Species III

A university biochemist who secretly raises Eve's child, Sara, while pursuing aggressive research into alien DNA. He returns to teaching while also pushing experimental work that blurs ethical lines. Abbot is driven, protective of Sara, and morally conflicted as government interests press for results.

An alien being whose pregnancy births Sara and whose genetic material seeds the hybrid lineage. She dies during the delivery, becoming the origin of Sara's extraordinary biology. Eve's legacy frames the central conflict around hybrid survival and the consequences of crossing species lines.

An alien creature who ambushes the human rescuers, ages dramatically, and fiercely pursues Sara. Portus embodies the predatory peril of the hybrids and the urgency of containing the hybrid threat. His presence accelerates the plot and deepens the mystery of the hybrids’ fate.

The daughter of Eve and Portus, Sara grows into a capable and intelligent hybrid who drives much of the action. She navigates interactions with humans and other half-breeds, seeks a mate, and becomes a central figure in preserving her species. Sara's choices shape the ethical and existential stakes of the story.

A university student who collaborates with Abbot to refine alien DNA, becoming entangled in the scheme to save the hybrids. He helps devise strategies and ultimately faces the moral complexities of scientific progress. Dean's decisions influence whether Sara finds a mate and whether the project succeeds.

Dean's roommate and a curious observer who uncovers Amelia's dangerous activities. He is drawn into the hybrid saga as plans unfold, eventually becoming a hostage figure who influences the lab’s dynamics. Hastings's fate intersects with the broader attempt to manipulate alien biology.

Another half-breed who uses a dating website to lure biochemists and is involved in kidnapping Hastings. She aids Sara in pursuing genetic experiments but ultimately meets a fatal fate in the core, illustrating the perilous nature of the hybrids' power.

A high-level scientist who attempts to assert control through power and intimidation, including an attempted assault on Sara. He is killed by Sara, highlighting the dangerous clash between predatory ambition and the hybrids' resilience.

A government agent who monitors the pregnancy and the project, coordinating autopsy efforts and working to safeguard Hastings. He plays a crucial role in the containment and strategic decisions around the hybrids' survival.
