The Ghost Wolf of Dreams is a supporting character in the 2020 live-action adaptation of Jack London's The Call of the Wild. He is a mysterious black wolf who aids Buck on his quest to become wild.
He was portrayed by Terry Notary.
During the night after Buck's first sledding attempt, he comes across the Ghost Wolf sleeping on a rock. Buck approaches the Ghost Wolf until he wakes up and stands on his feet. The Ghost Wolf towers over Buck and he backs away in fear. When Buck accidentally wakes up Pike, the Ghost Wolf disappears.
Throughout the journey to Dawson, Buck finally becomes an experienced and confident sled dog. One day, when Francoise falls into a frozen lake, Buck jumps in to rescue her. While trying to find a way out, the Ghost Wolf appears and stands above him. Buck manages to break out of the ice and get Francoise to safety, but Buck gets pulled away by the current. Perrault tries to save him, but Buck manages to escape and Perrault rejoices.
The following night, Buck battles the ruthless lead dog, Spitz and is knocked unconscious. However, Sol-leks encourages him to get up and the Ghost Wolf appears as he encourages Buck to get Spitz. Buck gets up and manages to defeat Spitz, who wanders off into the wilderness, never to return.
The next day, Buck takes the lead and they head out. However, Perrault accidentally causes an avalanche and he orders Buck to turn left, but the Ghost Wolf appears standing on top of a cave, so Buck and the team rush over there. Buck and the team manage to escape the avalanche and finally make it to Dawson.
The Ghost Wolf later makes a brief appearance as he watches Buck from a hill after he found his place in the wild as he joined a pack of wolves and mated with a female white wolf named Carol, who gave birth to a litter of pups named Bruno and Lou.
