Just going off appearances, Wright has obviously changed the most.
Isaac Hempstead Wright as Bran Stark (Season 8)
But his character has as well, as he’s no longer (just) Bran, but the Three-Eyed Raven — and he took on a major role in the finale.
Lena Headey as Cersei Lannister (Season 1)
She didn’t start out as the best person, and sadly, that never changed.

Cersei also ended her time on the series as the enemy.
Nikolaj Coster-Waldau as Jaime Lannister (Season 1)
Jaime was a horrible person back then. Just ask Bran.

Jaime may have returned to Cersei in their final moments in Episode 5, but he did step up to help fight the dead.
Peter Dinklage as Tyrion Lannister (Season 1)
Once a Lannister, always a Lannister?

His family remained his weakness, even as he became the Hand to Daenerys.
Emilia Clarke as Daenerys Targaryen (Season 1)
She has come a long way, but her name may be her downfall.
Emilia Clarke as Daenerys Targaryen (Season 8)
She may have done some good over the past eight seasons, but as Episode 5 showed, choosing violence is not good for Targaryens.
Alfie Allen as Theon Greyjoy (Season 1)
Theon may have betrayed the Starks, but that wasn’t the end of his story.

In the end, Theon decided to fight — and give his life — for the Starks.
Game of Thrones has ended after eight seasons, and over the years, the actors and their characters have changed quite a bit.
Enemies have become allies. At least one character has gone mad. They've fought an Army of the Dead. A character's true identity has been revealed. Another has become something more than who he was. And, through it all, they've all been fighting for the Iron Throne.
Plus, how he feels about being one of the show's most hated characters.
Now, the series is over, and while not everyone has survived, we're looking back at the key cast members since the fist season. And in the finale, there was one surprise return — and everyone has noticed how much he has changed.
