Arya Stark has become one of the most ruthless killers in Westeros. For the last six seasons, she's been driven by revenge, even keeping a list of people she means to make suffer for what they've done to House Stark. In Season 7, with the powers of the Faceless Men in her repertoire, she's become a seriously formidable assassin. Here's everybody who's died by Arya's hand (or her will) ... so far.
Stable Boy (Season 1)
Arya's first kill was almost accidental. She used Needle to stab an unnamed Stable Boy as she was fleeing the Red Keep, just as Lannister soldiers were rounding up and executing all House Stark's people in King's Landing.
Kill count: 1
The Tickler (Season 2)
After she saves Jaqen H'ghar's life (along with two others, who will come up later), the Faceless Man offers Arya a repayment: Name three people, and Jaqen will kill them. The first name she gives him is the Tickler, the torturer at Lannister-occupied Harrenhal. Jaqen breaks his neck.
Kill count: 2
Ser Amory Lorch (Season 2)
The second name Arya gives Jaqen is Amory Lorch, a Lannister knight. Lorch catches Arya with a message she stole from Lord Tywin. Arya has him killed before he has a chance to tell Tywin that she's a traitor, and Jaqen gets him with a poison dart.
Kill count: 3
A Frey soldier after the Red Wedding (Season 3)
Not long after escaping the Twins and the massacre of the Red Wedding, Arya and the Hound happen across four Frey soldiers. Arya approaches them asking for food, then brutally stabs one who was telling the others how they mounted the head of Robb Stark's direwolf, Grey Wind, on the King in the North's headless body. Arya tells the Hound the soldier is specifically the first man she's killed.
Kill count: 4
A Lannister soldier at the Inn of the Crossroads (Season 4)
Traveling with the Hound, Arya happens across a handful of Lannister soldiers in an inn. Arya recognizes them as some of the soldiers who intercepted her and her friends leaving King's Landing. They recognize the Hound and start a fight, and Arya kills one the Hound has injured.
Kill count: 5
Polliver (Season 4)
In the same fight at the Inn at the Crossroads, Arya takes the chance to reclaim her sword, Needle, from the man who stole it. She stabs the injured Polliver in the throat with Needle, the same way he killed her friend Lommy when Polliver captured her, Gendry and Hot Pie near King's Landing.
Kill count: 6
Rorge (Season 4)
Back when Arya met Jaqen H'ghar in Season 2, she was traveling with Yoren, a man of the Night's Watch. Yoren had Jaqen and two others locked in a cage atop a cart. Arya freed Jaqen and the others, one of whom, Rorge, had threatened to sexually assault her. When Arya and the Hound were attacked by Rorge later, she stabbed him in the gut with Needle.
Kill count: 7
Ser Meryn Trant (Season 5)
Ser Meryn is the guy who killed Arya's sword instructor, Syrio Forel, back in King's Landing in Season 1. When he arrives in Braavos, she gets her revenge by borrowing a face from the House of Black and White and pretending to be a brothel girl. She brutally stabs out his eyes and then slits his throat -- but as punishment, Jaqen H'ghar strikes her blind.
Kill count: 8
The Waif (Season 6)
Arya refuses to murder the actress Lady Crane for the Faceless Men, so Jaqen sends the nameless girl known as the Waif to kill Arya. The Waif nearly succeeds, chasing Arya all through Braavos, before Arya leads her into a dark room and dispatches her off-screen with Needle.
Kill count: 9
Lothar Frey and "Black" Walder Rivers (Season 6)
Arya leaves Braavos after defeating the Waif, intent to be Arya Stark rather than no one. She heads to the Twins, where she gets her revenge on the Freys. Off-screen, she kills Lord Walder Frey's two sons, Lothar and "Black" Walder, and bakes them into a pie she feeds to their father.
Kill count: 11
Lord Walder Frey (Season 6)
Lord Walder doesn't realize what's happening until Arya reveals she was using her Faceless Man powers to disguise herself as a serving girl. She slits Lord Walder's throat, getting revenge for his betrayal and murder of her brother, Robb Stark, and her mother, Catelyn Stark.
Kill count: 12
Every male member of House Frey (Season 7)
After taking out Lothar Frey and "Black" Walder Rivers, then finishing off Lord Walder Frey himself, Arya used her face-changing powers to set a trap that annihilated House Frey. She drew all the remaining Frey men together and, posing as Lord Walder, poisoned them all.
Kill count: 63
