Hiccup

He is 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.

Hiccup is a very witty, sarcastic boy. He appears very well-spoken but a bit shy at times. Despite the fact that his father is the chief, he is not accepted into his village and is seen as a nuisance, which makes him reserved. He is picked on by his peers for his weak nature, but what he lacks in strength he makes up for in intelligence and kindness. Hiccup has a crush on one of the other teenagers, Astrid Hofferson. He attempts to impress her many times but, much to his disappointment, fails. He also seems to be very good at crafting objects and weapons, which is seen as he works as an apprentice to Gobber, the blacksmith, in his workshop.

Hiccup's strongest trait is his compassion and empathy. He was able to put himself in Toothless' place when he had the knife raised to kill him, and in his own words "I looked at him, and I saw myself". This empathy allowed him to understand and befriend Toothless, and through him other dragons and seeing the creatures beyond their exterior. It is this empathy that changed the world of dragons and Vikings. It ended the war and began the Dragon Training Academy.
