Readers of A Song of Ice and Fire, the series of novels Game of Thrones is based on, know that the show is quite faithful to the source material, but it still makes quite a few changes. Recently, series George R. R. Martin said that he believes Littlefinger is the character who’s been the most altered from page to screen, which got us thinking about which other characters have undergone big changes.

So here are our candidates for which characters have changed the most. Read through our reasons, and then let us know what you think!

Gendry. Gendry’s storyline has veered wildly off-course from the books, and the reason for that is that his plot has melded two different characters together. In the books, there is Gendry, the bastard son of Robert Baratheon, who befriends Arya and joins the Brotherhood without Banners. OK, we’ve seen that on the show. But the books also feature another bastard son of King Robert, Edric Storm, who is taken by Melisandre to be sacrificed to the Lord of Light before being set free by Davos. Sound familiar? That’s because Gendry also filled Edric’s role on GoT. Edric hasn’t been seen in the books since Davos sent him away, so we can honestly say we have no idea what lies in store for Gendry in Season 4 of GoT.

Margaery. In the books, Margaery  seems like a sweet, innocent sixteen year old girl with little ambition of her own, and it's hard to tell how much agency (if any), she has in her family's plotting. It seems like she's largely being used by the Tyrell family, including her father Mace and grandmother Olenna, to be put their family in a position of power. The show, on the other hand, makes it very clear that Margaery is ambitious in her own right, and she's very manipulative and conniving in her efforts to become Queen of the Seven Kingdoms at any cost.

Joffrey. In the books, Joffrey is still a major jerk, but his appearance is radically different. He is depicted as a tall, athletic, and handsome prince who shares more in appearance with Nikolaj Coster-Waldau (Jaime Lannister) than Jack Gleeson (Joffrey). We have to say though, we love what the show has done with the character. Jack has taken Joffrey and turned him into one of the most-unique and hated villains of all time, and we wouldn’t have it any other way. #RoastJoffrey.
