<P> Tyrion Lannister (season 1--present) portrayed by Peter Dinklage . Nicknamed "The Imp" or "Halfman", Tyrion Lannister of House Lannister is the younger brother of Cersei and Jaime Lannister . He is a dwarf; and his mother died during his birth, for which his father, Tywin Lannister, blames him . While not physically powerful, Tyrion has a cunning mind and often uses to his advantage the fact that others constantly underestimate him . In Season Three, Tyrion is given the job of Master of Coin, a role that he is unprepared and inexperienced for . Tyrion is commanded by his father to marry Sansa Stark; however, on the wedding night, Tyrion refuses to consummate his marriage and instead lets Sansa sleep alone, promising not to touch her unless she wanted him to . The death of her brother Robb, in which Tyrion took no part, causes a further rift between the couple and between Tyrion and his father, who he claims can't distinguish between his interests and his often - praised ideal of devotion to family . Tywin bitterly claims that he had wanted to drown Tyrion upon birth, but stayed himself for the sake of duty . In season 4, Tyrion welcomes Prince Oberyn Martell of Dorne to King's Landing for Joffrey's wedding to Margaery Tyrell, though Oberyn implies to Tyrion that his true purpose is to seek vengeance for his sister, who was murdered by Ser Gregor Clegane on Tywin's orders . When Joffrey is fatally poisoned, Tyrion is framed and arrested . Tyrion, however, implies that Cersei knows of his innocence and just wants him dead . At Tyrion's trial, he demands a trial by combat . Tyrion is approached by Oberyn, who volunteers to be his champion in order to fight Cersei's champion, Ser Gregor Clegane . When Oberyn loses the fight and is killed, Tyrion is sentenced to death . Jaime, however, frees Tyrion and arranges for him to escape King's Landing . Tyrion goes to confront Tywin in his chambers but finds Shae, who testified against him and is now Tywin's lover . After a brief struggle, Tyrion strangles Shae to death, and Tyrion shoots Tywin to death with Joffrey's crossbow . Tyrion is then placed in a crate and smuggled off to Essos with help from Varys . They arrive in Pentos, where Varys manages to convince Tyrion to travel with him to Meereen and aid Daenerys Targaryen in retaking the Iron Throne . Tyrion is bound and gagged by Jorah Mormont, who says that he will take him to Daenerys . Daenerys takes them both to her home in the Great Pyramid of Meereen and asks Tyrion why he is here . Tyrion tells her everything, including Varys' plan . He initially counsels her to stay in Meereen, but Daenerys makes it plain to him that her eyes are still on Westeros . Tyrion tells Daenerys how hard it will be to win the love of both the common people and the nobles . He later joins her at the opening celebrations of Daznak's Pit, where Jorah unexpectedly reappears to defeat every other foe on the arena . As the Sons of the Harpy attack, Tyrion manages to survive by fleeing to the midst of the arena, where they are rescued by Drogon, while Daenerys is spirited away on his back . In season 6, Tyrion struggles to maintain peace in Meereen, particularly when the Sons of the Harpy burn the entire Meereenese Navy, stranding them in Slaver's Bay . Following an alliance with Theon and Yara Greyjoy, Tyrion advises Daenerys to break up with Daario so that she may pursue a marriage alliance in Westeros . In gratitude for Tyrion's loyalty, Daenerys names him her official Hand, and he accompanies her back to Westeros . In season 7 Tyrion's advice to Daenerys often conflicts with her views, and he has mixed success in directing her actions . He sneaks into King's Landing and meets with Jamie to set up a meeting between Cersei and Daenerys, which eventually happens in the Dragonpit outside the city . At the meeting a captured wight is produced to convince Cersei that the worst threat is from beyond the Wall . When Cersei is not convinced, Tyrion risks execution to meet with his sister to try again to persuade her . He is unexpectedly allowed to leave Cersei's presence alive, and thinks he has secured an agreement from her to help with the fight against the Wight Walkers . </P> <P> Khal Drogo (season 1--2) portrayed by Jason Momoa . Khal Drogo is a warlord of the Dothraki people . He is to marry Daenerys Targaryen, as arranged by her brother Viserys . He is undefeated in battle . Viserys Targaryen conspired with Magister Illyrio to marry Daenerys to Drogo in order to get his support in an invasion of Westeros . Though Daenerys was initially unhappy with the arrangement, Drogo proves to be a sensitive husband and lover despite his fearsome behavior with his men . After a failed poisoning attempt on Daenerys' life, he promises to invade Westeros to reclaim the Seven Kingdoms for the Targaryens, but Viserys's impertinence ultimately causes Drogo to