Appearance
In the Film, Hiccup's appearance is slightly different from the books. In the film, he's rather scrawny for his age compared to the other Vikings, especially since he has little physical strength as he's barely able to lift a large hammer, and isn't very tall, just being barely around Astrid's height. He has light brown hair parting to his right with minor freckles on his cheeks. If you look closely, you'll notice he has a small, white scar just below his bottom lip, and above his jawline (which he got from when he was a baby, the night Cloudjumper took his mother away). He's usually seen wearing a long-sleeve, light-green tunic and a dark brown fur vest that matches with his boots. When he rides Toothless, he takes off his vest and wears a flying vest to help him stay on Toothless. After Dragon Training, he starts to wear a Viking helmet given to him by his father as shown inGift of the Night Fury. Following the battle with the Red Death, Hiccup's left leg up to his shin is replaced with a prosthetic made by Gobber with a metal foot and spring, which is accessible for flying with Toothless.
If you look closely, you'll notice that his hair has grown mildly between Riders of Berk and Defenders of Berk
In How to Train Your Dragon 2, Hiccup has noticeably grown considerably. He's now the tallest of the teens at 6'1" and his hair is somewhat scraggy and unkempt with two small braids behind his right ear. He seems to have gained a leaner, stronger build as compared to the first movie and is no longer considered a runt. His prosthetic is also different, as it's more mechanical and designed than before, making it like "a Swiss army knife for prosthesis", as Hiccup seems to have improved its ability (as he stated he would in the first movie). His outfit now is partly leather around his upper body with what appears to be a type of armor along with arm brackets that seem to all be designed by himself, making him look more like Toothless. When flying with Toothless now, he's also seen wearing a spiked masked when he glides in the air, as his outfit doubles as a squirrel jacket capable of gliding. His pants are dark brown and has straps around them with a leather boot for his right foot. He also seems to carry a weapon, a fire blade called Inferno.
