“Live by these words: lok’tar ogar. Victory… or death.”
Garrosh Hellscream, son of Grom Hellscream and former chieftain of theWarsong clan, is the former Warchief of the Horde. With the reopening of the Dark Portal, Garrosh was invited into the Horde by Thrall himself, quickly advancing to the position of personal adviser of the Warchief. Garrosh led the Horde troops into Northrend and was given the position of acting Warchief in Thrall‘s absence.
Garrosh is well known for his fierce hatred of the Alliance and frequently expresses his desire for the Horde to go to war with its rival faction.
He later resurrected the Heart of Y’Shaarj and was replaced by Vol’jin as the Warchief of the horde.
He corrupted the Vale of Eternal Blossoms using the Heart of Y’Shaarj. The act turn the vale into the Vale of Eternal Sorrows and unleashed theSha of Pride. Taran Zhu is currently holding him for trial on Pandaria. 
Garrosh escapes trial and gets help from a friend calledKairozdormu, and goes back into the time of the Rise of the Horde and stops the Orcs from drinking the Blood of Mannoroth, He helps influence his father Grommash Hellscream unite the clans under the banner of theIron Horde to get his vengeance.
During the human invasion of Draenor, many Mag’har – the uncorrupted orcs whosettled in Garadar, a stronghold in Nagrand – were ill due to thered pox. Garrosh was among them.
Kargath Bladefist visited them at Garadar in search of warriors to aid him. Garrosh asked him about his father, and wanted to fight with him, but Kargath ignored him at first, calling the Mag’har weaklings and not orcs any more, and they could do the Horde a favor by dying.
Later on Garrosh asked Greatmother Geyah about his father, but the answer caused him to enter a deep depression.
Garrosh became an important chief among the Mag’har. He was aided byJorin Deadeye, son of the Bleeding Hollow clan’s former chieftain, Kilrogg Deadeye. When our heroes first meet Garrosh, he is sullen, pessimistic, even depressed. Undoubtedly he is worried about the health of his clan’s matriarch, Greatmother Geyah, who is ill. Garrosh knows that when she dies, he may be expected to lead the Mag’har, and that troubles him as well. Garrosh believes himself fated to repeat his father’s mistakes.
A great and fearsome warrior, Grommash Hellscream lusted for power. Despite his awareness of this weakness, Grommash nevertheless drankMannoroth‘s blood, which made him stronger and fiercer, but also damned Grom and other orcs to servitude under Mannoroth.
Early on, it is clear Garrosh is ashamed of his father. The last news Garrosh had of his father was that he (Grom) had drank the blood. Everything that transpired after this event is initially unknown to Garrosh. Indeed, Garrosh does not learn of his father’s heroic death until Thrallarrives in Nagrand and re-enacts events for Garrosh’s benefit. Learning that his father had eventually overcome his weakness for power – Grom gave his life so that the orcs would be free of demonic influence – Garrosh appears to gain strength and confidence, believing he is no longer fated to fail himself and his people.
Thrall brought with him Garrosh Hellscream back to Azeroth to be his adviser. Later on the retired gladiator master Rehgar Earthfury also became one of Thrall’sadvisers. Rehgar and Garrosh had a great discussion: while Garrosh wanted to destroy the Alliance, who he considers the Horde’s enemies, and take Azeroth for their own; Reghar wanted to remain open to diplomacy with the Alliance and conserve their treaty of non-aggression with Theramore.
When Thrall decided to go to a new meeting with the human King Varian, he brought with him his two advisers Rehgar and Garrosh and some Kor’kron. Reghar recommended Thrall not to bring Garrosh with them but the Warchief thought it would be a good idea as it would help Garrosh to re-think his attitude toward the humans.
Garrosh alongside Thrall traveled in a zeppelin to Theramore, where Varian and Thrall had a peaceful discussion with an eye toward mutual gain; though Garrosh thought it better for the Horde to take what they needed by force rather than exchange their resources. They first talked of their pasts and then discussed resource problems, like the Horde’s war against the night elves for lumber. Varian offered to provide Thrall’s people with the lumber and in exchange the Warchief offered copper and exotic hides in return. Varian had to leave early as Goldshire andSouthshore were said to be under simultaneous distress by the Scourge. Upon exiting Theramore, theTwilight’s Hammer clan invaded the city. After catching a glimpse of Garona, Varian thought that Thrall had sent her to assassinate him as the Shadow Council had done to his father. After a time battling, the Twilight’s Hammer’s casualties began to rise. Med’an then entered to protect his mother, and in seeing this, the cultists appointed their attention to the kidnapping of Med’an, while leaving Garona to die. Garrosh accused the Alliance of plotting the attack in an attempt to lure him and Thrall into a trap while Varian blamed the Horde; specifically Garrosh. Though tempers flared between Varian and Garrosh, Thrall and Garrosh left Theramore peacefully. Garrosh however felt that Varian had insulted the orcs’ honor and that by leaving peacefully the orcs were losing face at the summit.
