Hiccup

In the first film, Hiccup's appearance is very similar to his book counterpart. He is rather scrawny compared to the other Vikings, and is only 5’1”. He initially has little physical strength, as he has difficulty lifting a large standard battle axe handed to him by his father. He has bell-shaped auburn hair parting to his right with freckles on his cheeks and dull, green eyes. One of his more unique traits is a small scar on the right side of his chin, which he received as an infant the night Cloudjumper took his mother to the Bewilderbeast’s nest.

In the first film, he is seen wearing a long-sleeve, light-green woolen tunic with brown leather lacing at the neck and arms, a dark brown fur vest that matches his boots and dark greyish-green pants with lacing at the ankle. When he's working in the Blacksmith Shop, he removes his vest in favor of a beige smelting apron. When he rides Toothless, he eventually replaces his vest with a leather flying harness that attaches to Toothless' saddle. Once he begins Dragon Training, he starts to wear a Viking helmet given to him by his father. Following the battle with the Red Death, Hiccup's left leg up to his mid-shin is replaced with a prosthetic, constructed with a spring system and an adapter stirrup for flying with Toothless. This event deepened the connection between Hiccup and Toothless, both of them now have a prosthetic left appendage.

If observed closely, it can be noticed that he's slightly taller in Dragons: Riders of Berk. He's still wearing the same green tunic and pants from the first film, but he's now wearing a suede vest with Nordic designs embossed at the hem and front closure, and a matching suede boot. His hair has grown slightly longer by Dragons: Defenders of Berk showing the passing of time.

In How to Train Your Dragon 2, Hiccup has grown considerably. Once considered the runt, he's now the tallest of the teens at 6'1" and his hair is slightly shorter and somewhat scraggly and unkempt with two small braids behind his right ear. If one notices closely, it can be seen that he has grown stubble on his chin. His eye color has even seemed to brighten along with his confidence. He seems to have gained a stronger build as compared to the first film. His prosthetic is also different, as it is more mechanical than before, making it "a Swiss army knife for prosthesis". Hiccup seems to have improved its ability and function, as he stated he would in the first film.

His outfit now consists of a basic green tunic, tanned leather pants, and leather armor plating along his shoulders and upper chest, along with arm brackets that make him more streamline in the air like Toothless. When flying, he is also seen wearing a matching spiked, masked helmet that protects his face and head. His armor also doubles as a flightsuit that enables him to glide in the air alongside Toothless. He also carries a weapon, a retractable fire blade called Inferno.

In a flashback during the second film, Hiccup is seen as an infant, swaddled in a brown fur wrap with bare arms. His hair is short and tends to stand straight up on top. In Dragonvine, Hiccup takes on a more casual look with a leather jacket in place of his leather armor.

In How to Train Your Dragon: The Hidden World, Hiccup wears his dragon scale armor during raiding missions, and whilst chiefing maintains a less complex outfit of a brown tunic and black leather vest with three buckles on the front. He's also seen again wearing a smelting apron similar to what he wears in the first film.

In a flashback in the third film Hiccup is seen as a 5-year-old, wearing a similar woolen green tunic as he is in the first film but with larger lacings and none at the sleeve openings. Dark brown fuzzy boots are seen on his feet.

Despite his physical shortcomings, Hiccup does his best to succeed as a Viking. He is intelligent and is constantly creating inventions for various uses throughout the first film, including a bola launcher, a dragon's prosthetic tail and saddle, and a riding vest. However, he is much stronger than he appears.

At first, Hiccup is obsessed with proving himself to the rest of his tribe by killing a dragon. He often doesn't think things through and is more determined to gain the recognition of his peers than he is heedful of others' orders, often causing problems for the entire tribe, including himself. Despite this, Hiccup shows great aptitude at being a strategist: he leads his Dragon Fighting classmates into battle, knowing how to use his friends' strengths in the battle against the Red Death. Hiccup also has very good observational skills that come in handy during his time with Toothless and during Dragon Training. For example, he's able to hypothesize that dragons have a natural disdain for eels when his own dragon companion is repulsed by the sight of one and uses this to successfully drive back a Hideous Zippleback later.

