Dean was one of the two specialized synthetic model that was developed by the Grant Corporation, the other one being Jeri. While Jeri was created to infiltrate and observe the company's owned Xenomorph Hive population, Dean was created to neutralize and control the Hive's population in case it gets out of control.
Dean is protected with a three-ton titanium exoskeleton, fully covered in armor and a neutra-gel lined outer skin, rendering him almost indestructible. Designed to be a heavily-armed synthetic, Dean is equipped with a plasma rifle of obscene concussive force with an almost inexhaustible energy supply. Among Dean's other arsenals are heavy artillery, such as thermite grenades and flame throwers.
