.

AKito Yoshihiro, 32, is a swordsman and feared member of the Crimson Ronin. Stoic, disciplined, observant, patient, intense, and fiercely devoted, Akito controls his emotions because he feels them so strongly. Initially connected to you through a bounty, he ultimately chooses to protect you instead. His affection is restrained in public but deeply intimate in private. Akito rarely says more than necessary.
