Biography
Early life
Young Jemma.
Jemma was born on 2006 in Volterra, Italy to a human mother Gianna and a vampire father Demetri, both who worked for the Volturi. Gianna died after giving birth to Jemma but Demetri never blamed her for Gianna’s death due to amount of love he has for his daughter. However he didn't know what the outcome would be of a vampire/human hybrid and he was afraid that the Volturi would kill him and Jemma. So he sent her away right after she was born and hasn't seen her since. After the Volturi’s confrontation with the Cullens about Renesmee Cullen who is also half-vampire half-human, Demetri sees that hybrids are no threat to their world. He uses his tracking skills to find Jemma but was unable to find her due to her ability to be untracked.
Jemma spends life on her own with no one, being sad to be separated from her father. She’s also been hearing about the Volturi’s actions and Aro’s motives and Jemma is not happy for how her father ended up. During those times, she meets Raymundo who is also a human/vampire hybrid. The two of them fell in love with one another and became mates.
The two of them met the Romanian coven, the original ruling coven before being dethroned by the Volturi. When Jemma told them of who her father is, the Romanian coven offers to help her reunite with Demetri in exchange of her service to take down the Volturi and she agrees as she joins them along with Raymundo.
Have A Purpose
Jemma pretending to be a lost girl.
In 2025, the Romanian coven commences their plan to take on the Volturi. Jemma arrives in Forks, Washington where the Cullens live. She was found by Jacob Black and Renesmee where Jemma poses as a lost confused girl. They brought her in the Cullen’s house where they took her in. Since then, Jemma has been with the Cullens where she observes them on what they do on their daily lives and then keeps herself quiet in her room. When Lucina Stewart went out on her first date with Bryce Summers, Jemma sneaks out of the Cullen’s house and meets up with Raymundo and returns to the Romanian coven filling them in on what is happening to the Cullens.
Jemma's true character with the Romanian coven.
After Raymundo makes his visits with Cullens, Jemma goes back to Forks but doesn’t return to the Cullens where she was spotted by Bryce’s foster siblings. In April 11, 2026, Jemma was with Raymundo when they met up with Bryce, who is in disguise, where the two are unaware that the Cullens are around to get information on Jemma and Raymundo. A month later after returning to the Romanian coven, they launch the attack on the Volturi with the newborn army’s gifts from Robyn’s copying ability. There, Jemma was reunited with Demetri who turns on the Volturi when Felix tries to attack her. After taking down the Volturi, Aro, Caius, Jane, Alec, Chelsea and many other members except Marcus, the wives and Demetri, were executed and because Chelsea was destroyed, Demetri was freed from the Volturi’s control and left the coven joined by Jemma and Raymundo where they returned to Amun and the Egyptian coven.
Long Live Life
A few years later, Jemma left the Egyptian coven along with Demetri and Raymundo. They then were captured by a half-human half-vampire hybrid named Skai using the sword called IL Mietitore Capacità turning them into metal vampires as he is using them to plot his revenge on Lucien Summers, who was once his friend, for killing Kourtney Collier, a human girl he had feelings for, by killing Luna Snow.
Skai soon started capturing every gifted vampire including the Cullens using them all to kill Lucien. However in the end, the sword is destroyed reversing the effects of those who were captured and Skai is destroyed by the Cullens because of Luna Snow who was able to reverse the effects of the sword because of her human traits and Jemma, Demetri and Raymundo were released from Skai’s control.
Physical appearance
Jemma is a beautiful young girl with pale skin, green eyes from her mother and extremely attractive features. She is five feet and five inches tall with very black hair and due to her ability to have no scent, her appearance makes her look human.
Like all vampire hybrids, she has a rapid beating heart and blood circulating in her body. Her skin glows in the sunlight instead of sparkling allowing her to blend in with humans. Unlike Renesmee and Lucina who feeds off of animal blood, Jemma lives on human blood.
Personality and traits
Jemma is shown to be a shy and scared person as seen when she was introduced to the Cullens but it would be because of the plan she was sticking to. Since living with them, she is very quiet around them. She is also observant meaning she’s curious of what she sees. Jemma also appears to be a good actor when commencing the plan to go to the Cullens.
Powers and abilities
As a vampire hybrid, Jemma displays the same abilities of full vampires, supernatural senses, strength, and speed, but to a lesser degree. Her skin is harder than granite and her bones, including her razor sharp teeth and nails, are nearly unbreakable. Because of her human traits, she can easily blend in with humans and hide her physical abilities. Unlike the male vampire hybrids, Jemma is not venomous.
Sensory void and untrackable
"She can't be tracked. She possessed a gift quite the opposite of her father's."
- ―Edward on Jemma’s gift
As an offspring of her father, Jemma has inherited the opposite of Demetri’s power; while Demetri tracks people by their minds, Jemma can’t be tracked at all. She has no scent and also Lucas can’t use his gift to see her aura giving Jemma the advantage of being untrackable. According to Jalen, he experiences the feeling of being pushed back mentally when trying to catch Jemma’s mind to have access to track her.
Relationships
Jemma is the only daughter of Demetri and Gianna and is the mate of Raymundo.
