They are the offspring of King Bumi and AzulaOh, yeah. So, basically, King Bumi rescued Azula from prison and they fell desperately in love. Wow... this theory sounded funnier and less perverted in my mind.
Katara will be implied to be a Yaoi Fangirl for them
Bolin and Mako are Ursa's grandchildren...When she was banished, Ursa probably hid out in the Earth Kingdom somewhere. Eventually, she remarried an Earthbender man. They had at least one child who relocated to the United Republic, who later had Bolin and Mako, an earthbender and firebender, respectively.
Similar to above, Mako and Bolin are somehow related to Zuko.Mako looks similar to Zuko. Bolin and Mako's names follow a small trend from the royal family. S"O"zin, "O"zai, Ir"O"h, Zuk"O", B"O"lin, Mak"O". They all have the OH sound. And before anyone just says it's a tribute to Mako(the voice actor), Two Birds, One Stone. Zuko, the grandson of Roku(again, a hard OH), Traveled with the Avatar. Now, perhaps, HIS grandsons travel with the next Avatar.
Mako and Bolin are Azula's grandsons.Azula recovered from her insanity some time after the War ended, and traveled the Earth Kingdom as The Atoner during the turbulent days between her father's defeat and the founding of Republic City. There, she met Haru, fell in love with him and his smexy mustache, and married him. At least one child and one in-law later, here come Mako and Bolin. Maybe they have a firebender father/uncle/cousin who is voiced by Dante Basco.
Mako and Bolin are Lu Ten grandsons, Iroh's great-grandsons.Inheriting both Iroh's open-mindedness and his charisma, Lu Ten had a secret romance with an Earth Kingdom girl. Being a member of the Royal family, directly in line for the throne, his combat abilities would be comparable to Ozai, Iroh, Zuko and Azula. Also, being a prince, he was probably kept way from the most dangerous fighting. The reason he was killed was because he was unfocused and emotionally conflicted, torn between his duty and his feelings. With Lu Ten dead, and either pregnant or having given birth to a child fathered by "the enemy," the mother would have been pressured into leaving her home, with her child. The mother and child would have been homeless, until eventually moving to Republic City, somewhere they could finally be accepted. While till very poor, possibly still homeless, Lu Ten's child was still able to have a family, Mako and Bolin. This would explain Mako's very impressive firebending abilities, being able to win 3v1, assuming bending proficiency is inheritable. It would also make a connection between Mako and the man he is named after, Iroh's voice actor. It would also make quite an interesting backstory, making these street rats directly related to royalty, as well as creating a connection to the previous series.
Mako and Bolin will have a family name.Republic City is densely populated enough that single names wouldn't be sufficient to organize society, surnames will have been adopted by the general populace.
Amon is Mako and Bolin's older brother.When their parent(s) dropped them off at the orphanage, Mako and Bolin were separated from their older brother because they were benders. Due to the special needs of young benders, they get segregated from the non-bender orphans. Can't have them setting the bed sheets on fire and whatnot. A heartbroken Amon (not his name) came to resent his brothers when they were adopted and he wasn't, because their new parents only wanted benders. While Mako and Bolin ran away from this couple for whatever reason, Amon had escaped the orphanage and joined a non-bender gang that trains him in chi-blocking. So the episode titled "The Skeleton in the Closet"? That skeleton is in Mako and Bolin's closet, and it's their brother Amon. Although Korra either won't find out about this until much later, or will learn it but agree to keep it quiet to protect Mako and Bolin's reputation.
Mako won't believe in the traditional Fire Nation concept of honor. Bolin, however, will.Stemming from the multicultural angle of the show, Mako's personal belief won't lie up entirely with what we've come to expect from a traditional firebender. Growing up in a republican society rather than a feudal one, and among people of many cultures, Mako won't put any stock in the notion of honor. Instead Bolin will, as a way to tie himself to whichever parent of theirs is ethnically Fire. This division between the brothers, and their respective beliefs, will catch them flak from the more traditionally minded members of their native elements: Mako for not measuring up to what a "real" man should be, Bolin for acting like he's Fire Nation.
Mako will be Bi.And thus Yaoi Fangirl Korra will have a very satisfying relationship with her BF indeed.
