Sua reputação é estabelecida muito antes de os livros ou shows acontecerem. Uma vez que ele perde a mão, no entanto, nunca o vemos em qualquer lugar perto de tão perigoso quanto ele estava com ele.
Mas suas realizações antes de perder a mão definitivamente justificam sua reputação.
Ele ganhou seu primeiro torneio aos idade de 13 anos :
At the age of eleven, Jaime was sent to Crakehall to squire for old Lord Sumner Crakehall alongside Merrett Frey. Two years later, while still a squire, he won his first tourney melee.
Ele estava lutando contra cavaleiros adultos, o que é bastante impressionante.
Possivelmente a maior conquista de Jaime foi a sua ascensão ao título de cavaleiro aos 15 anos de idade . Ele foi condecorado por Sor Arthur Dayne, depois que ele se manteve contra o Cavaleiro Sorridente da Fraternidade Kingswood .
Ele também foi o mais jovem a se tornar um Kingsguard . Embora seja possível que o Aerys II tenha escolhido Jaime apenas para mantê-lo próximo como uma forma de seguro para manter Tywin sob controle.
E obrigado a Mighty Mouse pelo comentário:
Also in the Battle of the Whispering Wood he made an impression on the north men, killing many soldiers on his way to challenge Rob in single combat. This would add to his reputation
As opiniões de alguns dos personagens principais sobre as proezas de Jaime na batalha:
Sansa Stark (A Guerra dos Tronos):
In the end it came down to four; the Hound and his monstrous brother Gregor, Jaime Lannister the Kingslayer, and Ser Loras Tyrell, the youth they called the Knight of Flowers.
Catelyn Stark (A Guerra dos Tronos):
“No one can fault Lannister on his courage,” Glover said. “When he saw that he was lost, he rallied his retainers and fought his way up to the valley, hoping to reach Lord Robb and cut him down. And almost did.”
“He mislaid his sword in Eddard Karstark’s neck, after he took Torrhen’s hand off and split Daryn Hornwood’s skull open,” Robb said. “All the time he was shouting for me. If they hadn’t tried to stop him--”
Brienne (Um banquete para os corvos):
Brienne remembered her fight with Jaime Lannister in the woods. It had been all that she could do to keep his blade at bay. He was weak from his imprisonment, and chained at the wrists. No knight in the Seven Kingdoms could have stood against him at his full strength, with no chains to hamper him. Jaime had done many wicked things, but the man could fight! His maiming had been monstrously cruel. It was one thing to slay a lion, another to hack his paw off and leave him broken and bewildered.
Kingbreaker (Uma dança com dragões) (possível spoiler):
Black as maester’s ink he was, but fast and strong, the best natural swordsman Selmy had seen since Jaime Lannister.