kill him . Drogo maintains his promise for the benefit of his wife, but is wounded by an enemy khal before he could begin the invasion . The wound festers and Drogo becomes so sick that he is unable to ride his horse, a sign of weakness to the Dothraki . Most of his khalasar abandons him, but Daenerys unknowingly sacrifices their unborn child for a spell to revive him . The spell works, but leaves him a brain - dead husk of his former self . Daenerys smothers him out of pity, and the flames of his funeral pyre ultimately hatch her dragon eggs . </P> <P> Tywin Lannister (season 1--5) portrayed by Charles Dance . Lord of Casterly Rock, Shield of Lannisport and Warden of the West, Tywin of House Lannister is a calculating, ruthless, and controlling man . He is also the former Hand of King Aerys II . He is the father of Cersei, Jaime, and Tyrion . After Eddard Stark's arrest, Joffrey names him Hand of the King once more, but after Jaime is taken captive by the Starks, Eddard is unexpectedly executed by Joffrey, and Renly and Stannis Baratheon challenge Joffrey's claim to the throne; Tywin elects to remain in the field commanding his forces until he wins his war, and in the meantime gives the position of Hand of the King to Tyrion . Tywin continues the war through Season 2 at Harrenhal where he criticizes his commanders for losing and underestimating the Stark army led by King Robb Stark . While there, he forms an unlikely friendship with his cup bearer, unaware that she is actually Arya Stark . Originally, he was about to attack Robb's forces while they are distracted by the Greyjoys seizing Winterfell, but changes his mind and helps the defenders of King's Landing drive Stannis Baratheon's forces away . He assumes his position of Hand of the King once again and arranges for Joffrey to marry Margaery Tyrell to secure an alliance between the Lannisters and Tyrells . In the third season, as Hand of the King, he fortifies his position as de facto leader of the Seven Kingdoms, and he successfully defeats Robb Stark, the King in the North, by forging an alliance with the lords Frey and Bolton, who betray and kill Stark and his men . The crown subsequently pardons and rewards them with Riverrun and the North, respectively, though Tywin is criticized by Tyrion for winning the war through such an unscrupulous scheme . He also has to deal with an increasingly belligerent Joffrey, who chides his grandfather as a coward who "hid under Casterly Rock" while Robert Baratheon led the rebellion against Aerys Targaryen, and complicated relations with his children as he forces them into marriage alliances with Sansa Stark and Loras Tyrell, to secure the support of the Tyrells and Lannister dominion in the North (now Sansa's heirdom, as all her brothers are presumed dead). In the fourth season, Tywin is present at the royal wedding where Joffrey dies, and has King's Landing closed off to prevent Sansa from escaping (although she escapes with help from Petyr Baelish and Dontos Hollard). He grooms Joffrey's younger brother, Tommen, to becoming the new King, and appears determined to make sure Tommen becomes a much better King than Joffrey was . The presence of Prince Oberyn Martell of Dorne poses a new problem, however, as he resurfaces the Martell--Lannister antagonism over the rape and murder of his sister Elia by Gregor "The Mountain" Clegane during the Robert's Rebellion; Oberyn believes the deed was done on Tywin's order . Tywin denies the allegations and promises Oberyn justice in exchange for Oberyn serving as one of the judges at Tyrion's trial . At the trial, when several supposed witnesses give false statements regarding Tyrion's supposed guilt, Tywin promises Jaime in private that if Tyrion is found guilty and pleads for mercy, he will exile him to the Night's Watch but only if Jaime ceases to be a Kingsguard and takes his place as heir to House Lannister . However, Tyrion loses his composure, lashes out at Tywin and demands a trial by combat, to Tywin's anger . When Tyrion's champion, Oberyn, loses the fight and is killed, Tywin sentences his son to death . Later, when Jamie helps Tyrion escape, Tyrion discovers that Tywin was having an affair with Shae, Tyrion's former lover, who falsely testified against him at his trial . Tywin is ambushed by Tyrion while in a privy, wielding Joffrey's crossbow . Tywin attempts to reason with Tyrion, swearing that he would never have had him executed, but also--upon Tyrion showing regret for Shae's death--taunts him as "afraid of a dead whore". In rage, Tyrion shoots Tywin twice in the chest, killing him . His body is discovered shortly afterwards, and a grand funeral is held in the Sept of Baelor . As revealed by Davos Seaworth, he was 67 years old . Tywin's death heralds instability in the Seven Kingdoms, with the arrival of the Sparrows in the capital, and rivalry rising between Cersei, who