Mako will apply the technique of bending lightning in new ways.From what we've seen, Republic City is a sizable metropolis, and with the series being set in 20's of the Avatar 'verse, it's not a stretch to imagine that there are electric lights and other such devices present within the city. At some point, either via his own merits or by being taught by someone else, our party's resident firebender will gain the ability to influence electric technology with his bending. This could have numerous applications; halting the current in a wire shuts down an electric machine, sending a jolt of power through a device overloads (and explodes) it, stopping and starting the flow of current in lights is used for signaling purposes, etc. Such a skill would invariably prove useful to the party, and would just be cool as hell.
Mako is Koh.Only thing I have going for this is the pronunciation of Mako's name, Ma-koh. I'm aware of the Meaningful Name, but nothing says that honoring Mako has to be the only meaning. It's been a full Avatar Cycle since Kuruk tried to kill Koh, so maybe he doesn't care about that anymore. Mako could be Koh's temporary human form, and through a friendship with Korra he can be certain this Water Tribe Avatar won't be as lazy as Kuruk.
Bolin will end up joining the Equalists
Bolin will use Pabu to flirt with girls.Bolin is a ladies man, and who can resist a Ridiculously Cute Critter like Pabu?
Mako and Bolin were Triad enforcersWhen looking for Bolin in the latest online clip Mako's first instinct is to check the Triad headquarters. He knows where those headquarters are and he seems unusually familiar with Triad protocol. This troper thinks that Mako and Bolin used to work as muscle, perhaps even high-ranking muscle, for the Triple Threats and used the money they earned there as a stepping stone to becoming pro-benders. That might also be why the fabulous bending brothers are such a dominant team. They earned those bending skills by fighting for their lives in the back alleys of Republic City.
Mako and Bolin are Zuko and Mai's grandchildrenMai and Zuko's child was a firebender, who maried an earthbender, and they they had two sons. Mako looks a lot like Zuko.
Mako and Bolin are actually waterbenders. Also Mako is actually Amon and Bolin is the true avatarThere is no such person as "Amon". Just some poor random guy Mako takes complete and utter control over as a puppet for his firebender-hating agenda, using his extremely advanced bloodbending. Think about it: exact same back-story, except with an additional "scarring" in "Amon"'s case as a convenient way to just grab any ol Joe off the street and sticking a mask on him without arousing suspicion. As for Mako's "firebending", all he's doing is imitating firebending forms and super-heating water vapor to incandescence using his insanely powerful waterbending to look like he's a firebender, thus deflecting any suspicion that he's the mastermind behind "Amon" through bloodbending. Bolin knows all of this, but he plays along because he's FUCKING TERRIFIED of Mako and his beyond-Azula levels of crazy nastiness. Also Bolin is the real avatar. Korra can bend three elements because a lionturtle secretly visited her at birth and used spiritbending to give her the ability to earth- and firebend, just to troll people. This explains why she has such trouble airbending: because she CAN'T. Bolin is a waterbending avatar. He just doesn't know it because everyone already thinks Korra's the avatar. He just thinks he's an earthbender because, for some weird reason, he only ever bends the water in the hydrated silica in the crystal structures of rocks.
Mako and Bolin's parents were both earthbenders.Or, at least Bolin's were. Mako and Bolin's father wasn't really Mako's biological father because their mother had an affair with a firebender, resulting in Mako's conception, but it was broken off at some point before Bolin was conceived and her husband was oblivious because Mako hadn't begun to bend yet (or if he did, he kept a secret, perhaps because his mother asked him to). Mako's biological father may or may not have been Zuko's son.
Mako and Bolin are not actually blood-related.