Wrath of the Lich King Edit
Garrosh travels to Orgrimmar to meet with Thrall, Lady Sylvanas Windrunner,High Overlord Saurfang, Grand Apothecary Putress and Rehgar Earthfury to discuss what to do about the Scourge. After consulting Saurfang and the spirits, Thrall favored a more cautious approach to dealing with the Scourge: an advance scouting party to the frozen continent before committing troops, as well as meeting with Jaina Proudmoore to find out what the Alliance were planning to do about the Lich King.[1] Garrosh however, felt that dealing with the Alliance would put the Horde in danger and wanted to take the Horde’s armies and conquer the humans and then march to Northrend and crush the Scourge; advocating that the Horde should rule all of Azeroth.[2]Thrall, irritated by Garrosh’s recklessness and bold challenges to his authority, answered that the humans were not a threat[2] and that he would not underestimate the Lich King by walking blindly into a Scourge trap.[1] Thrall then provoked Garrosh to challenge him to a duel by saying that he would not make the same mistakes as his father, Grom Hellscream. Frustrated with his leader’s apparent lack of action and the insults to his father, Garrosh challenged Thrall to a duel in the Ring of Valor to settle the matter.[1][2]
The two orcs fought for some time until it seemed Garrosh had gained the upper hand.[1] He began to taunt Thrall, but the battle was interrupted by aHerald of the Lich King threatening Orgrimmar with destruction.[1] Hearing this, Thrall used Chain Lightning on Garrosh[2] and both left the ring, with Thrall telling the younger Hellscream that they would settle their dispute later.[1][2]The city was attacked by countless abominations and frost wyrms[1] and a fewdeath knights.[2]
Thrall and Garrosh led the forces of the Horde in repelling the Scourge attack, with the help of Saurfang, Sylvanas,[1] Reghar,[2] the city defenders, and someadventurers. After the Scourge assault force had been dealt with, Garrosh asked to be sent to Northrend again. This time, Thrall agreed and ordered Saurfang to begin preparations for war.[1]
Garrosh Hellscream was named Overlord of the Warsong Offensive, the main army of the Horde Expedition toNorthrend. He resides at Warsong Hold in the Borean Tundra, on Northrend’s western coast.
Unlike his appearance in Nagrand, where he was downtrodden and apathetic, Garrosh is much more hotblooded and reckless in his role as Horde commander in Northrend. His chief adviser, High Overlord Saurfang – who drank from the same chalice that corrupted Grom Hellscream – warns against Garrosh’s savage tactics, fearing a resurgence of the bloodlust that had dominated the Horde prior to the death of Mannoroth. The two often spar over tactical decisions, particularly in regards to supply lines between the Hold and the Forsaken forces in Howling Fjord. Even if he disagrees with Saurfang, Garrosh appears to have at least a grudging respect for the old warrior. When Saurfang warns Garrosh that if he goes too far against the Allianceand lead their people down a “dark path”, Saurfang threatens to kill Garrosh himself. Garrosh neither questions nor challenges Varok of whether he would actually carry out his threat but sarcastically questions how he managed to survive so long without falling victim to his guilt and sense of morality.
Despite Saurfang’s warning, Garrosh seems to have appointed commanders and be conducting the war in such a manner as to focus strongly on battling the Alliance. In particular, Conqueror Krenna, the commander atConquest Hold in the Grizzly Hills, bucks completely the war with the Scourge in favor of making war with the Alliance. Like Garrosh, she is hotblooded to the point of recklessness in pursuing the Alliance, so much so that she must be deposed by Gorgonna, an underling at Conquest Hold. The commander of Orgrim’s Hammerabove Icecrown is also concerned with defeating the Alliance in Icecrown, and even within Icecrown Citadel, the Horde faces off against the Alliance, as the Skybreaker and Orgrim’s Hammer do battle as well.
Thrall and Garrosh were summoned urgently to Dalaran to speak with the leader Rhonin. Arriving before the human King Varian Wrynn has departed, Garrosh and the king proceed to skirmish in the Violet Citadel, but Rhonin halts the fight with a magical shield before harm comes to either. Rhonin suggests that the Horde andAlliance work together against the new threat of Yogg-Saron in Ulduar, but Garrosh and Varian are partisan to the idea and Wrynn is portalled out. Garrosh expresses the opinion that a true Warchief would never partner himself with cowards
Garrosh, alongside Thrall, is in attendance at the new Crusaders’ Coliseum in Icecrown, surrounded by various champions and representatives of the Horde. Garrosh requests that Tirion uses warriors of the Horde to challenge the heroes in the tournament and to show the strength of the Horde.
