Relationships
Hiccup Horrendous Haddock III
In the film, Stoick's biggest problem with his son Hiccup is that he doesn't listen or follow orders. Whenever he talks to Gobber about his parenting troubles, the subject is not about Hiccup's size or lack of strength, but about Hiccup's alarming tendency to ignore orders. However, that is probably untrue, or at least not completely, considering his joy when Hiccup did very well in dragon training and exclamation of how the times his son was considered the worst viking Berk had ever seen were very rough. This happens again in the series when he tells Bucket to draw Hiccup considerably more muscular than he truly is. Since Hiccup is convinced that Stoick is disappointed because of his diminutive size, he goes out of his way to prove himself to his father, and, by extension, to the village, as a Viking. The two are implied to rarely speak to each other themselves when he reveals to Hiccup that they "finally have something to talk about" with Hiccup's new-found "talent" for dragon-fighting. When the two do speak, it's typically one-sided with Stoick doing the talking and Hiccup trying to get a word in edgewise. By the end of the movie, Stoick realizes and apologizes for his neglect of Hiccup's words and is finally proud of his son. In the series, their relationship is much better, now that Stoick finally accepts him and listens to whatever he wants to talk to him about, rather than ignoring him. But in the second film, he pressured Hiccup to become chief and apparently he realized his mistake after Hiccup ran away.
In the end, Stoick's love for his son was strong enough that he sacrificed his own life to save Hiccup from a mind controlled Toothless' plasma blast.
During Stoick's funeral, Valka reveals to a distraught Hiccup that when Hiccup was born, he was born early and weak which made Valka believe he would not survive. But Stoick kept faith and believed that Hiccup would grow and become the greatest Viking Berk had ever seen. Showing that Stoick always loved and had faith in his son.
Wife
Valka: In the film, when Stoick hears of Hiccup's successful performances in Dragon Training, he gives him a Viking helmet forged from half of Valka's breastplate; Stoick's helmet is made from the other half, saying it keeps his wife's memory close, indicating he dearly loved her. After finding her again, it is shown that he had lost Valka in a dragon abduction 20 years prior to the events of the second movie, and had thought she was as beautiful as she is now. They then spend a lot of time together, including dancing.
Valhallarama: Valhallarama is Stoick's wife and Hiccup's mother in the books.
Gobber the Belch
Gobber is a good friend of Stoick's and acts as a bridge between Stoick and his son Hiccup, both nearly polar opposites of the other. Gobber convinces Stoick to allow Hiccup into the dragon training program, reasoning he can't protect him forever - he can only prepare him. When Stoick decides to sacrifice himself to the Red Death to buy the villagers time to escape, Gobber elects to stay with him to the end, further hinting at their strong friendship.
Spitelout
Stoick's younger (possibly half) brother and apparent second-in-command. Stoick seems to trust Spitelout to lead the villagers to safety, though their relationship in the movie is never truly explored. In Thawfest Stoick and Spitelout are shown to be previous rivals, like their sons. Spitelout beat Stoick every year when they competed, as the Jorgensons have never lost the Thawfest Games.
Thornado
Thornado is Stoick's dragon in the series. Stoick begins searching for a dragon for himself, but rejects the known species on the island. That's when he meets a blue Thunderdrum that had been attacking the fishing boats. Stoick is impressed by the dragon's strength and picks him. However, the Thunderdrum is very stubborn and continues to try to escape. Hiccup tries to tell his father that training a dragon is about trust, but Stoick appears not to listen. Thornado manages to escape and Stoick and Hiccup find him near a cave. Stoick intends to fight the dragon, until he sees that he was just helping his injured friend. After helping protect the injured Thunderdrum from a pack of wild boars, Stoick and Thornado bond and become friends. Although they are not always seen together, Stoick cares about Thornado. He is very worried about his dragon when he gets sick like the others. When Thornado recovers, Stoick is very happy. The two have similar personalities, as both are stubborn and strong, but have a soft side when protecting their loved ones. Sadly, Stoick had to set Thornado free so that he could protect and take care of the three baby Thunderdrums in Bing! Bam! Boom!.
Skullcrusher
Skullcrusher is Stoick's new Dragon in the second film, and has been to be very loyal and helpfull towards Stoick, as he helped him his son. However, he isn't as close to Stoick, as he was to Thornado.
