Now that we know The Mountain will be returning to Game of Thrones Season 4, we should probably offer a refresher on who this character is, since he hasn’t been seen since Season 2, Episode 8, and there are kind of a lot of characters on this show.

Gregor Clegane, better known as “The Mountain That Rides”, or just “The Mountain,” is the brother of Sandor Clegane, AKA “The Hound.” Clearly the Clegane family is into weird nicknames, but what else do we know about The Mountain?

The Mountain made his first appearance on the show back in Season 1. At the time he was played by Conan Stevens, and appeared as a monstrous brute who was defeated by Ser Loras Tyrell in a jousting match during the Tourney of the Hand. After The Mountain was defeated, he decapitated his horse and attacked Ser Loras, who was rescued by The Hound, and The Mountain stormed off. We also learned during this scene that The Mountain is responsible for The Hound’s disfigurement, having pushed him into a fire when they were children.

The next we heard of The Mountain, he was wreaking havoc in the Riverlands. Upon hearing word of this, Ned Stark, who was acting as Protector of the Realm while King Robert was out hunting, sent a group of men (including Beric Dondarrion) to bring The Mountain to justice. Since The Mountain is also a croney of Tywin Lannister, this move by Ned acted as a precursor to the Lannister’s war with the Starks.

The Mountain appeared again in Season 2, this time portrayed by Ian Whyte, at Harrenhall, where he was in charge of the group who was torturing Gendry, Arya, and their friends (though Arya managed to avoid torture). He was looking for information regarding the Brotherhood Without Banners, whom we met in Season 3. If you recall in that season, Beric Dondarrion stated that The Mountain was responsible for one of his six deaths.

The Mountain has a reputation as the largest, strongest and most ruthless knight in Westeros. If Season 4 is anything like the books, he'll play a big and thrilling part in the new season. We hope the third actor to take on this role, Thor Bjornsson, is up to the task.
