Robb Stark
Richard Madden's striking resemblance to the AI's imagined depiction of the eldest Stark child, Robb Stark, is uncanny. Nevertheless, a few small inaccuracies should be noted. Firstly, like the rest of the Stark children, Robb was aged up in the show, transitioning from 14 to 17.
Secondly, in the books, Robb was meant to take after his Tully lineage, which should have given him reddish hair and blue eyes. Additionally, in the books, he is described as being particularly close to his half-brother, Jon. Regrettably, his fate in both the show and the books remains unchanged.
