As we all know by now, Game of Thrones is based upon the novel series A Song of Ice and Fire, and as a result the show draws most of its characters and plot from those books. In Season 4, we’re going to meet several new characters from the books, both major and minor, and we've been pondering who should — and might — get a bigger role in the show than they had in the pages of the novels.

Oberyn Martell. Oh Red Viper, we hardly knew ye. Oberyn only appears in a few chapters of A Storm of Swords before his unceremonious exit, but he still goes down as a fan favorite among many book readers because he’s just that awesome. He’s a swaggering, worldly, hyper-sexual badass who should play great on TV, so let’s hope the show introduces him early and waits as long as they can before getting rid of him.

Styr, Magnar of Thenn. Styr is a pretty cool character in the books, but, like Oberyn, he doesn’t last long. Styr is a very vicious wildling with an eerie appearance, and is an antagonist of Jon Snow’s in the book. While he and Jon should have already met by now according to the book’s timeline, the show is saving Styr for next season. Why’s that? We can only hope it’s because he gets to do something awesome, and gives Jon Snow a reason to hate him. The show can always use more unambiguous villains, and Styr has the potential for pure evil.

Ellaria Sand. The paramour of the Red Viper doesn’t have much to do at all in the books; she basically accompanies her man to King’s Landing and hangs out in the background, so hopefully the show can find more for her to do. She’s lowborn, foreign, and exotic, and therefore should be the perfect antithesis to Cersei. We’d really love to see her get under the Queen Regent’s skin and enjoy it, since there’s nothing better than watching Cersei squirm.

Mace Tyrell. While Mace isn’t what most would consider a “cool” character, he is despised by Cersei Lannister, so that’s enough for us to wish for more of him. While most of Mace’s actions and power-grabs are behind the scenes in the books, we’d love to see him wheeling and dealing with Margaery on-screen next season as part of his efforts to put the Tyrells into a position of power. And if he ends up being a bumbling idiot while Margaery proves to be the brains in the family, well, we’re OK with that, too.