As of patch 3.3.2, Garrosh can be found at Light’s Hammer inside Icecrown Citadel. He provides the Hellscream’s Warsong buff for Horde raiding parties. If you speak to him and tell him he is not needed, you will need to reset the instance (provided you are not already saved to it) in order to gain the buff again.
After Thrall steps down to join the Earthen Ring in stabilizing a world shattered by the Cataclysm, Garrosh is named to succeed him as Warchief of the Horde. Now in charge, Garrosh evicts the majority of non-orc and non-tauren NPCs from central Orgrimmar, believing only they possess the strength to truly defend the city. However, every race is still accounted for and while being a tough leader, Garrosh sees value in all the races that belong to the Horde and uses them to the best of that value.[4] He also begins remodeling the city with dark metal, similar to the Hellfire Citadel in Outland, along with Warsong Holdand other Horde bases in Northrend.[5] At Blizzard’s Comic-Con 2010 panel, it was revealed that a story was in production that would delve into the complicated relationship between Thrall and Garrosh, explaining exactly where Thrall’s faith in him comes from; the story will be available to read for free on the official website.[6]
Garrosh’s ascension to the Warchief’s throne has been applauded by the orcs, but is less than popular with the other races of the Horde, including the two closest allies of the orcs. Vol’jin, chieftain of the Darkspear tribe, absolutely despises Garrosh, condemning him as a warmonger and believes that his status as the son of Hellscream and as a hero of the war against the Lich King was the only reason that Thrall chose Garrosh to succeed him.Cairne Bloodhoof, High Chieftan of the Tauren, under the impression that Garrosh has deliberately undermined an attempt to peacefully obtain resources from Ashenvale, challenges Garrosh to a duel in Orgrimmar. Cairne is defeated, and it is later revealed that Magatha Grimtotem deliberately poisoned Garrosh’s blade, and that the poison incapacitated Cairne allowing Garrosh to slay him. Garrosh condemns Magatha to whatever fate the Earthmother deems fair and refuses to aid her in defending Thunder Bluff from Baine.[7] Sylvanas Windrunner, Dark Lady of the Forsaken, also seems to have a low opinion of the new Warchief, referring to him as an “ogre-headed buffoon”.[8]
Garrosh, in his updated character model, now wields Gorehowl, the axe of his father, Grom Hellscream.
Thrall sends new goblin players to meet with Garrosh after they leave the Lost Isles.
In the Stonetalon Mountains after Garrosh “dismisses” Overlord Krom’gar he learns the art of mercy from High Chieftain Cliffwalker.
Growing up, Garrosh only knew his father, Grom Hellscream, by the stories that cast him as the one who had doomed his people. But after learning of Grom’s redemption and heroic sacrifice to free the orcs from demonic corruption once and for all, Garrosh embraced his father’s legacy as a fearless warrior and natural leader. At times, Garrosh’s renewed zeal has put him at odds with the Horde’s warchief. Frustrated by Thrall’s decision to scout Northrend instead of mobilizing the Horde right away, Garrosh challenged the warchief to a duel in the Ring of Valor, but an assault by the Lich King’s minions cut their bout short. Garrosh and the warchief still have some unfinished business… and Garrosh’s hot-headed recklessness is fast becoming a concern to those who know the inherent danger in a Hellscream’s fury
It was revealed in the March 2012 Mists of Pandaria Press Event that Garrosh will be the final boss for the 
Mists of Pandaria expansion, as both factions recognize his growing instability and lust for power. The rebellion will be lead by Vol’Jin, who is seeking aid from both the Horde and the Alliance to fight against Garrosh. As the results would be terrible for either side should Garrosh prevail. [10] This means a new Warchief will be appointed and most assume Thrall will return, but 
Zarhym has hinted that the new Warchief may not be who everyone expects. Some believe the Warchief may not be an Orc. [11]
In Patch 5.4.0 Garrosh has been empowered by the power of Y’shaarj, the Dark Heart of Pandaria. 3 New models have been added, a new, more detailed Garrosh Hellscream model, a model where he is using the power of Y’shaarj, and the third is a limbo stage (left) where he is not quite either. In the patch 5.4 Trailer, he wounded the leader of the Shado-pan, Taran Zhu.
Garrosh is defeated by the combined forces of the Horde and the Alliance, and has now been put under arrest. He is to stand trial in Pandaria for his crimes. The title of Warchief was then placed upon Vol’Jin.
In Warlords of Draenor, Garrosh escapes the pandaren trial and goes back in time, before the orcs first invaded Azeroth, to stop the orcs from drinking the blood of Mannoroth. His goal is to unite the orc clans under the banner of the Iron Horde. Using technology from his own time, he intends to march through an altered Dark Portal to attack this time’s Horde and Alliance.
