Toph's Baby Daddy/Boyfriend/HusbandTeo?
Random guy with whom she had a fling?
* Probably Ohev, a book-only character who used to work at the Beifong estate and fell in love with Toph.
Lin's father will be revealed the next season as the new Big BadAnd he is none other than the all-powerful Melon Lord! Lin will be forced to become his dragon like her mother.
Lin's father is Thorin Oakenshield, Son of Thrain, Son of Thror.In a brief inter-dimensional Spirit-magic thingy, Toph met Thorin shortly before he tried to reclaim the Lonely Mountain. They sized each other up and after destroying half a city block, they ended up having a fling. Thorin went back and Toph realized she was pregnant. With a little help from Aang and Gandalf, she gave birth to a half-dwarf daughter who looked completely normal so Toph wouldn't have to explain about her child being half-human.
Sokka is Lin's fatherBut it's a big secret. In the midst of the Sokka/ Suki relationship, there came a time when Sokka said something dumb and misgynostic, causing a big fight between him and Suki (Suki probably even calling off the relationship in a fit of temper). Needing woman advice and not able to talk to Katara since she was also mad about said comments, Sokka turned to his buddy Toph, oblivious to the fact that she'd been in love with him for years. Somehow, comforting lead to...other things, resulting in a one night stand. Shortly afterwards, Sokka and Suki made up, and Toph, though secretly heartbroken, assures Sokka they will just be friends. Several months later, Toph discovers she is pregnant. At this point, Sokka and Suki are either engaged or married and Toph refuses to destroy their relationship. She hides the pregnancy as long as she can, and when the news finally gets out, she refuses to say who the father is. The Gaang guess various guys (see above WMG for the list), and Toph never confirms or denies. Sokka either realizes or strongly suspects, but he does not come forward and claim her. Suki does not suspect. Toph raises Lin alone as a single mother. Fast forward about twenty years (give or take), and Lin and Tenzin, longtime childhood friends, develop romantic feelings for each other. When Toph realizes they are getting serious, she is forced to sit them down and explain the truth of Lin's heritage. Lin does not care, but when Tenzin finds out that Lin is really his cousin, he is squicked out and ends the relationship immediately. Alternatively, they both realize they have to end the relationship, but Lin didn't expect him to rebound with Pema so soon.
Lin Beifong got her scars from early attempts at adapting metal cables as a weaponIt's confirmed she developed the technology. If you know just what kind of damage a metal cable under tension is capable of, it's not surprising what a momentary lack of control could cause.
Toph never married; Lin was born out of wedlockIt's entirely fitting for the character, really. Out of all the Gaang, Toph would be my bet for "least likely to get married" (and not just because she's one of the few characters not explicitly paired up by the end), but I imagine she'd also be pretty open to one-night stands or short relationships. It also explains why Lin took her mother's last name. Alternate Theory: Toph reproduced by parthenogenesis
Chief Lin Beifong did not get along with Toph.I could see it happening - a strained relationship between the parent and child... Beifong family tradition, perhaps? Lin's attitude just seems in so many ways different from Toph's... Although they do have certain similarities. I feel like they've had their fair share of disagreements as mother and daughter though. Maybe, at one point in the series, Lin will stare up at that giant statue of her mother located at police HQ.. And some kind of scene will occur. Perhaps involving Tenzin.
Chief Lin Beifong is actually Toph's adopted daughterThis troper can't really picture Toph settling down with anyone for long enough to have a daughter. Plus, it could help make a point about non-bender oppression: Toph could have specifically sought out a baby who showed strong earthbending potential, so she could raise another metalbender. It seems like something that could become a common trend - if you bend an element, wouldn't you want a kid with potential to bend the same thing?
Lin Beifong's FATHER died during childbirthIt makes it a moot point as to who he was. It says enough on its own
Lin's "Father" is Azula!
Lin arrested Aang at least once while he was still alive.Avatars don't seem to impress her much. And besides, breaking all those cabbage carts had to catch up with Aang at some point.
