Game Of Thrones will always be one of the most epic television shows to ever grace our screens.
From its debut a decade ago, audiences across the world continue to invest in and re-watch HBO's fantasy epic, which became a global juggernaut across its eight-season run and made household names of the majority of its gigantic ensemble cast.
But sadly, while a great number of those characters have reached an iconic status in the years since the show's debut, many others failed to leave a significant mark. It's not too surprising - George R. R. Martin's novels remain unfinished to this day, and even with a grand total of 73 cinematic episodes, not every character was going to be developed in the same manner when being adapted from page to screen.
As such, many of those who appeared after the show's debut season remained underdeveloped and became either a missed opportunity or a waste of acting talent.
In Game Of Thrones' first season, the story remained very close to the source novel, before more creative decisions were made from the second season onwards. Here's our picks of the characters who ended up being rather underwhelming as a result...
10. Trystane Martell
The worst part of this first entry is it actually took a re-watch of the show for this author to even remember what happened to this poor guy. If you can't remember yourself, check out Season Six - it's gruesome.
Trystane Martell is the only son of Prince Doran Martell and the heir to Dorne, the southernmost region of the Seven Kingdoms. Introduced in Season Five, Trystane is betrothed to Myrcella Lannister and is caught up in events which sees Jamie Lannister and Bronn attempt to collect Myrcella from the region. After the strong reception to Trystane's Uncle Oberyn in the previous season, we were expecting a big entrance from this young prince.
Sadly, the result is lacklustre.
Instead of the heroic maverick we were all expecting, Trystane is used for comedic humour only, taking a beating from Bronn and leaving audiences wondering how he actually made it so far into the show's run. It doesn't get much better from there, and the handful of scenes the character gets are no more than filler.
To top it all off, he's killed about five minutes into the next season, by his cousins no less, who assassinate him to stop him taking revenge on their killing of Myrcella. But more on that shortly...