The death of Mako and Bolin's parentsI've got a couple thoughts concerning the nature in which they died and the intent behind their deaths. Keep in mind, part of this theory resulted from drawing comparisons between Mako and Bolin's parents and the Waynes, which is integral. One has to wonder if Mako witnessed his parents getting burned to death or getting electrocuted to death. Lightning bending has become a mundane skill, evidenced by Mako and many other firebenders who use it to power generators for work. It would take less time to take down a target with lightning, especially if said targets are benders—one of which, a firebender. Mako and Bolin's parents would have fought back the moment they saw they were in danger. Getting killed by electrocution is faster and less noticeable, as getting killed by fire would mean that the fight was drawn out, leading to possible witnesses and at the most the police being notified. In either case, the couple slipped up in trying to defend each other and the boys, ending in their deaths. Of course, Mako and Bolin's parents may have been snuck up on, having no chance to fight back. Either way, Mako would have witnessed his parents die a horrible way (and God forbid Bolin witnessing it too, who was even younger at the time). But what if this wasn't just your usual mugging with a desperate firebender looking for a way to make a quick yuan? What if, like in some versions of the death of the Waynes, that mugging was just a disguise for murder? Or what if it was just that—murder—and Mako never realized it? A murder seems likely, as a mugging ending up in murder unintentionally seems improbable, at least not in the conventional sense. Any form of resistance would have resulted in a scuffle, and with bending involved it would have gathered too much attention unless dealt with swiftly, as stated above. We don't know enough to know if the perpetrator was ever caught, or if Mako didn't tell Korra the entire truth if he knew more than he let on. What I do know is, for two benders to be killed by a firebender without much of a fight in a mugging is much more unlikely than it being intentional, planned out murder. In my eyes, their deaths has become a great mystery I hope the show explores. One has to wonder exactly who they were and if there was any reason behind their deaths beyond it just being another unfortunate casualty in Republic City. Were they just a couple who ended up as unfortunate casualties marking the corruption and crime in Republic City? Or were they people of significance intentionally sought out to be killed?
Mako and Bolin spend the other half of Season One (or Part of Season Two) learning the spiritual aspect of bending and become stronger to help KorraBecause of the Equalists, they will be required to live with Korra and the Air Nomads, taking the now free time they have to learn about the history and origins behind their bending. By embracing the spiritual side of their bending and training on the Island with Korra while the Arena (which was where their home was) is being repaired, the two brothers' will have more powerful bending and become better fighters as a whole to help Korra counter the Equalists.
In book 2: Spirit, Bolin will be possesed by an evil spirit.Such evil spirit will bring out his darker side and fight mako, exploiting his hidden jelousy for his brother and it will make him a formidable foe.
Bolin will take a level in badass and invent or rediscover a technique or specialized type of earthbendingCalling it now. Bolin will rediscover magma bending, making him one of the strongest earthbenders of his era.
Mako and Bolin do have a surviving aunt or uncle.However, this relative is an Equalist who disowned their sibling long ago for either being a bender, marrying a bender, or having bender children. Mako and Bolin will find out about this relative and be eager to meet them, only to end up disappointed and crushed that their only other surviving family members want nothing to do with them.
Mako is building up to becoming a sympathetic villainIn episode seven, he was pretty much a world-class jerk. He claimed Korra accused Hiroshi Sato of being Equalist-aligned because she was jealous of him and Asami, and he threatened to break off his and Korra's friendship because of it. However, at the end of the episode, when it turns out Korra is right, he swings right back around to being nice to her. This troper thinks this is some sort of foreshadowing of Mako's character. Maybe he won't turn into a straight-up villain, but maybe he will become someone who is definitely not a friendly.
Mako and Bolin are Sokka's and Suki's grandchildren.Bolin is too like Sokka for this to not be true.
Mako and Bolin are going to run into some old Triple Threat Triad friends in prison.And Asami is NOT going to be happy about Mako's criminal past.
Mako will die before series end.His will be a most epic death, probably with a "Facing the Bullets" One-Liner or a Taking You with Me. This might happen for two reasons: It could work as Bryke's tribute to Mr. Iwamatsu, giving his eponymous character a viking funeral. The second reason: Bryke enjoys crushing shippers' dreams. What better way to solve the Love Dodecahedrons' detailed in other guesses than to have at least one be all for naught? The second season will see Asami and Korra grieving Mako's loss together, and becoming closer friends in the process.
Mako will be separated from the rest of the group.Whether by death, willingly parting ways, or unwillingly parting ways, he'll be away from Korra and co. for a long time. The love triangle will cease to be a big issue for Asami and Korra, Bolin will come into his own, and Mako may or may not grow as a person too from the experience.
Bolin will learn how to Metalbend in Season 2 or become a Metalbender Cop at the end of the seriesHe has been trying his best to show he is a competent member of the team and is a skilled Earthbender. This would be a good marker to show his skill development, his potential, and many ladies would swoon over a man in uniform.
Bolin will be mentored by LinNuff said.
