To be fair, most of the fan theories out there about the Targaryens revolve around Daenerys. And why not? She's certainly the most attractive, and seemingly most dangerous of all the Targaryens currently living. It would be pretty pointless to still have a theory about Viserys.
But, of course, that doesn't mean that there aren't some interesting theories about other recently discovered Targaryens, or supposed Targaryens, or even Targaryens of old. After all, there's plenty to wonder about Jon Snow (Aegon Targaryen). And how many people think that maybe Tyrion is a Targaryen? And then there's the notion that Aerys was driven mad all those years ago by Bran Stark!
There's no real shortage of fan theories out there about any of the households in Westeros. Dany and her brood certainly have some of the more interesting theories though. So let's dig in and discover what people are saying about those mad Targaryens. Are they a threat? Will they turn on each other? Are they truly blood of the dragon?
15 Dany Becomes The Real Threat
"UncPa57yrzyng points that out because of her disregard for tradition, her unblinking ambition, her ascension as Azor Ahai within a suspicious religion, and her direct opposition to the Starks, she’ll definitely be seen as evil by those she conquers. And she’ll have three dragons to rain down terror from above." Some people jump the gun a little with their theories. After all, Dany hasn't been proven to be Azor Ahai yet, and she only currently has two dragons. Of course, there is also a standing theory that she'll be able to get Viserion back. Though it makes sense that of the dragon, the one named after her brother is the one to be turned against her. Either way, it would be pretty interesting if Dany ultimately became the villain, in spite of her reputation as a liberator.
14 Tyrion Targaryen?
"When he is informed that the dragons haven’t eaten since Dany left the city on their brother Drogon’s back, he is concerned. He informs them that over the centuries dragons grew smaller (no bigger than cats) because they were penned up. When Missandei asks him how he knows that, Tyrion replies, “That’s what I do. I drink and I know things.” We also find out that Tyrion has wanted a dragon since he was a child because he tells this story to Rhaegal and Viserion as he unshackles them." Now, just because Tyrion knows a lot about dragons does not mean that he is in any way a Targaryen, but he does seem to have a way with calming the beasts, so there is some reasoning behind the theory. It would be an interesting connection. Would that mean that Tywin's wife had a fling with a Targaryen?
13 Jon Snow Is Azor Ahai
"The [prince that was promised] is typically used interchangeably with Azor Ahai and other such legends, the general belief being that they all point to the same legendary figure, with the second-coming featuring the same heralding signs (and this is even more likely to be true in the show than books, if the figure does return at all). And while Stannis was Melisandre's first pick, her resurrection of Jon Snow makes him one of the likely options. Given that so many people are presumed to be this savior, the jury is still out on it being Jon Snow. And if it is Snow, then we have to wonder who his Nissa Nissa will be. Will he plunge his blade deep into the heart of Daenerys in order to gain the power to save the realm?
12 Dany Is Jon's Nissa Nissa
"What is often neglected when it comes to Azor Ahai, though, is his wife, Nissa Nissa. After forging metal for 100 days (and this came after previous attempts, using water and then a lion, failed), Azor Ahai drove his sword into the breast of his wife, and was thus able to draw Lightbringer. If Azor Ahai is to be reborn, then will Nissa Nissa too? If so, and Jon is AA, Daenerys is arguably the strongest contender. It'd fit with the ending being bittersweet, and of both Jon and Daenerys having a 'part to play.'" Of course, these two have hooked up, but they haven't married yet. I don't know that they love each other enough to make this story arc believable at present. But that doesn't mean that, by the end of season eight, when everything is dire, that Jon doesn't plunge a sword into Dany's heart.
11 Dany And Tyrion Get Married
"After the coup in Meereen, Dany may just decide that her marriage to Hizdahr zo Loraq isn’t of much value. She may see Tyrion as a more suitable match - if he’s not actually her brother or half-brother that is. And Tyrion would love to vex Cersei with such a marriage."
For starters, this theory has already partially been debunked. Dany has already left Hizdahr. And now she's bedding Jon Snow (her nephew). But that doesn't mean there isn't a future for these characters at all. Even if Tyrion ends up as her half-brother, the Targaryens are known for purposely sleeping with family. And we've already seen the longing looks that Tyrion has given while Dany finds her way into the beds of other men. They may not marry, but it's clear Tyrion wants her.
10 Dany Is Actually Quaithe
"This theory has been around for a while. Dany has the ability to warg and/or to physically time travel into the future or past, so Quaithe is Dany’s self from the future coming to warn her about the destruction of the world."
I'm not quite sure what justification this fan theorist has at all, but it's certainly an interesting thought. I think it's ultimately bullsh*t, but that doesn't mean it couldn't be true. After all, the Wall came down from a single blast of blue zombie flame. Anything is possible in Westeros. I don't recall Dany having the ability to warg like Bran Stark, and I'm pretty sure the only time she's traveled through time was through brief visions...but it's at least still an interesting theory. I don't think it carries any weight though.
9 Jon And Dany Get Married
"This theory states that the two are the embodiment of Fire and Ice and will not only come together to fight the White Walkers, they’ll also create a kind of super bloodline. But many fans do not dig this idea and want to see Jon and Dany as allies and nothing more." There's a reason a lot of fans just want to see these two as allies. After all, they are related. But, as has been pointed out before, the Targaryens have a thing with hooking up with and marrying family. So this would be no shocker. Unless Jon Snow is suddenly disgusted by the idea, having been raised his whole life as a Stark. And there are those people who think that because they are definitely Fire and Ice that they will eventually oppose each other, rather than work together to create a super power or super babies.
