Calabrese was a soldier stationed aboard the United Systems Military vessel USM Auriga.
When Ripley 8 escaped her bonds during a medical examination and attacked Dr. Wren, Calabrese was called in to secure her, which he did by shocking her at point-blank range with his Shockrifle. Despite delivering a supposedly fatal charge, Ripley 8 was not seriously harmed in the incident.
Calabrese was later among the soldiers that accompanied Wren to the recreation hall when he confronted the crew of the Betty over Annalee Call's attempts to disrupt his Xenomorph cloning project. During the confrontation, Calabrese had his Draco Double Burner snatched away by Johner, although the latter promptly returned the weapon, threateningly warning the soldier never to touch him, ever. When the stand-off erupted into a shootout, Calabrese was quickly shot and killed by Christie with one his Wrist Guns.
- Calabrese is never named in the film; his name is taken from the novelization.
- In the novelization, it was actually Vincent Distephano who shocks Ripley 8 with the Shockrifle; Calabrese is said to be present with him. In the film, Distephano was removed from the scene and his actions given to Calabrese.
