Wolf, played by Ian Whyte, is a character in the film Aliens vs. Predator: Requiem.
After the Predalien survives the crash landing of the Predator scout ship, Wolf responded to the distress signal. The signal took him to Gunnison, Colorado, where Xenomorphs are quickly taking over the city.
Wolf decimates the Xenomorphs in the sewer and the power plant. He eventually tracks the Predalien to the hospital. The two have a climactic battle on the roof, both mortally wounding the other. Just as the two were at a stalemate, the U.S. Government set off a nuclear explosion, killing all the Xenomorphs, humans, the Predalien and Wolf.