aspires to her father's position but lacks many of his statesmanlike qualities, and the Tyrells . The Boltons also lose the potential Lannister military support just when they are faced with Stannis Baratheon planning to take Winterfell on his way to the Iron Throne . </P> <P> Davos Seaworth (season 2--present) portrayed by Liam Cunningham . Ser Davos Seaworth, also known as "The Onion Knight", is a former smuggler and knight in the service of Stannis Baratheon; he serves as one of Stannis's most trusted advisers . In his smuggling days, he was said to handle a ship at night better than anyone . Before the events of the series, he earned his knighthood by smuggling fish and onions to the besieged Stannis Baratheon and his army during Robert Baratheon's rebellion . Before knighting him, Stannis removed the last joints from four fingers on his right hand as punishment for his years of smuggling; believing these joints bought his family a better future, Davos keeps them in a pouch around his neck for luck . In Season 2, he loyally supports Stannis' claim on the throne and his honesty and willingness to voice his unaltered opinion makes him Stannis' most trusted adviser, though Stannis often dislikes what he hears . An agnostic, he doesn't accept the priestess Melisandre and her god R'hllor but does not object to her because Stannis is also a follower of R'hllor . He fights in the Battle of the Blackwater, where his ships are caught in a giant explosion of wild fire . His son Matthos is killed and Davos is thrown out to sea . He is picked up by the pirate Salladhor Saan, who returns him to King Stannis . Upon attacking Melisandre for the loss of his son, he is imprisoned and later condemned to death for releasing Gendry . Stannis had intended to sacrifice the boy to R'hllor and hence regards Davos' actions as treason, but Davos shows him a letter from Maester Aemon from the Night's Watch, detailing the death of Lord Commander Jeor Mormont and Samwell Tarly witnessing the growing army of White Walkers . Stannis pardons Davos upon Melisandre's request, as she claims R'hllor calls them to travel to the Wall to help the Night's Watch protect the kingdom from the White Walkers . In season 4, Davos is still at odds with Stannis for releasing Gendry (as Stannis claims that Robb Stark and Joffrey Baratheon are dead thanks to Gendry's blood) and failing to find him a suitable army, but Davos decides to write a letter to the Iron Bank of Braavos so that they may provide them with the currency to purchase an army to aid the Night's Watch against the 100,000 strong wildling army led by Mance Rayder . Despite the Iron Bank's reluctance to back Stannis, Davos manages to convince them and they acquire the loan . Davos then tracks Salladhor Saan to aid them in exchange for gold . He and Stannis arrive at the Wall in time to save Jon Snow from Mance Rayder . In season 5, Davos remains at the Wall with Stannis to help him in his campaign to retake the North from Roose Bolton . Davos is aware that the Night's Watch will choose a new Lord Commander and believes that Ser Alliser Thorne will win . He tries to convince Jon Snow to accept Stannis's offer of legitimization since Thorne will most likely punish Jon for showing Mance Rayder mercy during the execution . Later, Davos departs from the Wall with Stannis, to help him take Winterfell . As the army becomes snowbound, he is returned to the Wall on Stannis' command, sharing a heartfelt moment with Shireen, where he thanks her for learning him to read and promises to be back within days . Arriving at the Wall, he unsuccessfully tries to convince Jon of their cause, when the couple is suddenly joined by a lone Melisandre, whose sullen demeanour is enough to tell Jon and Davos that Stannis and Shireen are dead . In season 6, after Jon is killed in a mutiny, Davos leads Jon's loyal friends against the mutineers led by Alliser Thorne and they achieve victory thanks to the wildlings' help . Davos later persuades Melisandre to attempt to resurrect Jon, which she succeeds in doing, and becomes one of Jon's top lieutenants in his campaign to retake Winterfell from the Boltons, successfully persuading Lyanna Mormont to supply them with men . He takes part in the Battle of the Bastards and survives, but in the process learns that Shireen was actually burned at the stake by Melisandre . He confronts her about it in front of Jon and she admits her role in Shireen's death, and he demands permission from Jon to execute Melisandre, though Jon has her exiled instead . Davos later joins the Northern Lords in proclaiming Jon the new King in the North . In season 7 Davos travels with Jon to Dragonstone . He helps Tyrion Lannister to sneak into King's Landing for a meeting with Jamie Lannister . While in King's Landing he seeks out Gendry and finds him in a smithy, and brings him back to Dragonstone . </P>
