Ruffnut Thorston / Biography

How to Train Your Dragon
Joining the same Dragon Training class as Hiccup, at first Ruffnut delights in taunting Hiccup over his poor performance although she doesn't have much success either due to the fact that she couldn't get along with her brother in battle. Later, however, when Hiccup displays an amazing talent for subduing the Dragons, she becomes his avid fan (often pushing and shoving Tuffnut to be the first to talk to him). Ruffnut seems to develop a crush on him and flirts with him (before Astrid pulls her away). Ruffnut decides to join the other teens in helping Hiccup fight the Red Death.

To confront the Red Death, the twins mount the Hideous Zippleback that had been kept at the arena, which fits their fractious relationship, the two naming the dragon Barf and Belch. Each head seems to agree with one of the twins in particular - Ruffnut taking Barf and Tuffnut Belch, and they ride it to great effect in the final battle and afterwards. Notably, they were the only ones not forced from their dragon in the final battle.

Dragons: Riders of Berk
Ruffnut is a Dragon Trainer of the Berk Dragon Training Academy, having joined to help Hiccup train dragons. Ruffnut and her brother experienced a brief falling-out in Twinsanity, when her conflict with Tuffnut reaches the point where they attempt to issue separate orders to each head. They eventually reconciled when Barf and Belch were in trouble, accepting that they would always share their dragon even if they could find other individual interests.

Dragons: Defenders of Berk
In "Zippleback Down', the twin went with the team as they attempted to disable traps that were left over from the time when they killed dragons. While searching for traps, Tuffnut ends up being caught in one. Ruffnut decides to go to Berk and find Hiccup. When she attempts to fly Barf and Belch, they quickly crash land since they need two riders. She decides to go on foot and tells the Zippleback to watch her brother while she was gone. Ruffnut soon sees a forest fire, caused by Barf and Belch, and head back to Tuffnut. She is startled by the Typhoomerang next to her brother, who shows her he trained the dragon. Hiccup then goes to find them, only to be thrown down when Toothless' prosthetic tail was burnt off. With Hiccup's help, they soon realize that Tuffnut's new dragon friend is actually Torch. When the forest fire draws close to the village, Hiccup almost gives up, but the twins figure out a way to keep the fire away from Berk by "fighting fire with fire." Once the fire is out, they returned to Berk, riding on Torch, where he leaves after saying goodbye to Tuffnut. Despite their amazing feat, Tuffnut has yet to have learned a lesson by releasing himself from the trap without help. Despite her efforts, Ruffnut ends up being trapped in the net as well.

A View to a Skrill, Part 1
When a frozen Skrill is brought to Berk, the twins and Snotlout were the prime cause in releasing it. The Dragon Riders set out to find the Skrill, as well as keep the Dagur and the Berserkers form getting it. After splitting up into two groups, the twins attempt to drive out the Skrill by causing a big explosion with Barf's gas and Belch's spark. After saving Hiccup from the Skrill, they're chased by the Skrill ,and Hiccup and Toothless narrowly make it to block the blast of lightning with a plasma blast. The explosion was so great, it knocks the twins out of the sky and away from the group. They land on a seastack and spot Alvin capturing the Skrill. They decide to follow the ship. Meanwhile, their disappearance causes the other Riders to search for them.

A View to a Skrill, Part 2
Hiccup goes to find them and meets up with them on Outcast Island, where they were spying on the Outcasts. Tuffnut goes undercover to find out about the Berserkers' and the Outcasts' apparent truce. He then helps Hiccup to find the Skrill, but it was too late as Dagur managed to get to it first. After Hiccup duels with Dagur, as well as the Skrill (after it's been freed), the twins help seal the hole and encase the Skrill in ice once again. After the chaos had ended, the twins and Hiccup return home to Berk.

Free Scauldy
The Riders find an injured Scauldron on the beach of Changewing Island. Unable to get close, they attempt to leave, but the dragons don't want to give up. Barf and Belch throw their riders off and Ruffnut lands next to the Scauldron. It turns out the fish oil in Ruffnut's hair calms the dragon down. With Hiccup's guidance, Ruffnut bonds with the Scauldron, naming him Scauldy. After a group of Changewing attacks, the Riders move the boulders off Scauldy's wing while Ruffnut distracts him by imitating Hiccup and singing a lullaby that her mother sang to her when she was little. However, Scauldy's wing is broken, thus unable to fly or swim. The gang decides to make a splint for him. The Changewings start heading their way to attack. After gathering the materials, one of the vines they used to act as rope snaps and they are unable to finish the splint. Getting an idea, she takes out her knife from her vest, cutting her hair to use to substitute as extra rope to finish the splint. Ruffnut then is sad to see Scauldy go and tells him to come and visit. Tuff then comments about her looking like a boy now, in which they argue. Scauldy then makes his way to freedom.

In "The Eel Effect", Ruffnut is shown to be slightly smarter than Tuff when she convinced him to slap himself by saying that it would hurt her too (since they're twins). Clearly she just said that because she enjoyed watching Tuffnut hit himself. Later, she and Tuffnut become infected with Eel Pox causing them to propose "science", showing them to not become crazy and rather more intelligent than before.
