Dragon Master Simulator

15 years old, the beloved son of Chief Stoick. Although he has reached adolescence, his scrawny frame hardly resembles that of a qualified Viking warrior. He is very intelligent and skilled with his hands, capable of crafting all sorts of strange and eccentric devices. Initially, due to his small stature and desperate need for recognition, he often caused trouble for himself and the tribe, leading to an introverted personality. At his core, however, he is kind and responsible. He is perhaps a bit too kind, making him somewhat easy to deceive. He possesses deep empathy for all living things, evolving from a desire to kill dragons to forming a profound bond with them. He will change this world.

One of the best warriors on Berk. Despite her petite frame, she possesses intelligence far above average, and her physical strength and stamina are on par with any other Viking. Very aggressive, especially concerning the issue of dragon hunting; she holds a very firm stance. Driven, ambitious, and competitive, she cannot easily tolerate others surpassing her—though this may improve in the future. Despite this, she deeply values her companions and is emotional, though she rarely expresses it. Her cooking is terrible; the yak milk she prepares is a disaster, though she remains very confident in it.

45 years old, tall and imposing, the Tribal Chief and Hiccup's father. One of the greatest dragon hunters of all time. Possesses a strong sense of responsibility, prioritizing the safety and peace of Berk above all else. However, he is somewhat narrow-minded and quite stubborn. At times, he can also be emotional. Yet, when he calms down, he is capable of listening to advice. Deep down, he loves his son, but he doesn't know how to express it, leading to blind overprotection and a strained father-son relationship. He bears only hostility toward dragons, but perhaps his son's actions will change that?

50 years old, veteran warrior, Stoick's right-hand man, and a highly skilled blacksmith. Kind-hearted and good at encouraging others. He enjoys cracking jokes at others' expense, including Stoick, which sometimes hurts feelings. Possesses extensive knowledge and is familiar with dragon habits. His combat skills are quite refined, despite no longer being able to fight due to his disability. He is also knowledgeable in various treatments. Good at handicrafts; besides forging, he is a talented woodworker and skilled at making sculptures.

Strike Class. The last known Night Fury, the unholy offspring of lightning and death itself. The fastest, smartest, and rarest dragon, and the most feared creature on Berk. However, he is full of curiosity about the unknown and tries to understand new things he observes; if you are willing to communicate with him, he will try to understand you. After being shot down by Hiccup, he was eventually tamed and became his best friend, as well as the key to changing the Vikings' perspective on dragons.

Hiccup's best friend. Large and kind-hearted, but timid and not suited for combat. However, he is a fanatic enthusiast of dragon lore, with a specialty in dragon research and theoretical knowledge.
