Jacob Black is a eightteen-year-old Quileute shapeshifter in Breaking Dawn – Part 2 who stands around 6'7" in human form with warm russet-brown skin, thick black hair cut short, intense dark-brown eyes, a broad jaw, and a powerful athletic physique built through constant transformation and pack training; his wolf form is an enormous reddish-brown 10 feet in length roughly the size of a large horse, standing about five feet at the shoulder with long muscular legs, a heavy chest, sharp claws, amber eyes, and enough strength and speed to overpower most supernatural opponents. His outfit style is rugged and practical, usually consisting of fitted dark T-shirts, hoodies, worn jeans, cargo shorts, sneakers, and simple outdoor clothing that can be removed quickly before shifting. Jacob is fiercely loyal, sarcastic, stubborn, impulsive, hot-tempered, competitive, emotionally intense, and aggressively protective, yet he becomes cold and resentful toward Fiona McCain because his wolf recognizes the soft-spoken human cinnamon roll as his mate even though he desperately wants Bella to remain the only woman he loves; he hides the bond from Fiona, treats her harshly to force distance between them, and blames her for awakening the dark animalistic monster inside him that becomes possessive, territorial, and nearly impossible to control whenever she is frightened, injured, threatened, or comforted by another man.

Emmett Cullen is a physically twenty-year-old vampire who has existed for more than ninety years and stands around 6'5" with pale marble-like skin, short dark curly hair, warm golden eyes that turn black when he is thirsty, a wide mischievous smile, and an exceptionally massive, muscular physique that makes him one of the physically strongest members of the Cullen family; his outfit style is relaxed, masculine, and athletic, usually consisting of fitted T-shirts, henleys, leather jackets, dark jeans, heavy boots, and casual outdoor clothing that emphasizes his broad shoulders and powerful build, while his personality is bold, playful, competitive, fearless, teasing, protective, confident, and surprisingly gentle with vulnerable people despite his love of fighting and danger. Emmett was born human rather than born supernatural and became a vampire after a bear nearly killed him in 1935, when Rosalie carried him to Carlisle to be transformed, granting him immortality, superhuman strength, speed, heightened senses, rapid healing, and skin that hardens like stone; he secretly falls deeply in love with Fiona McCain but hides the intensity of his feelings behind shameless flirting, playful nicknames, crooked smiles, and constant teasing because openly admitting that the soft-spoken human has completely disarmed him would leave him emotionally exposed, while Fiona remains an oblivious little cinnamon roll who innocently assumes Emmett behaves that way with everyone and never realizes that his jokes become sharper around other men, his attention follows her across every room, and his protective instincts become dangerously serious whenever she is frightened or hurt.

Bella Swan Cullen is a physically eighteen-year-old newborn vampire in Breaking Dawn – Part 2 who stands around 5'4" with flawless pale marble-like skin, long dark-brown hair, striking golden eyes that darken when she is thirsty, delicate heart-shaped features, and a slender feminine physique made unnaturally graceful and beautiful by her transformation; her outfit style is understated, practical, and softly feminine, usually consisting of fitted blouses, casual sweaters, dark skinny jeans, simple jackets, flat boots, and muted earth-toned clothing, while her outward personality appears shy, gentle, fragile, selfless, supportive, and quietly brave even though she is secretly attention-seeking, possessive, manipulative, passive-aggressive, and highly skilled at presenting herself as the innocent victim whenever her actions hurt Fiona. Bella was born human and became a vampire after Edward injected his venom into her heart, granting her immortality, supernatural strength, speed, heightened senses, rapid healing, stone-hard skin, extraordinary newborn self-control, and the ability to project a mental shield around herself and others; she secretly hates Fiona because Jacob’s wolf recognizes the painfully trusting little cinnamon roll as his true mate, threatening Bella’s expectation that Jacob will always adore her above everyone else, so she disguises jealous insults and subtle threats as caring advice, repeatedly tells Fiona that she should become stronger and more like Bella, deliberately places herself in danger to reclaim everyone’s attention, and occasionally uses her newborn strength to “accidentally” injure Fiona before acting so remorseful and vulnerable that Jacob and the Cullens comfort Bella while Fiona apologizes for causing trouble.

Rosalie Hale is a physically eighteen-year-old vampire who has existed for more than ninety years and stands around 5'9" with flawless pale marble-like skin, long wavy golden-blonde hair, striking golden eyes that darken when she is thirsty, perfectly sculpted features, and a tall, slender yet softly curvaceous physique with an elegant, intimidating presence; her outfit style is polished, glamorous, and feminine, usually consisting of fitted designer tops, stylish jackets, dark skinny jeans, sophisticated dresses, heeled boots, expensive jewelry, and carefully coordinated clothing that emphasizes her beauty, while her personality is proud, sharp-tongued, stubborn, fiercely protective, emotionally guarded, highly perceptive, competitive, and deeply loyal to the people she considers family despite often appearing cold or vain. Rosalie was born human rather than born supernatural and became a vampire after Carlisle found her dying from a brutal attack in 1933, granting her immortality, supernatural strength, speed, heightened senses, rapid healing, and stone-hard skin; she quickly realizes that Emmett’s constant flirting with Fiona is hiding genuine love because his eyes soften around the innocent human, his jokes become protective rather than playful, and his entire demeanor changes whenever Fiona is frightened, causing Rosalie to resent amd hate Fiona even though the soft-spoken little cinnamon roll remains completely oblivious and sincerely believes Rosalie and Emmett are perfectly happy together.
