Is Hiccup a Badass Pacifist because of the trauma that resulted from him and Toothless killing the Red Death? Or is it simply him trying to impose an unrealistic ideal on an imperfect world?
Alvin explains that he got banished from Berk for causing casualties by disobeying orders (probably unintentional) and is now quite willing to let Berkians like Hiccup get eaten by dragons (unambiguously intentional). Did he become more hard-hearted over time, or did Stoick see the ugly side of him?
Mala provides an in-universe in regards to Berk—she questions whether Hiccup and his riders fly WITH the dragons or have in a way subjugated them via a softer hand.
Averted with Hiccup. He still has some lingering self-esteem and image problems that he had in the movie. Seeing as he was ostracized by his entire community up until recently, this is very understandable. Played straight, however, with Hiccup seemingly having no issues whatsoever with his prosthetic foot. Any comment he makes about it is incredibly snarky, but with no trace of angst.
Considering that most of the adult men of Berk have at least one prosthetic, this isn't all that surprising. Losing a limb seems more like a mark of pride than anything else in their culture.
Averted with Heather. For good reason, she has a lot of baggage especially after Dagur kills her parents, then later finds out he's actually her brother.
After the second film was directed by someone who had no involvement with the series and openly stated he made no effort to keep it canon, Race to the Edge goes to some lengths to reconcile the differences so people aren't forced to choose which canon they prefer.
Ruffnut in the first season got less screentime and dialogue because her voice actress couldn't keep up with TJ Miller's improv, much to a lot of fans' ire. Come season four, she has about several episodes focusing on her relationships with the other riders.
Likewise, the viewers noticed that Hiccup had little to no leg problems given his amputation and it sometimes doubles as a Disability Superpower. In season four, one episode has a Running Gag of Hiccup getting his prosthetics damaged.
Heather. Her introduction immediately triggered Die for Our Ship from the Hiccstrid shippers, more so when she predictably turned out to be The Mole for Alvin, only to redeem herself on saving the riders to rescue her parents. Quite a few fans appreciated her having layers of character depth, and a willingness to play dirty. In Race to the Edge, while she is cooler with her axe and improved combat skills, as well as taming a dragon whose spines can kill men in one shot, part of the fanbase points out that, like most Mary Sue characters, she makes a lot of mistakes in her initial episodes, does things the way she wants, and manipulates the riders, but they tend to treat her well.
Stoick. The. Vast. To a good portion of the fanbase, he counts as an Abusive Parent due to his tough words to Hiccup in the movie, and occasionally in the show. To another portion, he represents Parents as People who has to balance his job as chief and father.
Dagur's new look as of "Race to the Edge". While most admit the shorter-hair-after-being-a-prisoner is pretty accurate, a lot of people do not like the beard. And even those who don't mind the idea of Dagur growing a beard don't like how patchy his is. And people apparently really miss his Loki-helmet.
Heather and Fishleg's getting Ship Tease in season three of Race to the Edge, on the one hand both are popular characters that could use the focus, on the other given that the show makes strides to stay in the canon of the movies this means that no matter what the relationship will ultimately go nowhere since in the second movie Fishlegs and Snotlout are competing over Ruffnut.
Hiccup, like Aang, not only is a pacifist who prefers peacemaking to violence, not only has a boy just a few years older than him obsessively stalking him, but has an inseparable bond with and rides a flying creature who, by all appearances, is the Last of His Kind. Add in the flight suit he likes using, and it's been unanimously decided that, in another world, Hiccup would definitely be an Airbender.
Even if they didn't have the same voice actress, Heather undergoes almost the same journey in "Have Dragon, Will Travel" that Katara does in "The Southern Raiders" — tracking down the murderer of her parent(s), despite the protests of the hero, only to find when the time comes that she can't kill him. Both also have no problem stealing from/looting pirates.
Dagur is basically a Gender Flipped version of Princess Azula, both being The Caligula with a preference for lightning. His interaction with Alvin in "A View to a Skrill" mirrors Azula's with Long Feng in "Crossroads of Destiny" (the younger villain forms an alliance with the more experienced, older villain, only to successfully double-cross them and take over their army).
Berk and the Earth Kingdom even both have a cabbage merchant who's constantly getting annoyed by the heroes' antics.
