[SPOILER] Makes a Surprise Return in 'Game of Thrones'

Beric Dondarrion

Role: Leader of the Brotherhood without Banners

Unless you're Jon Snow or Beric Dondarrion, death is usually permanent in Game of Thrones.

We briefly saw Dondarrion in season one when Ned Stark sent him and Thoros of Myr to stop Sandor "The Mountain" Clegane's assault on the Riverlands. That fight went poorly for Dondarrion, but Thoros's prayers to the Lord of Light somehow resurrected Beric after he was cut down by the Mountain in battle.

In season three, We saw Beric and Thoros's rebellious Brotherhood without Banners group after they encountered Arya and the Hound during their travels to the Red Wedding. Although Dondarrion died during a "trial by combat" against the Hound, Thoros resurrected him again.

The Brotherhood reappeared last season and successfully recruited the Hound to their side. They seem to be making their way North, where the forces of evil are gathering outside of the Wall.

Dondarrion has not only cheated death multiple times, he also wields a flaming sword that hearkens back to the fabled Azor Ahai who defeated the White Walkers' first assault against Westors. Is Dondarrion the "Prince Who Was Promised?" We'll likely find out this season.

Yara Greyjoy

Role: Leader of Daenerys's Fleet

The older sister of Theon Greyjoy, Yara arguably embodies the ideals and spirit of House Greyjoy far better than her brother.

In early seasons, Yara made several appearances of Game of Thrones, but she largely remained on the periphery of the War of the Five Kings and its aftermath. After reuniting with her brother last season, she and Theon fled the Iron Islands after their uncle Euron murdered their father and ascended to the Salt Throne.

The Greyjoys fled east and joined Daenerys's growing army. More importantly, Yara offered up her fleet to help Daenerys FINALLY cross the Narrow Sea and make her claim on the Iron Throne.

Once Daenerys steps foot on Westeros, it seems like she might not have much use for Yara and her ships. But Yara still has a confrontation ahead with her uncle, one that might get violent before too long.

Lyanna Mormont

Role: Ruler of House Mormont

Easily, last season's breakout character was Lyanna Mormont. Although only a 12-year-old girl, Mormont was the only Northern Lord to put her support behind Jon Snow and Sansa Stark in their quest to free the North from Ramsey Bolton's tyranny.

Lyanna shamed the other Northern Lords for sitting on the sidelines and was the first to proclaim Jon Snow as the "King of the North," when Snow's army unexpectedly won the "Battle of the Bastards."

Now that Jon and Sansa's battle against the Boltons is over, they'll need to turn their attention to the White Walkers' army on the other side of the Wall. They'll need some strong allies to back their fight against the growing darkness and there doesn't look to be a wiser woman in the North than the Lady of Bear Island.

Gendry

Role: Bastard son of King Richard Baratheon

Last season, The line of Robert Baratheon officially ended with the death of Tommen Baratheon...even though we all knew he wasn't Robert's real son. However, Robert does have lots of children still alive thanks to his constant infidelities and trysts.

The only bastard child of King Robert ever named in Game of Thrones is Gendry, a young blacksmith's apprentice from King's Landing. After Robert's death, Gendry's master sent him away to avoid any retribution from the vengeful Queen Cersei.

Gendry made his way north with Arya Stark, before the Brotherhood without Banners found him and then sold him to Melissandre. Melissandre used Gendry's "king's blood" in a ritual, but Davos freed him before anything worse could happen to him.

The last we saw Gendry was way back in Season 3 when he was rowing away from Dragonstone. However, he's now the last of the Baratheons and we could still see him play some part in the coming wars ahead.

Meera Reed

Role: Bran Stark's companion

Way back in season two, Bran Stark first encountered Meera Reed and her brother during their flight from Winterfell after Theon Greyjoy betrayed the Starks. Meera became Bran's primary protector and followed the young Stark beyond the Wall to find the three-eyed raven, even after her brother died at the hands of wights in Season 4.

Meera and Bran were the only survivors of the White Walkers' attack on the three-eyed raven's hideouts and literally dragged Bran away as Hodor made his tragic sacrifice and last stand.

Bran is the new "three-eyed raven" and as such will have to confront the Night's King at some point. And since the Night's King is also responsible for the death of her brother, Meera probably has a score to settle with the White Walker king as well.