He is very protective of Astrid and in the first movie, he has a crush on her. Their feelings mature as they grew up and as the franchise progressed. Among the other teenage Vikings, Hiccup first comes off as awkward, mainly because he's a poor fighter, and rather scrawny for a Viking, prompting mockery from his peers. As he becomes more adept at fighting dragons, however, they start paying more attention to him, and friendships start developing. Despite this, Hiccup remains shy and secretive, preferring to be alone with Toothless. He also tends to be sarcastic with a dry sense of humor that can sometimes put him at odds with the other Vikings in his tribe. It also seems that Hiccup likes to hide his fear with said sarcasm and dry humor.

Due to his shyness, he had a habit of stuttering and stammering when talking to some of the other Vikings, especially Astrid, or when his father is angry at him.

Despite his many virtues and his clear capabilities as a leader, Hiccup is not without his flaws. He is rather prone to letting his insecurities cloud his judgment and affect his actions; in the film, his desperation for the acceptance of his tribe, and his father in particular, cause him to regularly attempt to kill dragons along with the villagers, only to end up doing more harm than good due to his clumsiness. In Dragons: Riders of Berk, his mistaken belief that Stoick still does not accept him causes him to lead the other Vikings on a potentially dangerous treasure hunt to prove himself in "Portrait of Hiccup as a Buff Man". His innate friendliness and tendency to give others the benefit of the doubt cause him to be a little too trusting of strangers, leaving him vulnerable to manipulation and deceit by more dishonest characters, such as Heather and Mildew, on more than one occasion.

In the episode "Thawfest", Hiccup shows a more unlikable, hypercompetitive side to his personality as he begins to score victories over Snotlout. Since Hiccup is unaccustomed to winning anything, he handles it poorly, letting the glory go to his head to the point where he briefly becomes as arrogant and unpleasant as Snotlout. Hiccup is also prone to overconfidence in his ability as a diplomat, which becomes a major catalyst of the second film's storyline; his total belief that he would be able to reason with Drago causes him to run away from Berk to confront the warlord, causing Stoick and Valka, who both witnessed firsthand the true extent of Drago's psychopathy and knew he could not be reasoned with, to chase after him. This indirectly but ultimately leads to Stoick's death at the hands of Drago when he hypnotizes Toothless to demonstrate the superiority of his philosophy over Hiccup's.

In spite of all his flaws, Hiccup is never above admitting when he is wrong and will do his best to make amends with others, showing he has a great deal of humility, and learning from his mistakes.

One extremely notable character trait Hiccup possesses is a deep sense of compassion. As a child, he is seen empathizing with his father over the loss of his mother, and even crying at the thought of an injured bird being killed in order to put it out of its misery. He later spares Toothless, and in doing so, changes the world of Vikings and dragons forever. He was extremely uncomfortable with the thought of having to kill a dragon in the arena in the first film. Hiccup carries this quality into the television series. He shows great sympathy to Snotlout at the end of the Thawfest Games, giving up his own glory and fame for the sake of his friend, though Snotlout showed no gratitude at all. He will almost never allow Toothless to use his full power against foes to prevent killing them. In "What Flies Beneath", he begs Toothless to spare a Whispering Death that had nearly killed both of them just moments earlier. The peak of Hiccup's sympathy is displayed in his releasing Mildew from an Outcast cell. Upon seeing the Outcasts take Mildew's one beloved possession, his sheep, Hiccup clearly displays pity for the old man. Unfortunately, Hiccup is occasionally naive in his sympathy, as Mildew betrayed him yet again right afterward. Still, his kind heartedness has resulted in many victories and accomplished the training of the deadliest dragons in the world. The first character Hiccup would have been willing to kill was Alvin the Treacherous. Originally, Hiccup was more interested in avoiding him, but as Alvin's plots hit closer and closer to everything and everyone Hiccup cares about, Hiccup seems to harden in a difficult resolution. He ordered Toothless to kill Alvin when he was threatening to toss Astrid off of a cliff.

In the finale of Dragons: Riders of Berk, Hiccup and Toothless even charged Alvin in an attempt to kill him after he had captured, threatened, and deeply insulted both of them.

Overall, Hiccup is an intelligent, kind, and likable person who is naturally big-hearted and innocent. After the first film, he and Toothless have become "adrenaline junkies", performing tricks like free-falling. He has also gone from being a shy boy to a confident young man, and "the greatest Dragon Master this world has ever seen" (as Astrid describes him to Drago Bludvist). He has a charitable and kind nature which allows him to see the good in everyone. He has especially been shown to care deeply for Toothless, his parents, Stoick and Valka, Astrid, and later their children Zephyr and Nuffink.