Crazy Awesome: Dagur the Deranged. In his second appearance, he takes down Toothless in a sneak attack, and later on weaponizes a Skrill against the Outcasts.
Heather received hate before she even debuted. When it was said that she might "threaten Hiccup's love for Astrid", the shippers went nuts. This became Hilarious in Hindsight once she actually showed up — see Ho Yay for why...
Some shippers are also like this with DagCup, the Dagur and Hiccup ship. Poor Astrid usually loses her Character Development so that the Berserker and Hooligan's relationship can exist.
Draco in Leather Pants: Dagur gets this treatment in fanfiction, usually to justify why he is psychotic and to make him appealing. The fact that he's the youngest villain, not to mention the most competent, wins the crowd quite a bit.
Heather proved to be pretty popular after her first two-parter, enough so to get another one in season three that also begins a character arc, promoting her from Girl of the Week to Honorary True Companion.
Fans quickly became attached to the chicken Tuffnut bonds with in Race to the Edge.
Astrid's zeal in being a dragon slayer in the movie. Just her being a typical Berk Viking and actually being competent at it, right? Now consider how her uncle died and the effect it had on her family's honor and suddenly it takes on a chilling tone. She is unlikely to be the only case like that.
The villagers' excited chanting of "Viking Funeral" since Stoick's in the sequel.
The writing system used in both the movies and series is a real alphabet known as the FUTHARK, commonly referred to as "Runes". The ancient Vikings used it both as a written language and considered each letter to be a powerful magic, which is still used in many occult practices.
In season three, we see what look like strange triangles all over ''The Reaper" and in the projections of the Dragon Eye, this is a writing system known as Cuneiform, considered by many historians to be the oldest form of written language in the world, predating even ancient Egyptian Hieroglyphs
Growing the Beard: While most people agree that season 1 and 2 are far better than any recent series based on an animated movie, Race to the Edge has blown all expectations out of the water with just its first thirteen episodes, with much better writing, CGI effects, and character designs. All in all it seems Netflix has managed to make a decent show into a great show.
Every episode that features Stoick after HTTYD 2, "Crushing It" deserves special mention, when he starts suffering Empty Nest Syndrome.
Everything about Heather when she returns in season three. The biggest probably has to be what she told the Berkians initially about pirates attacking her village and leaving her an orphan, which was a lie. Three years later, her words come back to haunt her when Dagur destroys her village and kills her foster parents.
"A Grim Retreat" becomes even more distressing since the scene with a mind-controlled Toothless about to kill Hiccup happened in HHTYD 2, which led to Stoick's death.
"Stryke Out" has a scene showing the matches from Toothless' point of view, that point of view? Exactly the same as when he was being mind-controlled by the Bewilderbeast to attack Hiccup.
Idiot Plot: Tuffnut spend an entire episode trapped in a net with Barf and Belch nearby all because nobody could think of the most obvious solution to get him out: have one head simply bite or burn the net while the other head is placed under him for him to sit on.
Though to be fair, it was only the Twinsthemselves (besides their dragon) who were in the situation so...
In Season 5, the dragon riders repeatedly mention how "obsessed" Hiccup has become with beating Viggo. The way they talk, you'd think he was turning into Robin after the latter met Slade or Harry Potter in Book 6. Outside of easily falling for a relatively obvious trap of Viggo's, however, Hiccup never acts darker, out of character, or any more "obsessed" with this villain than he has with any others; there's nothing out of character, excessive, or unjustifiable about the level of determination he shows or effort he puts into fighting him.
Ryker is treated like the Dumb Musclebrawn to his Badass Bookworm brother's brains, yet he manages to outsmart Hiccup in both "Night of the Hunters" and "Snow Way Out," both of which also feature him getting the upper hand at some point due to his significant knowledge of dragons. He's actually such an intelligent adversary, it's no wonder Hiccup originally concluded he was the leader of the dragon hunters.
Just Here for Godzilla: Face it, at least a fourth of this show's audience is just watching to see the new dragons.
As of "We Are A Family", Alvin has attained this status after performing a plan that would involve Mildew being betrayed and forced to work with Hiccup, knowing full well Hiccup's overly trusting nature would end up teaching Mildew the training techniques while trying to escape. They think Mildew performed a Heel–Face Turn and Heroic Sacrifice without realizing that he was acting so Alvin can learn the art of dragon taming.
