Broxigar was a veteran orc warrior of the First, Second, and Third Wars, and older brother of Varok Saurfang.
When the Horde shamans detected the temporal anomaly in the Stonetalon Mountains, Broxigar was sent to investigate and eventually was thrown ten thousand years into the past along with the human mage Ronin and the dragon-mage Krasus, during the War of the Ancients.
Brox's fighting skills earned him a fair reputation among the Kaldorei Resistance against the Burning Legion. Malfurion, under the forest demigod Cenarius' direction, created a mystical axe of wood enchanted with a piece of Kalimdor's magic, making it light as a feather and stronger than any mortal-forged axe. In Brox's hands, it was to be the death of literally thousands of demons and allowed him to achieve the unthinkable against their lord.
At the final battle over the Well of Eternity, Brox realized that if the world and the future were to be saved, his companions needed more time. Brox leapt from the back of one of the red dragons also carrying Rhonin into the swirling portal that was opening at the bottom of the funnel. When he passed through, and arrived on Argus, homeworld of the Burning Legion, he proceeded to slaughter multitudes of demons. He eventually attracted the attention of Sargeras, who came personally to put an end to the orc's life. However, Brox did the impossible, and with the Axe of Cenarius struck a small wound in Sargeras' leg. This wound would later be the focus of Krasus and his allies' spellwork, that for a second, tore Sargeras' attention away from his struggle to keep the portal open... allowing Malfurion and Illidan to close it upon him. Brox's life was ended by Sargeras, right before the demon entered the portal, by the jagged edge of Sargeras's broken sword, and Krasus saw Brox's lifeless corpse impaled on its end. With this final act of loyalty, Broxigar the Red sealed his place in history as one of the only known mortals to have ever assaulted the Burning Legion's leader.
Broxigar the Red died, not a mere honorable death, but was graced with an unimaginable glory never being heard of in the history of the orcs. In the afterlife, he finally reunited with his deceased comrades in the past.
