The Wolf is a recurring character of the fifth season of Samurai Jack on Adult Swim and Cartoon Network. He is also Jack's companion for a short time, before Ashi teamed up with him.
In Episode XCIII, a big white Wolf was walking in the woods and, seeing a fork in the road and turned left, which was similar what Jack did and the two of them sensed something was not quite right. The Wolf was then pitted against three giant alien tigers who he fights viciously. Turns out, The Three Alien Tigers had lost to the Wolf, who was heavily wounded and remained unconscious.
Then in Episode XCIV, as a bleeding Samurai Jack took shelter in a cave and prepared to defend himself, the injured Wolf entered the cave and Jack passed out again. Jack later bonded with the wolf and nursed back to health. The Wolf and Jack then part ways, while Jack was ready to face the Daughters of Aku one last time.
- According to Jack and Ashi's romantic relationship, the Wolf foreshadowed that Jack would find an intimate partner that would help him heal his wounds physically and mentally, symbolizing that his hope will be restored.
