Wulfgar, son of Beornegar, is the barbarian hero of Icewind Dale in the Forgotten Realms campaign setting, and one of the Companions of the Hall along with Drizzt Do'Urden, Catti-brie, Regis the halfling, and Bruenor Battlehammer.

Wulfgar was originally planned to be the protagonist of Salvatore's first novel series, The Icewind Dale Trilogy, which was initially to be set in the Moonshae Isles.

As soon as the background was changed to Icewind Dale, Drizzt Do'Urden was invented as Wulfgar's sidekick, and succeeded him as the protagonist in following novels.

[3][4] As described in The Crystal Shard in almost medical terms,[5]: 66  Wulfgar is roughly 7 ft 0 in (2.13 m), blond-haired and blue-eyed (common for the barbarian tribes he hails from), and developed his awesomely muscled physique when he was in servitude to the dwarf Bruenor Battlehammer for five years—working alongside dwarves, who are renowned for being tireless.

[6] Tanja Monique Bruske-Guth sees Wulfgar's description in the novel as how the abstract attributes of a game character can be visualized and explained.

For instance, Wulfgar once pulled the prow of an entire ship out of the water, and once lifted a three-hundred-pound man with one arm, and then threw him through the tavern where the bar fight had begun.

He also used a large, irritable camel as a projectile weapon to defeat a gang of bandits in The Halfling's Gem, and escaped a flesh golem, Bok, that was slowly bear-hugging him to death by tearing off its head with his bare hands.

He participated in barbarian invasion of Ten-Towns, where Bruenor Battlehammer, a dwarf, knocked Wulfgar out by sweeping his legs out from under him.

Wulfgar took up the task of killing the white dragon Icingdeath (Ingeloakastimizilian) in order to gain credibility, take leadership of his tribe and restore their glory.

[9] In an effort to stop the harm he was doing, Wulfgar broke off from the Companions of the Hall, and wandered the North for a time, eventually finding himself at a tavern called the Cutlass, owned by Arumn Gardpeckk.

Wulfgar was then accused of the attempted murder of Captain Deudermont of the Sea Sprite, with whom he had sailed several years earlier.

After an incident in the small fiefdom of Auckney, involving the young king's wife and a lie concocted to save her illegitimate child, Wulfgar and Morik left with a young child, and Wulfgar was finally able to banish his demons without alcohol, after being shown an act of massive courage by the king's wife when she had nothing to gain from the act.

[10] With their help (and to a smaller degree Morik's, who had been sleeping with the female wizard of Sheila Kree's crew) he recovered his hammer, Aegis-fang,[10] after facing an entire clan of ogres.

Sometime afterward, Bruenor decided to look for another lost dwarven homeland called Gauntlgrym, and the dwarf's closest friends accompanied him, along with 500 dwarves.

On their trek through the Spine of the World, the caravan came upon the ruin of the small human settlement Clicking Heels, which had been sacked by a multitude of orcs and frost giants.

Bruenor then determined that he, Drizzt, Wulfgar, Catti-Brie, Regis, and a small detachment of dwarves, would see if other villages in the region had also been sacked.

It was during this time, that while out on patrol, one of Shallows' militia teams encountered a large force of orcs and was slaughtered, with only one survivor managing to escape and hide.

Repelling grapplers and sweeping aside those few who crested the wall, Wulfgar was unmovable, even after countless hours when exhaustion began to set in.

The orcs and pack animals then threw off their druid enchanted cloaks, revealing themselves as Regis, the Bouldershoulder brothers and a small force of Dwarves.

In the novel Gauntlgrym, it is revealed that Wulfgar lived a very long and healthy life, having several children and grandchildren before he finally died.

Aegis-fang (derived from the mythical shield Aegis[citation needed]) is the iconic weapon of Wulfgar, a mighty war hammer.

Its head is made from pure Mithril with a diamond coating magically adhered during the forging and an adamantite shaft.

Wulfgar appears in the Baldur's Gate II: Shadows of Amn computer role-playing game as minor NPC.

"[16] According to Aidan-Paul Canavan, Wulfgar is one of the characters that "exemplify the strong, honest, hot-headed young warrior hero type common to adventure stories and similar to Howard’s creation Conan".

He thus follows a typical trope in fantasy described by Susanne van Clewe: The hero, here Wulfgar, receives a magical item that grants him sovereign power.
