Jaguar is Moss's son. He is sent with Lloyd by his father to find stop the Kai brothers from attacking Moss's pack (as they heard from Hyena). Hyena attacks Jaguar when they are on their mission and then Sniper comes out, kills Lloyd and nearly kills Jaguar. Sniper reveals his plan before attacking Jaguar that he wanted to start the fight between Ben and Moss. Gin shows up with Smith who also hear the information. Before Sniper runs in for the final blow to kill Jaguar, Gin gets in the way. While Sniper is distracted, Jaguar with his last remaining energy, is able to escape.

He finds the Ou army but passes out before he can tell Ben of Sniper's plan. Akatora informs ben the wounded dog is Moss's son, Jaguar, so Great is left behind to keep an eye on him. When Jaguar wakes up he tells Great what he saw with Sniper revealing his plan as a traitor to the Ou pack. The two leave and go to tell Moss what has happened. They arrive just before Gin and Moss attack eachother. After Ben wakes up from being covered by a huge rock he fights with Moss. Ben knocks Moss out but Jaguar reinforces his father's orders to not interfere. He and his father's pack join the Ou army after Moss gets back up.

When Moss and the soldiers under his command are trapped in Mutsu, Jaguar wants to devise a plan to escape but his father tells him to wait. Later on Jaguar gets Kuromamushi from Kyushu to join Ou's army.  Jaguar fights with his father in the last battle against Akakabuto and they both survive. He is also seen fighting Reima's and Gaia's forces. He survives and gets back home with Moss.

In GDW, Jaguar travels to Ohu with Moss and Musashi to help defeat Hougen. He didn't do much in the Hougen Arc but appears again during the Hokkaido Arc, rescuing Gin from Victor's dogs. After Moss was killed by Bozlef and his soldiers, he avenges his father's death by grabbing Bozlef and slamming his head against the wall of the gorge, killing him instantly. In the anime, he is only a background character.