Season 3 also has Viggo, whose first appearance was a two parter that ended in The Bad Guy Wins, pulling a Xanatos Gambit against Hiccup, even when Hiccup began to outwit him.
Mildew crossed it in "Alvin and the Outcasts". Getting the dragons exiled was bad enough, but then he intends to sell Hiccup out to the outcasts. And just to make sure the viewer knows this isn't a "needs of the many" kind of choice, he gloats about it to Astrid.
Alvin himself crosses it by threatening to kill Heather's parents to force her to be The Mole.
It's heavily implied Dagur crossed this a while back by killing his own father. With an axe, no less. And if that doesn't do it for you, the reveal that he killed Heather's foster parents and most of her village certainly will.
Heather herself nearly crosses it by attempting to murder Dagur after saying that they would only capture, but Hiccup revealing that Dagur is her brother stops her. Though it's implied that during the time skip she is willing to use lethal force on Innocent Bystander Vikings while raiding their ships.
Hiccup delivering a line foreshadowing the second film's wing suit directly to the camera in "Gone Gustav Gone," like something out the pre-Growing the Beard Dreamworks films.
"This changes everything." Besides being uttered every time in the opening, when Hiccup first uses the line he had just discovered the dragon eye's projections and couldn't even read the symbols it displayed, making the line feel somewhat nonsensical.
Hiccup shouting at Dagur, "I HATE YOU, YOU HEAR ME?! I HATE YOU!" in "Enemy of my Enemy" like a 5-year-old yelling at their parents.
Non-Indicative Name: "Race To The Edge." There's no urgent need to get to the "Edge," and the "Edge" refers to the Dragon Riders' new home base, the Dragon's Edge, which they spend most of the series based out of. Aside from a few competitions or episodes where they have to stop raiders, there's no urgent, overwhelming need to get there as fast as possible.
One True Threesome: Hiccup and Astrid are the canon Official Couple as well as easily the biggest Fan-Preferred Couple, so its easy to see that no one is getting in the way of that. So when Heather formed a deep bond with both of them, fans were quick to just ship all three together rather than split Hiccstrid.
Mildew has one after suffering a My God, What Have I Done? moment. Subverted when it is revealed he was working with Alvin the whole time.
Heather seems like this after its revealed she only joined Dagur to serve as the mole for the Dragon Riders in Race to the Edge.
Spitelout gets a bit in "Turn and Burn," which explores his insecurity about Stoick's natural leadership abilities and constantly trying to prove himself, and he gets enough development to Know When to Fold 'Em and have enough confidence to start over when his first choice to build an offshore storeroom has to be abandoned.
Though the animation is pretty good, the series tends to stumble in action sequences, particularly dragon breath. By watching episodes like "The Terrible Twos", it's obvious they put extra effort into the fight scene near the end of "Alvin and the Outcasts".
The physics of the show are quite schizophrenic; some episodes use full-on motion capture for the human characters, while others use stiff-looking manual rigging for all motion. Watch an episode such as "Portrait of Hiccup as a Buff Man" with this in mind, and it becomes difficult to take your mind off the blocky and robotic motions of the characters.
An especially jarring thing about the animation is the hair. Hiccup's hair almost always gets a lot of detail, while the other's don't. So you go from a closeup of Hiccup riding Toothless and his hair is moving just like it would in real life, and then you go to a close up of the twins and their hair (which is much longer than Hiccup's) is separated into three chunky blocks that move very unrealistically.
There's a definite upgrade once the show moves onto Netflix, with realistically-moving hair, and more accurate CGI.
Stoick, especially when he chooses to let Thornado go to rescue baby Thunderdrums and take care of them. It takes him another season to admit that he misses Thornado.
Gothi is revealed to be this, given she survived an attack from a Snow Wraith that killed her companions while on a quest to find healing glacial water.
Ugly Cute: Dragons, as usual. Particular mention goes to Meatlug the Gronckle, Fishlegs's placid and spectacularly ugly Gentle Giant of a mount.
Toothless, unlike other dragons, is just cute. And Atrid's Stormfly is beautiful. They share these traits with their riders.
Viewer Gender Confusion: Many viewers keep confusing who is named Ruffnut and who is Tuffnut. For the record, Ruffnut is the female (higher pitched voice and thinner helmet horns), and Tuffnut is the male (deeper voice and thicker helmet horns).