Either Mako or Bolin (either one really) will idolize ZukoIt just makes sense, especially considering that they hung out around Zuko's statue. Mako will be almost as awkward as he was with Asami when he finally meets him. Also, on a related note...
Mako will be mentored by ZukoGetting lessons from the most powerful firebender in the world could be quite appealing to both him and Team Avatar. Plus, the lessons from Zuko as a Badass Grandpa are just too awesome to pass up.
Mako doesn't have romantic feelings for Korra, but he has his own reasons for being so upset.Compared to the other characters, Mako reacted a lot more strongly to Korra's kidnapping. Characters in the show, as well as real life shippers, see it as evidence of Mako having romantic feelings for Korra. But remember, Mako is an orphan and only has one family member, his brother. Bolin has probably had many close calls himself. Mako is more emotional about Korra's disappearance because he can't bear to lose anyone close to him. Bolin was likely young when their parents died and probably doesn't remember the event much.
Bolin is the reincarnation of Sokka.Someone mentioned above that Bolin was Sokka's grandson, but I think it goes beyond that. In the episode that explored Avatar Roku's life in Legend of Aang, it was heavily implied that the Avatar's close friends are reincarnated along with him/her. So while some of them may be still alive, those that have died have reincarnated into newer members of the Gaang. Bolin, being rather comedic most of the time, is a good fit for Sokka. We just haven't seen the Deadpan Snarker side of him yet.
The prosecutor at Yakone's trial was Bolin and Mako's grandmother.There's really no reason why. Just an idea I had. But since we never hear about her, she may have gotten whacked when Yakone escaped from jail....
Bolin is not as heterosexual as we have been led to believe.But he's not exactly gay either
Mako and Bolin (or at least the Fire Nation side of their family) are descended from Chan.Remember when Azula and friends burned down his house? Perhaps his family moved somewhere else afterwards.
Bolin will end up with Korra's female cousin.She'll think he's immature and beneath her at first and he'll think she's stuffy and less fun than even Mako. Something'll happen that'll end with them becoming unlikely friends and they'll just go from there.
Mako's joining of the Republic City Police in Book 2 will result in more non-metalbenders joining as well.Just a thought. It seems likely, especially given how Mako himself seems to flourish in his new job in the animatic shown at SDCC; one would imagine increasing the diversity of their bending forces would be a good thing.
Bolin's new Fire Ferrets will have a rematch with Tahno's team at some point in Book 2.And this time, it'll be a fair fight— and the Fire Ferrets will get their long-deserved victory over the Wolfbats.
Mako is the one who killed his parents.It was an accident, and Mako's in horrible denial about it.
Mako & Bolin's Firebending parent killed their Earthbending parent, and then themselves in remorse.Perhaps whoever was the Earthbender had an affair and then the Firebender flew into a fit of jealous rage, but instantly regretted it when when the deed was done and killed themselves. Perhaps it was some sort of awful Sophie's Choice like scenario where some outside force (the Triple Threat Triads, the Equalists, or something else) forced the to either kill their lover or their children and they killed their lover and then themselves. It could have been a suicide pact, also including the kids, but Mako managed to safe himself and Bolin. Regardless, Mako knows the details but Bolin doesn't remember as much.
Either Mako or Bolin was adoptedIf Mako was the adopted child, it's possible Bolin's mother had many complications during childbirth. So his parents assumed that they'd never be able to conceive a child (this is prior of Bolin's birth). They adopted Mako at a young age, and just a year earlier before Bolin would be conceived. Consider him a "miracle child" who was born through almost impossible odds and was lucky to be alive, even moreso to be born without any permenant health issues either. The fire bender who would then killed Mako and Bolin's parents wasn't just any mugger. They were either racist, and were against the idea of some earth-bending family "tainting" a fire-bender. Or the mugger may have been Mako's bilogical parent who had Mako taken away due to being considered a bad parent (the parent may have been abusive or an alcoholic and would mistreat Mako when drunk), and they killed Mako's adoptive parents in a fit of rage. If Bolin was the adopted child, Mako's parents probably worked for the Triple Threat Triad, and one of their jobs had them killing a prominent earth-bending family that stood in the Triad's way. Bolin was only a baby at the time, and as they had a son of their own, they couldn't bare to kill an innocent baby who wouldn't remember the event, so they took Bolin and raised him as their own child. However, years later someone higher up in the Triple Threat Triad found out that Mako and Bolin's parents didn't completely put an end to Bolin's bilogical family, and as they worried that Bolin may found out about his real parents that he could want revenge, they couldn't just ignore this. So they sent a fire bender to kill the family. Mako and Bolin just managed to escape while their parents held off the fire bender long enough for them (before they were killed). Why the Triple Threat Triad didn't try to kill them though when Mako and Bolin were working for them? It would have been a very long time after when the two were old enough to seek the Triad out for work, so no one in the Triad ever recognised them as the children who got away that one night years ago. The Triade may have also never had anyone who knew what Mako and Bolin looked like in the first place either when they were children, so it would have been difficult to see any connection. The fact that one of them was adopted never came up in the series isn't because they don't know, Mako and Bolin are aware of this just that they don't care. They're still brothers and they don't believe it matters that they're not related by blood. It'll probably come up if they'll ever be asked specifically about this.
Bolin's character development will cause many conflicts between he and Mako to get thereIt's obvious that Mako is the more mature of the two, and as the older we can assume he was always looking out for Bolin when they were growing up on the streets. Considering how Bolin is so optimistic and naive despite going through the same hardships as Mako, it's very possible that Mako, in his own way, has been trying to shelter Bolin because he still only views him as his "kid brother". As the series progresses, Bolin is going to mature become less naive. Particularly after an event where something Bolin has done has caused Mako to be kidnapped by the new thread in the second season, and Bolin starts to fret that he may have lost Mako for good. This will lead to Bolin doing more risky tasks to pull his weight in helping the Krew more. Mako will start to nag Bolin over the increasingly dangerous things he's taking on, and it'll cause arguments where Bolin complains about how Mako has to learn to trust that he can handle himself more and to stop being protective of him all the time. These arguments will persist and it may look like they can't get back make-up over these arguments. By the final of the second season, they'll both be put into a life or death situation and they only get out of it alive by reconciling. In the end, Mako will begin to realise that Bolin is more responsible than he gave him credit for, and Bolin will realise that Mako is only protective of him because he loves him and not just because he doesn't think Bolin can handle things for himself.
Mako and Bolin are the children of Hope and Tom Tom.Unfortunately this means that those two cute little kids are now dead... That really sucks.
Mako will have a Take That, Scrappy! moment.Here's a hypothetical scenario.
Mako will consult with Katara at some point.Much like how only another Avatar can be a good consultant on how to be an Avatar, only another Avatar's significant other can have any good advice on how to be romantically involved with someone with such awesome power and important duties.
Varrick will try to make Bolin a bad guy too.It just wouldn't make sense for Varrick to build him up and make the people of Republic City love him if Bolin can then turn them against him when he is ousted as a villain.
Bolin will reference Nuktuk in some way, shape, or form if he ever fights the real Unalaq.Whether it'll be fighting him in costume, acting fully in character, or even just a passing reference, it's gonna happen. Bonus points if one of Nuktuk's fans is witnessing it. Even more if said fan makes some comment about "Nuktuk" being an Earthbender.
Bolin will become a mentor or uncle figure of the next Avatar.Roku (Fire) was good friends of Gyatso (Air), and when Aang (Air) was born, Gyatso became a mentor and also Aang's teacher. Then Aang became close with Katara (Water), and when Korra (Water) was born Katara was the one who taught Korra waterbending. So, let's say the pattern continues. That means one of Korra's friends as an Earthbender would be the next avatar's teacher (and the next Avatar is going to be of the Earth Kingdom)... and guess who's right there? Bolin, the first person outside of Korra's life in the compound who she could talk too and as their 'date' scene indicated they are good friends. Plus, who doesn't want to see Bolin age into a Cool Old Guy and a Big Fun? Be an awesome contrast to the last two Earthbending teachers we've seen (Roku's teacher Sud and Toph) who are pretty much hardasses (though with a sense of humor), and would be an excellent way to act as a tie to anything set in the future. Double points for this if Korra asks Bolin to help take care of the next Avatar by learning from the mistakes made with her if the next one is found too early.
Mako will resign in disgust from the RCPD.After being wrongfully accused of being a dirty cop and then having his name cleared, he becomes disillusioned with Chief Beifong and tells her to keep the badge as she's reinstating him, stating that he's quitting. Asami then hires him on as a corporate security officer in Future Industries.
