Astrid Hofferson is a female Viking warrior of Clan Hofferson of the Hooligan Tribe. She is 15 years old in How to Train Your Dragon, Riders and Defenders of Berk, 18 in Dawn of the Dragon Racers, 18 and 19 in Dragons: Race to the Edge, 20 in How To Train Your Dragon 2, 21 in How to Train Your Dragon: The Hidden World and 30 in the epilogue and Homecoming. In the final act of How to Train Your Dragon: The Hidden World, she marries Hiccup and officially becomes Chieftess of the Hooligan Tribe. They eventually have a daughter named Zephyr and then a son named Nuffink. Astrid is an extremely bright, dutiful, and immensely devoted to her cause to be patriotic of the "Viking ways" until dragons became an integral part of Berk. Competitive by nature and highly dedicated, Astrid works hard to achieve her goals. In the first film, she pushed herself to become a better fighter and becomes immensely irritated with the other student’ lack of focus. After bonding closely with Stormfly, Astrid's focus shifts to becoming a masterful Dragon Rider. In the sequel, she is the champion of the dragon races and her determined and strong personality makes her hard to impress. Though Astrid exudes confidence and might, her interaction in "How to Pick Your Dragon" suggests - at least when she was young - that she may privately feel inadequate and under-estimated because of her gender. While describing Stormfly and the Deadly Nadder species, she trips up and inadvertently applies herself into the discussion. Astrid is emotionally driven, and as a warrior, is sworn to protect those she holds dear. In "Fright of Passage", Astrid's innate pride and sense of duty toward her family drove her to face the Flightmare on her own, without any regard to herself. In "Team Astrid", she blames herself for her family's near-death in Dagur the Deranged's attack on Berk despite being fully aware she couldn't have done anything to prevent it. Her guilt and responsibility toward her family probed her to take immediate action. Even as an adult, Astrid is willing to go rogue and defy direct orders to ensure the safety of her loved ones. When younger, she is short-tempered and somewhat of a perfectionist at times, which is especially true before the integration of dragons. Further exacerbated by her emotional personality, this can lead her to act impulsively and irrationally. In the first movie, Astrid was solely focused on training and the war, often isolating herself and ignoring the other teens. When Hiccup began surpassing her, she grew visibly upset. Fueled by jealousy and suspicion, she started to follow him discreetly, eventually leading her to interrogate him in the Cove. Astrid grew more even and level-headed as she matured, though she is still shown to be quite fiery under intense circumstances. She had also become more openly talkative and closer to her fellow riders. Astrid could be prideful and dismissive of people who she thought of as lesser than her, as pointed out by Ruffnut, but she was also able to own up to her mistakes, yet again demonstrating a never-ending will to improve herself. In "Shock and Awe", Astrid pulled a prank on the Twins as payback for Loki Day, showing significant growth in her playful side. She has also proven to be greatly reliable and becomes Hiccup's most loyal supporter. Her methods of encouragement vary but she rarely outright gives him the answer to his problems. Instead, she boosts up his confidence and stands by him as he walks through the solution at his own pace. She has often shown compassion to the rest of her peers and has especially let Heather confide in her on numerous occasions. Although her loyalties are steadfast, in "Snow Way Out", Astrid had to hold back information from Hiccup at Heather's request. She struggled deeply with guilt over it as she had never lied to him before. In "The Longest Day", due to her overtiredness, Astrid suffered from uncontrollable euphoria. She became overly chipper and peppy, almost to the point of insanity, which is the opposite of the way she usually behaves. By the time of How to Train Your Dragon 2, Astrid has adopted an optimistic and relaxed outlook on life. Although slightly cheeky and overconfident at times, she is more emotionally secure. Her sense of adventure and exploration is also apparent, but her ongoing competitiveness and rigid approach to grave situations remain. As an adult, she is generally more spirited and playful and loves to goof around with Hiccup, Stormfly, and Toothless. During the events of How to Train Your Dragon: The Hidden World, Astrid is Hiccup's sole confidant and emotional support. It is even made clear by Valka that she is the only one that can get through to Hiccup. Her relationship with him is even more secure to the point that they are both willing to marry.
