Alternate Character Interpretation: Spitelout comes across as being ambitious and not having the tribe's best interests in mind for pushing Snotlout as Berk's next chief even after Hiccup's popularity soars just before the beginning of the story. However his pushing Snotlout as the next chief could easily have started over a legitimate concern over the tribe's future. Valka appeared to have died leaving Stoick with one child (Hiccup). Given how the tribe chooses who would be the next chief, the chief having only one child could potentially pose a problem if said child proves to be controversial and isn't able to get a majority of the vote. In order for the tribe to even consider someone that is not the child of the previous chief, a supermajority would be needed but if like 49% is insistent on the chief's only child being the next chief, things could get very messy. To avoid that kind of situation, Spitelout had to make Snotlout appear to be a much more desirable choice than Hiccup and for a while, it looked like Snotlout would end up as the next chief. When the battle against the Green Death happened and Hiccup went from being thought of as the village screw up to being a hero, Spitelout was so used to the idea that Snotlout was going to be the next chief that he couldn't let go of that idea and continued to push Snotlout and it took Harthacnut's failed invasion of Berk to make him realize Snotlout as chief would be a disaster.

Captain Obvious Reveal: By the time Drago made his reveal, most of the readership seemed to have guessed his identity.
Complete Monster: Mildew is worse than his canon counterpart. Banished from his clan in his youth because of his appalling personality, Mildew was only able to avoid being banished from Berk due to his apparent skill in killing dragons. After being identified as someone useful by Alban spies, he is made a Jarl of a village in Alba in exchange for smuggling some of Berk's dragon hatchlings to Alba, quickly earning a reputation of being brutal and harsh. When Mildew heads an expedition to a dragon nest in Iceland, he enslaves the people who live near where the expedition sets up camp, in spite of his heritage of being from a tribe that rescues people from slavery and likely has former slaves in his recent family tree. His private thoughts reveal that shortly after being banished from his clan he tried to burn alive his entire former clan in an attempt to inherit their property and fortune, taking pleasure in their screams, only getting away with it because everybody thought thought it was an accidental fire. Devoid of loyalty to anyone, Mildew is willing to do anything to gain the power and influence he wants over others and to save his own life.
The polycule of Sigurd/Sophia/Gunnar/Heidrun is a bit too big (4 people) to use a Portmanteau Couple Name, so some fans have taken to calling it the Constantinopolycule.
The Scrappy: Wulfhild is seen as this by some, despite how great the author's efforts to keep her likable are, due to how she's an obscure Historical Domain Character that extremely little is known of to the point that some mistake her as an OC and has seemingly infringed on the infamous 'HiccStrid' ship practiced by many people in the HTTYD/Dragons Fandom.
The Woobie: Heather and her adopted parents were enslaved and enthralled. They were brought to King Adalwin who then proceeded to have Heather taught to act as a spy and Sex Slave, being put through Training from Hell under the assumption that she would be given to a brutish viking who would see her as nothing but a sex toy. One could argue the fact that she was given to Fishlegs, a kind-hearted man she would grow to love was even worse, considering if she did not betray him and bring back anything that Adalwin could use to train dragons, he would torture her parents to death. After she decides to come clean to Stoick (after nearly beating Fishlegs half to death when he catches her trying to steal the Book of Dragons), various members of the tribe make her life unbearable to the point where they either try and frame her for crimes or physically assault her, either because she was with Fishlegs or because they thought she was a traitor.
Heather. Dear gods, Heather. If Fishlegs hadn't been hugging her already after the trial, Hiccup might have tried to comfort her himself, just on general principles.
