Zephyr Haddock was born two years after all the dragons of Berk flew off to live in the Hidden World. Eight years later, as her parents and the other adults in New Berk begin preparing their dragons' favorite fish to remember Toothless and the other dragons around Snoggletog, Zephyr begins building traps around the Haddock residence. She reveals she found Stoick's old journals on dragons in the attic and believes her parents were lying about dragons being friendly. She convinces her younger brother, Nuffink to be wary of dragons as well.
Not wanting their children to have the same fear towards dragons as their ancestors did, Hiccup and Astrid decide to bring back the Snoggletog Pageant and center it around the time the Vikings and dragons made peace. Though Hiccup grew worried about whether it would work as Zephyr continued building more traps and sharpening her stick in the meantime.
During the Pageant, Zephyr appears disinterested for most of it until Gobber accidentally starts burning down the stage. When her father's Mechanical Toothless Puppet goes haywire in the process, she stands with her sharpened stick ready to defend her brother. As the fire is put out, the real Toothless rescues Hiccup from falling off a cliff. Thanks to the smoke covering the stage, Toothless is able to fill in for Hiccup and successfully ends the show by allowing Gobber to peacefully touch him just like he did with Hiccup 16 years prior. Despite her initial hesitance, Zephyr enjoyed the pageant's ending.
As the Vikings applaud, Zephyr goes backstage to check on her father, where she ends up meeting Toothless for the first time. The Night Fury smiles at her upon realizing she's Hiccups daughter before flying off to reunite with his family. Touched by Toothless' kind demeanor, she ultimately changes her opinion on dragons. She tells her parents that she loves dragons and Toothless, and starts playing around like a dragon with her brother. Though her parents are confused when she asks them why they didn't tell her they'd bring the real Toothless (as she was the only one at the pageant who saw Toothless in person), they're glad the pageant convinced her of the bonds Vikings have with the dragons.
When the Haddock family arrives at their home with Gobber, they find a glowing crystal from the Hidden World and the bowl that contained Toothless' favorite fish was empty. They quickly run outside and see Toothless, the Light Fury, and the Night Lights leave New Berk. Astrid thinks that it's their turn to visit the dragons.

|— Hiccup introducing his children to Toothless|
Shortly later, Zephyr and her family sailed close to the caldera entrance of the Hidden World. Soon Toothless, the Light Fury, and their offspring were spotted playing on some rocks at the edge of the waterfall. The Night Fury saw the boat approaching and protectively went to inspect it. This frightened Zephyr and she sought protection behind her mother. She watched cautiously until she sensed Astrid was also frightened, when she retreated behind her mother's back. After Toothless recognized Hiccup, Astrid relaxed and calmly told her children that Hiccup and Toothless are friends and that the dragon wouldn't hurt them. Zephyr was hesitant to come out of hiding and recoiled when Hiccup invited his children to approach the dragon. Hiccup gently pulled Zephyr by the arm toward the dragon, and taught the children how to tame him. Still scared, Zephyr and Nuffink did as their father instructed by reaching their hands toward Toothless. She awkwardly avoided eye contact with the dragon at first, and eventually squeezed her eyes shut. When Toothless made contact with their hands, Zephyr gave a sigh of relief and grinned in amazement at how docile the dragon actually was.
Zephyr then rode on Stormfly with her mother, being held secure from behind by Astrid. She giggled and grinned at the ride, even lifting her arms at one point to show she was no longer fearful. Nuffink rode on Toothless with his father, but eventually Nuffink was playfully tossed to Astrid while Hiccup invited Zephyr to join him on Toothless. She daringly stood up on Stormfly's back, and allowed Hiccup to grab hold of her and pull her up onto Toothless with him. They were joined by the Light Fury and the Night Light hatchlings, as they flew higher and further into the clouds
Zephyr inherited Hiccup's auburn hair color and Astrid's blue eyes. Her hairstyle and clothing also resembles Astrid's from younger years. Her hair is pulled into two banded pigtails under a studded kransen. She wears a sleeveless tunic in a dark bluish grey, a wide red sash, a reddish brown leather skirt with blunt metal studs. Zephyr also wears olive green cloth bracers with fur cuffs on her forearms, sets of leather bands around her biceps, and green beaded shoulder pads. She carries a small green pouch on her belt similar to Astrid's and a small red bag over her shoulder that has a print of a Night Fury's head on it.
In the book, The Art of How to Train Your Dragon: The Hidden World, she is described as having her father's nervous personality, and carrying notebooks around with her like he had. And in the film maker's commentary, she's said to enjoy taking notes and drawing. She's first seen pretending to adjust the sails and then curiously looking into the water, showing imagination and curiosity. She awkwardly avoids eye contact with Toothless showing her understanding that he's an intelligent animal. Compared to her brother, she prefers to observe rather than interact.
|“||It's ok, he's not going to eat your father. See? They're friends! [src]||”|
Astrid and Hiccup are Zephyr's parents. She appears to want to imitate her mother by helping with the sails when we first see her. She trusts Astrid to protect her when she hides behind her, and despite being terrified, is obedient to her father when he has her approach Toothless. She allows Hiccup to take her hand and adjust it so she can train the dragon. Once on a dragon's back, with her mother holding her firmly from behind, Zephyr bravely stands up and throws her arms up in a cheer. When Hiccup tosses Nuffink to Stormfly, Zephyr seems to understand what's coming next without any form of communication from either parent, and gleefully lets Hiccup pull her onto Toothless with him. She rides with a big grin with both patents.
At first, Zephyr was very scared of Toothless because she had never seen a dragon before. At the Snoggletog Pageant, Zephyr ended up being the only person in New Berk to see Toothless during the show, as she met the dragon when she went backstage to check on her father. She was frightened and nervous at first, but eventually witnessed the Night Fury's kind demeanor when he smiled after recognizing her as Hiccup's daughter before flying off. Meeting Toothless in person ultimately changes Zephyr's views on dragons, as she tells her parents that she loves dragons and Toothless after the pageant.
When reuniting with Toothless in the Hidden World, she still showed some fear and hesitance when Toothless boarded their ship and didn't initially recognize Hiccup. After he does and starts playing around with his former rider, Hiccup allows his children to touch Toothless, where they smile and are in shock and awe. Their parents later take them to ride Toothless and Stormfly shortly afterwards.
Zephyr had briefly ridden on Stormfly with her mother, before she switched places with Nuffink and flew on Toothless with Hiccup. Stormfly is gentle with her when Zephyr stands on her back and is pulled off.
Zephyr had briefly seen the Light Fury along with the Night Light hatchlings.
