Fictional Character attributes
Garrosh Hellscream was a former Warchief of the Horde chosen by Thrall to replace him in the wake of the Cataclysm, until he was succeeded by Vol'jin after the Siege of Orgrimmar. Throughout the history of Azeroth, few mortals have achieved greater notoriety than him.[9]
Garrosh grew up on Draenor in the shadow of his father, the great warrior Grommash Hellscream, leader of the Warsong clan. Grom was the first orc leader to drink the blood of Mannoroth, subjugating the orcs to the Legion's will. Before this event, Garrosh was among several orcs who had become ill with the red pox. They had been quarantined far away in Nagrand, allowing them to escape the demonic corruption. The younger Hellscream was ashamed of his father for many years until he met Thrall during the invasion of Outland and learned of Grom's heroic redemption. Garrosh has since embraced his potential as a strong leader, most notably in Northrend, where he directed the Horde advance through the Borean Tundra and won the hearts of his people. Uncompromising and fiercely proud, Garrosh intended to restore the orcs' glory by any means necessary.[10]
As the renewed Alliance-Horde war developed, Garrosh's thirst for power corrupted him to the point that he did not care about the means used to bring the orcish supremacy on Azeroth, with himself as the world's supreme ruler - going as far as to unleash the full power of the dead Old God's heart by resurrecting it using the Pools of Power, effectively destroying half of the sacred pandaren Vale of Eternal Blossoms.
Ultimately, he became the final antagonist of Mists of Pandaria's Alliance-Horde war arc. He was ultimately defeated and depowered and then captured by the coalition below Orgrimmar. He was to be tried in Pandaria as a war criminal, but managed to escape to an alternate Draenor through the efforts of Kairoz, and Garrosh's own loyalists aided by the infinite dragonflight. There, he was able to confront Gul'dan and witness his transformation into one of the first green orcs, corrupted by the influence of the fel powers, and slowly change the course of events leading to the birth of the Iron Horde.
In Warlords of Draenor, Garrosh set things in motion. Thanks to his connections with the Blackfuse Company who supplied him during the Siege of Orgrimmar, he supplied the orcish clans of Draenor with all the technology they required to build their war machines, and he influenced alternate Grommash to unite all orcish clans under one banner and reject the blood of Mannoroth. Garrosh also managed to give an idea to create a gateway between the alternate timeline and the main one in order to return to exact his vengeance on Azeroth, in a form of the Iron Horde's Dark Portal within Tanaan Jungle, using the leaders of the Shadow Council as the portal's power source and then sent the Iron Horde in order to conquer the world, as well as entrusted Warlord Zaela to arm the Iron star within Blackrock Mountain in order to annihilate Stormwind City. He could later be found as the warlord of the Warsong clan in Nagrand where he was eventually defeated and killed by Thrall in a mak'gora. Following his death, Garrosh's soul was confined to the realm of Revendreth and later the Maw for his sins. However, he remained unrepentant for his actions to the last and ultimately chose to destroy himself rather than submit.
Garrosh was one of the main characters in The Burning Crusade, Wrath of the Lich King, and Cataclysm. He later becomes more antagonistic, serving as the main antagonist of Mists of Pandaria and the supporting antagonist in Warlords of Draenor.
