When Marvel decided to create a superhero based on the mythological being, Thor, his iconic weapon of choice, Mjolnir, was adapted into the comics as well. In recent years, it has become an integral part of pop culture thanks to the ever-growing popularity of the MCU. A significant change that Marvel comics made was to give the hammer a "worthiness" attribute, which essentially makes it capable of being wielded by only a few people. There is no hard and fast rule as to what makes someone worthy or unworthy, which just makes discussions about what fictional characters would be able to wield this fictional item even more fun.
The fantasy-fueled world of Game of Thrones is not so different from Thor's own mythologies, and it is populated by characters, each more complex than the other. None of them might be actual Gods of Thunder, but it could be argued that some just might good-hearted enough be worthy of this superb weapon.
Worthy: Jorah Mormont
From a slightly skewed point of view, GoT can be seen as the story of a man in love with the Queen he serves and his eternal battle to get out of the friendzone, a battle that ends in failure. The man in this case being none other than Ser Jorah Mormont.
He starts as a double agent, working against Daenerys but soon comes to respect and love her so much that he gives up his chance to return to his homeland of Westeros for her sake. Loyalty is the name of the game when it comes to Jorah and House Targaryen would certainly appreciate his sacrifice in the end.
Not Worthy: Cersei Lannister
No one looks cooler drinking red wine while hatching evil schemes than Cersei, but all things considered, she was a pretty horrible person. In her own words, there was no middle ground when one was playing the game of thrones, and she was certainly playing to win.
Problematic physical relationships aside, it was her actions as an arrogant and prideful queen that inevitably lead to the destruction of King's Landing and the death of its populace.
Worthy: Theon Greyjoy
Theon Greyjoy's character arc is something of a rollercoaster. The brotherly bond that he shared with Robb and the others was admirable, but his act of betraying the Starks destroyed any credibility he ever held as a character and instantly made him hate-worthy in the eyes of the audience.
However, he eventually manages to right his wrongs and prove the Stark loyalty was still somewhere deep within him - even sacrificing himself to protect Bran. His fall from grace and struggles to reclaim his integrity could be compared to Thor's own journey of trying to achieve worthiness.
Not Worthy: Joffrey Baratheon
Anybody who has seen GoT will need no explanation as to why Joffrey Baratheon can't possibly be worthy, or why the only thing he is worthy of is the gallows. It's almost as if someone googled the worst characteristics that a human being could have and put them all together to create this particular character.
The fact that he is considered one of the best villains on television just goes to show how terrible he is as a person. People like Joffrey can be seen as a case study in how not to be worthy.
Worthy: Brienne of Tarth
In more ways than one, Brienne is the perfect knight in shining armor. She worked her way through extreme opposition to rise through the ranks, and ultimately managed to become the first woman in the Seven Kingdoms to become a knight.
Her selflessness is absolutely inspiring among so many characters who only care for their own benefits and are willing to betray anybody. After swearing fealty to Lady Catelyn, she does everything in her power to protect the Stark daughters, as a true hero would.
Not Worthy: Petyr Baelish
Baelish is a divisive character if there has ever been one. The sheer cunning he possesses and the way he puts it to use is hard for anyone to not be impressed by. However, at the same time, he is a rather untrustworthy fellow as there is simply no telling what conspiracies he is brewing in his head.
Ultimately, the only thing that can be said for sure about him is that he only ever has his own best interests in mind, and is willing to do whatever it takes to get what he wants. Nevertheless, his characteristics would make for a poor wielder of Mjolnir.
Worthy: Eddard Stark
The first season of GoT did a wonderful job of painting Ned Stark as the protagonist and essentially the apex "good guy". Among other characters whose motivations and actions seemed too dubious to be trustworthy, he was the only one worth rooting for, in a manner of speaking, which just made his quick departure from the plot all the more shocking.
The value of his presence in the world of Westeros becomes clear only after his death. Things only get worse in the world of GoT after the first season, and everybody is left wondering how it would've been if Ned was around.
Not Worthy: Arya Stark
This may come across as blasphemous to all the Arya fans out there, the numbers of which are undoubtedly in millions, which is probably one reason why she got worse and worse over the seasons. The show made her do nearly impossible things and almost made her too perfect.
She starts as arguably the most sympathetic character and ironically goes on to become someone completely lacking any emotion at all. Her behavior may seem badass on the surface, but her quest for vengeance may not be seen as honorable if fans remember how her vengeance consumed her.
Worthy: Jon Snow
Like many of the Starks, Jon Snow is meant to be an embodiment of nobility and honor, so much so that it was almost annoying at times. Even if his girlfriend Ygritte constantly insisted that he knew nothing, the man was a natural leader of virtuous manner who knew when to be strict but never verged on the brink of tyranny or egotism.
He seemed to be the most suitable for the role of king, but as he repeatedly said in the last season, he didn't want it, once again proving his lack of interest in any personal gains.
Unworthy: Daenerys Targaryen
If the last two seasons of GoT were to be wiped from existence, then perhaps Daenerys could be said to be theoretically worthy. Her story of going from a woman forced into a marriage by her manipulative brother to one of the fiercest beings and leaders in Westeros, with her own squad of dragons will always be inspirational. However, it really didn't end on a commendable note. The requisites for being worthy aren't clearly defined, but mass murderers probably don't count.
