- "I heard his wolf killed a dozen men and as many horses."
- ―Leo Lefford
Grey Wind was adopted as a pup with the rest of the Stark direwolves when Eddard Stark and his entourage came upon the pups and their deceased mother. At the request of Jon Snow, the pups were spared and each Stark child adopted one as their own. Robb names his direwolf Grey Wind.
When Tyrion Lannister appears before Robb Stark at Winterfell to present him with plans for a custom saddle which will allow the crippled Bran Stark to ride a horse, Grey Wind is under the table at Robb's feet watching their visitor intently as he presents the plans to Bran.Lord Greatjon Umber draws his sword when Robb refuses to give him command of the Northern army's vanguard, a tantamount to a threat. Grey Wind jumps over the table. He latches on to Umber and bites off two of his fingers. Jaime Lannister at camp, Grey Wind slowly emerges. Grey Wind has grown larger and stands protectively next to Robb, who caresses his back. After Robb leaves, Grey Wind inches closer to Jaime and taunts him with a snap, before leaving to rejoin his master.
Grey Wind plays a decisive role in the Battle of Oxcross. The direwolf sneaks into the Lannisters' camp and frightens their horses, as well as killing several sentries. Without their horses the Lannister army is easily slaughtered as they are roused from sleep by Stark cavalry. Such an impression is made on Lannister forces that terrified rumors spread in King's Landing that Robb attacked the Lannister camp using an entire army of wolves.
Grey Wind accompanies Robb's host to the Twins for the wedding of Edmure Tully and Roslin Frey, though he's placed inside a kennel. Grey Wind grows restless, having sensed the impending betrayal of the members of House Frey. When the Frey and Bolton men turn on the Starks, Grey Wind is shot several times by Frey crossbowmen before Arya Stark can release him. He succumbs to his injuries just after making eye contact with Arya.
Later, as the Frey and Bolton men continue massacring the Northern army, both Grey Wind and Robb's corpses are decapitated, with Grey Wind's head sewn onto Robb's headless body and paraded atop a horse around the Twins as final act of mockery and desecration to the late King in the North.

In the books
In the A Song of Ice and Fire novels Grey Wind is arguably the most disciplined of the six pups; he follows Robb's commands almost to the letter, mirroring how Robb is arguably Ned's most understanding and disciplined child, very much his father's son. It is stated that he received his name because Robb felt that he ran so fast that he seemed like just a blur, a "grey wind" moving over the fields. He is colored smokey grey, with yellow eyes. He can detect danger, and sense whether people are friends or foes.
After Robb marries Jeyne Westerling, Grey Wind acts restlessly in her vicinity, as well as near her mother Lady Sybell Spicer and uncle Ser Rolph Spicer (all of whom collaborate with the Lannisters), causing Catelyn Stark to distrust them and urge Robb to send Ser Rolph away. Robb, however, believes Grey Wind has grown violent because of the war and has the wolf put away, as he has also lost his faith in Grey Wind due to the news of his brothers' deaths. Grey Wind is friendly toward Jeyne's sister Raynald, who is not involved in the scheme against the Starks.
On the way to the Twins to celebrate Edmure's wedding, Ryman Frey and his three sons welcome the Starks. Grey Wind senses that they mean ill and acts menacely toward them, frightening their horses and causing Petyr "Pimple" to fall to the ground. Morever, at the middle of the drawbridge, Grey Wind howls at the portcullis and bares his teeth, and Robb can barely calm him down.
Unfortunately, the Starks fail to understand the significance of Grey Wind's aggressive behavior, and the above mentioned incident provides Lord Frey a convenient excuse to demand that Grey Wind will be kept at the kennels. Robb does not like the idea of being separated from his direwolf but complies, determined to appease Lord Frey at any matter. It is doubtful that the direwolf's presence at the wedding hall could have changed the outcome, but it might have made the conspirators' victory more costly.
During the Red Wedding itself, as the massacre is taking place, Grey Wind is released by Raynald, who was presumably killed for his attempt to save the direwolf (he was shot by two arrows, jumped into the river, and his body was never found). Allegedly, the beast kills four Frey wolfhounds and tears the arm off of the kennelmaster, even while being shot repeatedly by crossbowmen.
Similarly to the show, the Freys sew Grey Wind's head to Robb's corpse and nail a crown on his ears as an additional insult to the Starks, but it is done off-screen.
In the books, Arya never witnesses Grey Wind's death or her brother's desecrated corpse with his head sewn on. This was likely written to provide a familiar POV character to the desecration - which in the novels is only described by Salladhor Saan to Stannis, since the Red Wedding is a chapter from Catelyn's POV which ends when Catelyn is killed.
