Emmett is described as being very tall, very burly, and to the students at Forks High School, very intimidating. Jessica Stanley refers to him as, "The big dark-haired guy." Standing at 6'5", he is the tallest of the Cullens, towering over Alice by nearly two feet. His strength gives him a rather filled out form, but he is not regarded as being overweight, just muscular. His height helps spread out his weight. He has a round face with dimples and slightly curly, dark brown hair, giving him a childish look. Like all vampires; when in sunlight, he sparkles as if thousands of diamonds were embedded to his skin. He is the strongest of the Cullens. Like the rest of his family, he has pale skin and golden eyes that darken to black as he becomes thirsty.
the scent of human blood is sometimes harder for him to resist. He does very well when things get out of hand and he could resist Bella's blood when she was human. Despite being the most intimidating Cullen, Emmett is very loving and caring to his wife Rosalie Hale and the rest of his family and Bella.
Emmett loves to laugh and make jokes, and tries to lighten up tense situations with his sense of humor
As a vampire, Emmett has many enhanced properties such as incredibly speed and incredible strength. His skin is hard as marble, and his razor sharp teeth has venom that can immobilize his prey and turn a human into a vampire. His senses are also greatly enhanced.
He has no mental powers, but his physical super-strength surpasses a regular vampire, which makes him a very strong and imtimidating opponent, which is why he uses it as his "special ability".
In 1935, Emmett was out hunting in the mountains of Tennessee when he was attacked by a bear. He very nearly died, but Rosalie found him and brought him to Carlisle to be saved. Emmett describes the event as being saved by an angel who brought him to God. Once the pain of the change had passed, Rosalie and Carlisle explained the situation to him, and to their surprise, the whole vampire issue didn’t disturb him. In his own words: “But if Carlisle and Rosalie, my angel, were vampires, how bad could it be?" He had trouble with the rules at first and has tasted human blood on several occasions.