8 Bran Stark Is The Reason Aerys Went Mad
"According to one fan theory, Bran’s whispers are what drive the Mad King Aerys to madness. As anyone knowledgeable on Westeros lore knows, the campaign to depose the Targaryens began when he killed Ned Stark’s father and brother, Rickard and Brandon, with fire. Aerys was known for repeatedly saying 'burn them all'. According to the theory, the reason why Aerys keeps repeating that phrase is because Bran traveled back and tried to warn him of the approaching White Walkers. Instead, the whispers only heightened Aerys’ already uncontrollable paranoia."
While this is likely not the case, the show has already given away that it is entirely Bran's messing with people's minds that made Hodor the simpleton everyone knew him as. There is some compelling justification here.
7 Dany Is Azor Ahai
"Maester Aemon told Sam, 'No one ever looked for a girl... It was a prince that was promised, not a princess. Rhaegar I thought… the smoke was from the fire that devoured Summerhall on the day of his birth, the salt from the tears shed for those who died. He shared my belief when he was young, but later he became persuaded that it was his own son who fulfilled the prophecy, for a comet had been seen above King’s Landing on the night Aegon was conceived, and Rhaegar Targaryen was certain the bleeding star had to be a comet.'" Of course, Dany was definitely born in salt and smoke, and her dragons make a good case for her in that regard. And the fact that literally rose out of the flames. But who would then be her Nissa Nissa? Jon Snow?
6 We Will See Khal Drogo Again
"The showrunners, D.B. Weiss and David Benioff, say that Drogo is one of the characters they miss the most. Would they be willing to make the character appear, if only for a brief moment? Many fans would love to see Emilia Clarke and Jason Momoa as Khaleesi and Khal Drogo again. At least we’ll always have season one."
This could be easily done with flashbacks or some sort of vision of Dany's afterlife. But let's not forget that that's not the only way to bring someone back from the dead in Game of Thrones. So many people have escaped death in the show! Arya is somehow alive (though some people think she's the waif). Lady Stoneheart exists in the books (basically zombie Catelyn). Not to mention the fact that zombie dragons and Robert Strong exist. It's entirely possible that Khal Drogo could make another appearance.
5 Is Dany Fireproof?
In an interview with George R. R. Martin back in 1999, someone pitched some interesting questions. And she got answers. But it seems like a lot of people haven't really dug deep to find those answers out today. "...Thanks for asking that. It gives me a chance to clear up a common misconception. TARGARYENS ARE NOT IMMUNE TO FIRE! The birth of Dany's dragons was unique, magical, wonderous, a miracle. She is called The Unburnt because she walked into the flames and lived. But her brother sure as hell wasn't immune to that molten gold." He goes on to say that this likely won't happen again for her. Which means that she could definitely be killed by fire. And given the specific answer of Martin's...I'm wondering if Dany dies via fire...maybe Viserion's zombie flame?
4 Dany Is An Imposter
"Vladith has an interesting theory about Daenerys based on a real-life historical figure, Perkin Warbeck. Martin has drawn from this historical period. Vladith writes, 'Perkin was a Flemish teenager presented to the Burgundian court as Richard, one of the fabled ‘princes of the tower’ ordered to be killed by King Richard III. Claiming to have been raised by Yorkist supporters across the European continent, the hoax posited that Perkin grew up being shipped from city to city, kingdom to kingdom. Initially, Perkin gained support outside of England, but all of his attempts to claim the throne ended in failure, and he was eventually imprisoned and hanged by King Henry VII.'” Could it be that after all of this, the next ruler of Westeros will end up executing Daenerys!?
3 The Dragon Has Three Heads
"In order to bring the House of the Undying prophecy that there will be a dragon with three heads to life, the three will ride Dany’s three dragons. Way more than a theory, fans have been anticipating this moment for a while. Maybe Dany and Tyrion will ride to the Wall and pick up their resurrected nephew and fly off to deal with the Night’s King." Parts of this theory are already dashed. After all, Viserion has been turned into a zombie. However, everyone seems to think that makes Viserion an ice dragon. If that's the case, Jon and Dany together do represent Ice and Fire. So maybe Viserion can be turned back to their side? And we still don't know for sure if Tyrion is a Targaryen or not. But it would be pretty sweet to watch these three flying over Westeros, wreaking havoc.
2 Jon Challenges Dany's Claim
"But could Jon challenge her claim? He'd certainly have a case for it. Although he's Daenerys' nephew, Westeros' succession laws favour male heirs, meaning that, typically, his claim would be stronger than hers." Is it possible that after all of the bonding and love-making that Jon Snow, of all people, could turn his back on Dany? I mean, it wouldn't be the first time that he's killed someone he loved. Just ask Ygritte...oh wait...you can't. Point being, Jon's duty has gotten in the way of his love life already, and if he begins to see himself as the rightful heir to King's Landing, will he turn on Dany if she doesn't bend the knee (in a non-naughty way)? There's a lot yet to be learned in the upcoming, far off, and final season of the show. And way more to learn in the upcoming books.
1 Dany And Jon Are Actually Siblings...
"I've seen people refer to Dany and Jon as brother and sister, cousins, etc. This is not that surprising. The show has drilled into us that Targaryens married brother to sister, and that incest is really not a huge deal in that family. It's natural for fans who aren't paying that close attention to who the Mad King is, versus who Rhaegar is, to assume that Jon and Dany will end up turning out to be long lost siblings, or that their similarity in age means they're first cousins." Some people could make the case that Jon and Dany are actually brother and sister all because of Lyanna Stark, but ultimately, it's not likely that the show is going to change the aunt/nephew relationship they have now. And the evidence for being brother/sister is pretty lame.
