From BloodChosen. He appears as a man in Blood, but a woman in Blood II (after her resurrection), giving no explanation other than "it's a long story". The male version appears as a bald Anglo-Saxon man with a brown tunic but the female version appears as an an African-American Creole with a thick cajun accent. She was voiced by Lani Minella in Blood II: The Chosen (also the voice of Ophelia Price). She is easily the strongest of the Chosen and even towers over Caleb in size, but she lacks the speed and stealth to be as effective a warrior as Caleb. Gabriella has a tendency to crack "Yo Mama" jokes when left alone.
Note: Due to the little back story Gabriel has in Blood, the rest of this article will refer to the subject as female.
 Early Years
Gabriella was born out of vengeance and groomed to be a warrior since birth. Her life was steeped in ritual, tradition, and war and her bloodlust was insatiable. This made her a perfect fit for the Cabal, though how she joined is unknown. Her early life was not completely violent though, as "papa" would always take her to the freak show every year to see JoJo. Eventually her prowess, skill and service to the Cabal lead to her being proclaimed one of Tchernobog's elite Chosen.
 Betrayal and Death
Sometime between 1871 and 1928, Tchernobog summoned the four Chosen to the Hall of the Epiphany, Tchernobog's chamber. Instead of giving them orders as they thought, Tchernobog told them that they had failed him and that he disavows them all. The four were stunned as Tchernobog sent his lieutenants to take the Chosen one by one. Shial descended from a thread of silk and took Gabriel off into the darkness. At some point Shial wrapped Gabriel in a cocoon and took her to him lair under the arctic circle. Later, Caleb found him, killed Shial, and removed Gabriel's heart from the cocoon, which he ate or drank (his back is turned to the camera) in order to increase his powers to face Tchernobog. Caleb does however apologize to Gabriel for this before he begins.
Gabriella is first seen when she is summoned out of the portal by the Singularity Generator in the Lafayette Museum of Antiquities, in 2028 (from here on is her gender and name change offical). Her coming seems to be a surprise to Gideon and the Mad Scientist, even though he knows the Chosen can be resurrected by this means, since he has Ophelia in his temple. Caleb acts cold towards Gabriella, who says that she needs to go with him to find out what is happening. Caleb refuses, saying that she is "not [his] type". Gabriella challenges Caleb's authority and ability to solve the problem.
 The Nightmare
During their journey back home, the four Chosen stop at a campfire and tell ghost stories. Gabriella tells of the time she had to stay in a "spooky mansion" overnight.