Wei Beifong is Chief Beifong's daughter and a non-bender.Aang and Katara have grandchildren in LoK, why couldn't Toph? And as for the non-bender part, consider this theory. Imagine you're the heir to a famous line of powerful earthbenders, your grandmother was a war hero and your mother is a decorated police officer, only you can't bend. Lots of angsty possibilities there, especially if she fell in with a bad crowd. And it be something of a deconstruction of the fanbase's idolization of Toph, by showing what it's like to live in the shadow of such badassness.
Lin Beifong doesn't like Korra because she blames the Avatar for her mother's death
We will meet Firelord ZutaraZuko and Mai wanted to name their daughter after the woman who saved Zuko's life and kicked Azula's ass, but, since 'Katara' was too Water Tribe-y for the heir to the throne, they gave the name a Fire Nation twist. Incidentally, this now means Kataang, Maiko, and Zutara are all canon.
Zuko's Great-grandson will be the Blue SpiritHe will be a sort of robin hood figure and Korra will meet him while he's stealing from her. He's either been disowned or sent by his Grandfather on a journey like he was. May or may not be a fire bender.
There will be a circus troupe ran by Ty Lee's daughter.Because of course.
We will meet either Teo or one of his descendants...And he will be a knock-off of Dr. Weird. Why? ...Why not?
At least one of the Gaang's descendants is on the United Republic Council alongside Tenzin.Sokka, being the next Water Chief, probably has a son on the council. What I am wondering the most about is who is representing the Northern Water Tribe. Yue was an only child. Who did the icy crown succeed to?
Aang's elder children, Kya and Bumi, are EqualistsOf Aang's three children, only Tenzin was an airbender. Therefor Aang might have favored him more and caused the other two to become jealous and hate all bending.
One of Aang's non-bending children will turn out to be Amon.So far, we only know that of Aang's children, Tenzin is the airbender. What better cause for a slow build of rage and resentment towards benders than a child of the Avatar who saved the world, who is ignored by the world JUST because he doesn't have the same magical powers as his parents and younger brother? It would be another very interesting angle on Aang's family and would make for a fun dynamic between Amon and Tenzin.
Aang's son Bumi will be introduced as a slimpy antagonist.Look at the guy. He looks pretty shifty and untrustworthy. He'll probably appear like an Equalist sympathizer who doesn't get along with his siblings, and Korra will catch him doing some shady deals with them, but no-one will believe her. In the end she'll confront him personally...and find out that he belongs to Chief Beifong's secret police and has been trying to catch Amon for months when she blows his cover. Seriously, remember who this guy is named after, and what first impression he gave??
Amon is Lin's father.With all the wild speculation as to each of their identities...it would be bizarrely appropriate.
Bumi ISN'T Amon but the team believes he is.
Lin Beifong's scarsLin got them from the same insident that killed Toph.
Lin Beifong will frequently suffer The Worf Effect several more times in the futureShe fails to avert the terrorist attack on the Probending Arena in Episode 6 and is devastated when she fails to arrest Hiroshi Sato and can't save her men, so it seems she is being built up to this in the series. Given it is only seven episodes in, she will likely get defeated or outsmarted several more times in the future of the series.
Kya lives in the South Pole.She is a waterbender, and it's only logical for her to live there so that her mother wouldn't be alone in her old age.
Either Bumi or Kya have an airbender child.Hey, they both have the potential. When the child gets older, s/he will be sent to live with Tenzin for a while so they could master their airbending abilities.
Lin will teach Bolin classical earthbending and metalbendingShe certainly has the time to do so now that she resigned and Bolin's earthbending could do some work so who better than learn it from the one who was taught by the best?
Kya lives in the North Pole training a CIA/Navy SEAL (pun not intended) Amazon BrigadeTo show progress from the NP's old mindset, Kya trains the women from merely healers to Combat Medics, namely in Bloodbending to do the "less-popular" jobs (yeah, yeah "wet work") that initially are thought of only as a myth/joke by the ladies being ridiculously girly only to don camo at night and "get results." Kya will only be really involved when the Equalists become seen as global threats about to spill out into the rest of the world where is guarding the coast as an admiral waiting for the signal from the Krew.
Bumi is not an antagonist, but merely a Brilliant but Lazy party boyInstead of all the theories of him being Amon/An Equalist where he has "Bender Envy" ("I'm the son of the Avatar/greatest heroes of our generation and my siblings are powerful benders!") he's thinks not being a bender frees him of responsibilities ("I'm not a bender? PARTY TIME!) like being a Jackson not named Janet or Michael or a Kennedy not involved in politics, but liking the name recognition anyway. He's intro'd with a ''lot'' of women on his big arms, calling Tenzin "Tenz/Tenzy," Beifong "Rock Queen," etc., and basically being Big Fun that Bolin is/wants to be when he's that age with a talent for machines instead like Uncle Sokka, but a Cowardly Lion/ Lazy Bum that wants to avoid conflict as much as possible. Asami calls him out on that as a fellow non-bender that he's just as valuable/responsible as her in fighting the Equalists, proving it against them like Katara inspired the earthbenders to rebel on that ship. He pulls a Big Damn Heroes to assist and becomes her sensei like Piandao to Sokka, provides vehicles to anti-Equalist non-benders and especially a (marketable) tricked-out Cool Car and/or motorcycle for Asami to replace the read roadster Korra got that's more combat-orient for epic vehicle battles.
Bumi is a multi-skilled Badass Normal and currently owns Sokka's Space SwordDoubling as a Call Back, Bumi likely learned a variety of skills to make up for a lack of bending, and probably spent the time traversing the world to learn, discovering the Sword covered in vines and plants. To add more, he learned the normal Water Tribe skills of tracking, weapons, and sarcasm. If he spent time with Sokka especially, he likely learned chi-blocking from the Kyoshi warriors. Since he was named after the Trickster Mentor himself, he likely took the time to be the type who would think outside the box and resort to using wits and creativity. In general, he's a Memetic Badass waiting to appear in Republic City.
Lin will dieDoes no one else feel that she's being set up for this?
The thing that put strain on Tenzin and Lin's relationship wasHe wanted children. She didn't. Tenzin, as the last airbender would have felt a responsibility to have children and keep airbending alive. But Lin wasn't sure she wanted to start a family. This gradually put a strain, and a wedge in their relationship.
Lin's father will never be revealedBryke are magnificent trolls, and therefore they shall either wait until the series is almost over or leave the fandom clueless forever.
Sokka taught Bumi how to use a boomerangHe also taught him that you don't have to be a bender to be a badass. In the event that Sokka didn't have any kids of his own (or his kids simply weren't interested), he left his boomerang to Bumi when he passed away.
Zuko's daughter's name isZutara.
The next Earthbending Avatar...Will be Lin's great-great-grandson, and be a Handsome Lech who tries to slack off from his duties as Avatar. He'll be accompanied by a young Firebending man with a hot-headed personality and a young Waterbending girl with an icy personality. His Airbending teacher will be Meelo, who's become quite the Cool Old Guy.
Lin's scars came from her mother.Toph is a firm believer in the school of hard knocks, and wouldn't hold back even in a sparring match. Especially if Lin was a recruit to the Metalbending Police, and she had to show both her and other recruits that her daughter would get no special treatment from her. Those twin scars definately look like they came from a metalbender's double whip.
Zuko's son is the firebender who killed Amon's family, possibly the same one who killed Mako and Bolin's parents as well as Asami's mother.Dante Basco said that he would do the voice for a character related to Zuko whom we would not expect. His voice is going to be in an episode entitled "Skeletons in the Closet". I think this episode will be about Amon's past. Dante Basco will voice Zuko's son. This also explains why Zuko's daughter is Fire Lord and not his son as is tradition. His son was an extorting, parent murdering, and child's face-burning monster.
Zuko's daughterDante Basco said that he would do the voice for a character related to Zuko whom we would not expect, and would you really expect Basco to voice the daughter of Zuko?
Zuko's daughter is named Ursa.
Iroh II is a badass nonbender.He'd be the perfect opponent for Amon.
Bumi is also a general for the United Forces.Look at this image.◊ They seem to be wearing the same clothes.
Bumi is Iroh II's father.His clothes actually look like they're Fire Nation. Bumi was not born into the Fire Nation, being the son of an airbender and a warterbender. This implies that he married into the Fire Nation. Also, his clothes are probably pretty high ranking. Like the other WMG says, possible general status. It's possible that Bumi married Zuko's daughter and then had Iroh as a son. This wouldn't be the first time the Avatar and the Fire Lord would have mixed bloodlines. This also points towards the direction of Iroh II being a badass nonbender if his father is a nonbender as well. This is just too awesome to pass up.
Iroh II is a childhood friend of Korra's and yet another segment of the Love Dodecahedron.
Iron II is the reincarnation of Uncle Iroh
Bumi is a master of all 4 elemental bending formsIt started when Bumi was a kid before Tenzin was born, Aang was worried that he really would be the last Air bender, so little Bumi asked his daddy to teach him some moves which he picked up on quickly. Bumi and Aang bonded over this and after a while he had the idea to ask his mom the same thing. By the time he was a young man he was as skilled in 2 elements as any bender and profichient in the other 2 thanks to Aunt Greatest Earthbender EVER Uncle Firelord. He took the time to master the other 2 and on weekends he would train with his father.Plus the bending arts are based on martial arts and even without the ability to move elements they are handy in a fight.
Iroh II is Azula's sonWe know he's related to Zuko but we don't know how. Maybe Azula did get redemption at some point, settled down and had a family. It's extremely unlikely, but look where we are
Lin wasn't Toph's only childLin is about the same age as Tenzin, and he was the youngest child three; it's not too much of a stretch to think Lin has some older siblings - more badass metalbending Beifongs. Though I hope this doesn't lead to a suspiciously similar substitute...
General Iroh is not Iroh2He's Iroh 3rd, Zuko named his son Iroh and he named his son Iroh.
Lin will not get her bending back, but will continue to fight regardless.In this recent interview, Bryke make a very big deal of Lin's sacrifice in "Turning the Tides", and how it serves as the climactic moment of her character arc and her ultimate act of loyalty to Tenzin and the others— it would be rather poor form for them to just hit the Reset Button and give her and everyone else who lost it their bending back. However, given her personality, there's also no way that she'd be willing to just lay down, even after losing her powers; she'd continue training and become a Badass Normal, and keep on fighting for Republic City.
At one point, Lin was offered a position to be a high-ranking leader in the United Forces.But she denied it in preference to her position as a police chief to honor her mother.
Gommu is Sokka's son.We haven't seen his descendents yet (as far as we know) and that's a pretty obvious gap. Until someone else comes along, this troper says the hobo makes perfect sense.
Iroh II will be AdorkableHe would be following in his grandpa's footsteps with this. It also makes sense considering that a general wouldn't have a lot of time for social interaction.
Zuko had only daughtersWe know for a fact that his one confirmed child is his daughter the current Fire Lord, who's either Iroh II's mother ot aunt. She was either Zuko's only child or his other children were also women because surely he would have named his son Iroh II rather letting it wait a generation. And no, the fact that the current Fire Lord is a woman does not in itself prove this since surely Zuko is cool enough to be gender-blind when he chooses his successor, rather than using the arcanic "Only a female heir if their is no other male heir available"-rule.
Aang is Lin's fatherWhen Toph was in her 30's and going nowhere she asked Aang to be the father but Toph raised Lin solo and with neither ever telling the kids, until the parents got word their kids were dating.
Zuko's daughter is named ZuzuAs a callback to the series Zuko will name his daughter Zuzu
Bumi was supposed to be named after Monk GyatsoHowever, King Bumi died shortly before Bumi was born (and since this is King Bumi, the way he died would have been completely insane but awesome, as he laughed and enjoyed himself all the way until his final breath). Once Aang got over the mourning period for the loss of his friend, he felt he needed to honour his old friend and when his next son was born, Aang thought what was a better a way to honour his friend than to name his kid after him?
Gommu (the hobo) is descended from Dock/Xu/Bushi (the multiple personality guy from the Painted Lady episode)
Wei Bei-fong is Lin's fathera random character who's name was mentioned but he never showed up, who happens to share the families last name? Yeah, that's my only evidence, but this is a WMG
