Daenerys has many titles, all hard-earned: Mother of Dragons, Breaker of Chains and Khaleesi of the Great Grass Sea. Most of all, she fights to claim the Iron Throne.
Brienne rebukes gender stereotypes with her armor, her sword -- and her ability to stand up to any male knight.
In Season 7, Samwell's life partner cracked open a book -- and unlocked the secret to Jon Snow's parentage. Reading is definitely power.
Though we last saw her in chains, thanks to her uncle Euron (Pilou Asbæk), Yara is a strong and capable heir to her father's seat as Lord of the Iron Isles.
Never underestimate the power of someone who can produce a Shadow Baby -- especially if that someone is also the priestess of the Lord of the Light.
She who rules from the Iron Throne is the toughest of all. Period. (Now as to whether Cersei will still have the throne by the end of Season 8...)
In Season 7, Alys calmly -- but bravely -- faced the possible wrath of Jon Snow (Kit Harington). Speculation is high that the Lady of Karhold will figure into Season 8.
In Season 7, Meera bade farewell to Bran Stark (Isaac Hempstead-Wright) after countless hours (and seasons) of dragging the Lord of Winterfell across frozen tundra. It sounds like the character's portrayer won't be too sad if she doesn't get the call for Season 8: "I was ... slightly relieved for my spine," Kendrick said in an interview.
Another Sand Snake fatality of Season 7, the bold Obara engages Euron Greyjoy (Pilou Asbæk) in combat, but comes away impaled.
Seen in happier, heavily armed days, the third Sand Snake is likewise offed in Season 7: the victim of the kiss of death, literally, courtesy of Cersei Lannister (Lena Headey).
The last we saw the leader of The Sand Snakes, Ellaria, she was watching Tyene die in a dungeon in an act of revenge for Ellaria having killed Cersei and Jaime's daughter, Myrcella Baratheon (played by Nell Tiger Free in Seasons 5 and 6).
