Ayana Hamontree is a former Umbrella Researcher who now leads her own B.O.W.-dealing organization, Hamontree-Barnes Biotechnologies.
During the Raccoon City Incident, Ayana Hamontree was a young Umbrella researcher. She and several fellow researchers successfully escaped the city and quit Umbrella, forming their own group in developing bio organic weapons. They began engineering their own virus, and then tested it on several kidnapped men. Within hours, the subjects mutated into zombies. Hamontree volunteered herself interact with these zombies. For each test, Hamontree was placed in an observation room with a zombie. After spending a few minutes with the zombie, the zombie would be led back into its cell while Hamontree left the room. She was able to order each zombie to perform simple tasks, and none expressed any interest in eating her.
Hamontree's fellow researchers, however, were ambitious to see what these zombie would do next to a human for extended periods of time. During one of the tests, they all agreed, without Hamontree's consent, to lock her in the room while releasing all zombies from their cells. Hamontree, of course, protested, but there was nothing she could do. The zombies still showed no interest in her after several hours. Eventually reassuring herself that they were harmless, Hamontree fell asleep, having been trapped for the entire day. In a few minutes, a zombie woke Hamontree when he started to rape her. The other zombies soon followed. When each zombie was finished mating, he returned to his typical behavior. Hamontree's fellow researchers then brought her out of the room and ran tests, discovering that she was pregnant. They forced her to keep whatever was in her womb.
Over the course of two weeks, Hamontree grew increasingly hungry, eating more than twice the amount she normally would for each meal. This was due to the rapid growth of the creature inside her womb. At the end of the two weeks, Hamontree gave birth to what looked like a large, armored maggot. The creature chewed away the umbilical cord and began feeding on Hamontree's breastmilk. A week after its birth, the monster entered its pupa stage, but erupted from its cocoon in just thirty seconds. Hamontree was able to feel the mind of the creature and soon discovered that she could control it at will. She used it to kill one researcher, and then used this fear to take over the entire research group. Being the one in power, Hamontree named the B.O.W.-dealing organization, Hamontree Biotechnologies, and named the new B.O.W., Armisael. As the only female of Hamontree Biotechnologies, she continued to mate with zombies to make more Armisael, using the B.O.W.s as her personal military.
Later on, Hamontree Biotechnologies developed a mass-produced variant that would be created by impregnating a woman with an artificially-inseminated egg. Hamontree's accomplishments soon caught the attention of Adam Barnes, the young leader of a criminal organization. Barnes' father had been killed by the bioterrorist group Za'afiel, and he intended to avenge his late father. Having been trained thoroughly as the former heir of his father's empire, Barnes offered to fund Hamontree, who saw Za'afiel as a threat to her work. This alliance became known as Hamontree-Barnes Biotechnologies, and its subsequent military force formed from mercenaries became known as the Hamontree-Barnes Biotechnologies Security Forces.
