Rakharo is a loyal Dothraki bodyguard to Daenerys Targaryen. Following the birth of her dragons he is named a bloodrider by his Khaleesi. He is killed by a rival khalasar while scouting the Red Waste.
Rakharo is a Dothraki warrior who is skilled in combat. He is young, but extremely capable in battle. He was trained by his father, who was a bloodrider in the retinue of a famous khal, Khal Bharbo. He is descended from a long line of bloodriders. He protected Daenerys from her brother's vicious temper and was one of the first to declare her "blood of my blood."
Khal Drogo assigns Rakharo to be the bodyguard of Daenerys Targaryen, Drogo's khaleesi. Their marriage was brokered by her brother Viserys in exchange for Drogo's assistance in reclaiming the Iron Throne for House Targaryen. Drogo takes the khalasar east to Vaes Dothrak. Rakharo discreetly follows Daenerys when she briefly leaves the column to walk in some nearby trees and witnesses her brother Viserys unleashing his rage upon her. Rakharo disables Viserys by whipping him around the throat. At Daenerys's request he spares Viserys, but forces him to walk back to the khalasar by taking his horse. Later, he and Ser Jorah Mormont discuss the relative merits of Dothraki and Westerosi weapons and armor before he gets into a petty argument with Daenerys's handmaiden Irri over what to prepare for dinner. Irri reveals that Daenerys is pregnant and demands the slaughter of a goat.
Viserys continues to press Drogo to fulfil his promise immediately and drunkenly threatens Daenerys in front of the khalasar. Rakharo watches as Drogo kills Viserys using a crown of molten gold. Rakharo apprehends an assassin who attempts to poison Daenerys in the markets of Vaes Dothrak after he is exposed by Ser Jorah.
The assassination attempt causes Drogo to vow to take the Iron Throne for Daenerys. He takes the khalasar south to raid the Lhazareen people to obtain slaves in order to fund the invasion. Rakharo accompanies Daenerys during the Khalasar's raid on a Lhazareen village. Daenerys objects to the dothraki's treatment of the slaves. Rakharo stops the dothraki raping the women. Daenerys' actions provoke dissent and lead to a fight between Drogo and Mago. Drogo easily kills Mago but allows Mago to inflict a small wound while initiating the fight. Drogo's wound festers and he falls from his horse during the journey to sell the Lhazareen slaves. Rakharo stays loyal to Daenerys and carries out her commands even when the other Dothraki begin to blame her for Drogo's decline into illness. Qotho attacks Daenerys and Jorah intervenes, killing Qotho. Daenerys goes into premature labor. Daenerys son dies and Drogo is left in a vegetative state. The Lhazareen maegi Mirri Maz Duur takes responsibility. Daenerys ends Drogo's misery and then builds a funeral pyre for him. She orders Rakharo to place her dragon eggs on the pyre and then to bind Duur within the flames. Daenerys steps into the inferno as her people watch. They stand vigil through the night and in the morning they find her amongst the ashes with three newly hatched dragons. Rakharo joins Ser Jorah in declaring his loyalty to her.
Rakharo becomes one of Daenerys bloodriders along with Aggo and Kovarro. Daenerys leads what remains of her khalasar deep into the Red Waste to avoid attack from rival khalasars or retribution from the Lhazareen. Facing starvation she sends Rakharo, Aggo and Kovarro to scout in three different directions, using the last remaining horses. Rakharo is sent North East. Daenerys says goodbye to him personally and tells him that he has never failed her. He says that it is a bad time to start.
Rakharo's horse returns to the khalasar without him. Jorah Mormont approaches the horse to find Rakharo's decapitated head in a bag (along with his cut braid of hair, to mark his defeat), speculating he might have been killed by Khals Pono or Jhaqo to show their contempt for a female leading a Khalassar. Irri, who was in love with Rakharo, is distraught because, according to Dothraki belief, his spirit won't be able to move on to the Night Lands - the afterlife - to ride with his ancestors.
Daenerys' Dothraki bodyguard, Rakharo was dscended from a line of bloodriders. Among those who stayed with Daenerys after Drogo's death and the first to declare her "blood of my blood", Rakharo was killed by a rival khalasar during a scouting mission.
