Toothless appears to be the only exception until he too begins to rebel, but the riders discover to be the true cause to be freshwater-dwelling parasitic dragons called Grimoras. DreamWorks Dragons: Race to the Edge is set about three years after the second season of the DreamWorks Dragons and tells the action-laden story of what happens before the events of How to Train Your Dragon 2. Sullivan Jack Thomas February 16, 2018 2018-02-16 In order to complete the Dragon Eye and discover the location of the King of Dragons, Johann needs more lenses while Hiccup still needs gemstones to complete his Dragon Eye 2. Sullivan John Tellegen February 16, 2018 2018-02-16 After learning his ancestors were dragon hunters who killed off the Dramillions, Fishlegs sets out to Dramillion Island with Astrid against Hiccups wishes to find and help protect the Dramillions from harm. Noting that this dragon is an undocumented species, he takes it in for care and closer study.
Astrid is separated from Hiccup in a snowstorm and finds Heather camped out on a nearby cliff. Hiccup and the dragon riders, thanks to Johann, band back together and track him down to a fog bank beyond their borders and discover a huge graveyard of ships filled with treasures that Dagur would use to build a new armada. After the Armorwing appears, Hiccup notices a Dragon Eye lens on its back. He later double-crosses Dagur returning the Dragon Eye to Hiccup and saving both of them in the process. The riders, Heather in particular, refuse to listen and head in anyway, leaving Dagur to take charge and sacrifice himself to allow the riders to escape. It is up to Hiccup and his friends to convince him otherwise. Sullivan John Tellegen June 26, 2015 2015-06-26 Hiccup manages to rescue Heather, and though she is still determined to take revenge, Hiccup persuades her to leave it for another day.
To make things worse, the ingredients needed to cure the illness are in Toothless' satchel and all but Fishlegs are caught sick. Many recruits apply, including Gustav, Gothi, and Spitelout, but Hiccup takes notice of her overly harsh regimen and points out she wants her students to fail so she has a reason to stay on Berk and protect her family. Jones Jack Thomas June 24, 2016 2016-06-24 With Dagur's information and a map of the location stolen by Johann, the riders send Snotlout and Gobber undercover with Berk's reluctantly lent gold to the hunters' latest dragon auction to rescue the dragons and cripple Viggo's business. Though Hiccup feels guilty for driving Viggo to make such a move, Stoick expresses confidence that he and the others will always be able to stop him. The Riders finally reclaim the Edge, but Astrid discovers Viggo is still alive and has recovered the Dragon Eye, but Hiccup is prepared as his new Dragon Eye is nearing completion. Dagur captures him and Fanghook, whereby Gustav appears to become a part of their crew claiming he knows how to get Dagur the Dragon Eye. Back on the island Astrid and Tuffnut manage to fend off the hunters' attacks and Heather keeps them from approaching on foot.
Jones Jack Thomas June 24, 2016 2016-06-24 Hiccup and the riders are preparing an attack on a hunter shipyard when Dagur appears, asking for Hiccup's help to find Heather. Fishlegs, on the other hand, eats all the berries. Hiccup allows himself to stand trial and face their punishments, seeing Mala and her tribe as potential allies in their struggles against the hunters and eventually wins her trust. After the group traps the leader dragon they realise how much danger the rest of the dragons are in when Changewings begin attacking them. He is rescued by the A team but is left in a state as a result of his injuries.
At the same time, Gobber appears and warns Hiccup of an unpleasant change in Stoick back on Berk that is currently driving everyone crazy. Later, an injured Heather and Windshear return from Vanaheim with dire news. This causes Toothless to come down with the dragons' version of Eel Pox, skittish and uncontrollable fire power. Just as they are about to celebrate his graduation, Savage and a faction of Berserkers start a revolt and imprison Dagur and the dragons. Snotlout uses the Smothering Smokebreaths to get it back and the riders help the Armorwing when they pick apart its hide, earning its trust. When the riders find out they make it clear to him that he is too immature to become a rider, Gustav runs from the island in the night.
Stoick and Astrid try to convince Hiccup that the Singetails must also be treated as the enemy and potentially sacrificed for their victory, but Hiccup remains firm on their innocence and is left lost while the rest of Berk prepares for war. In the end, the twins, who have been pranking everyone without end, receive retribution by the rest of the riders. Ruffnut tries everything from having Snotlout bitten by other dragons and reasoning with him as he is about to fall off a cliff, and Hiccup and Fishlegs reveal the Lycanwing legend was invented to protect a pair of Dragon Eye lenses hidden on another island, but Tuffnut is only convinced when Snotlout appears and states he was actually bitten by a wolf, which bites him as well. The three trust the Fire Terrors to take the Eruptodon egg and it safely reaches the nesting ground where it is bathed in the lava. Hiccup is determined to finally best Snotlout, who constantly gloats about being the reigning Thawfest champion, but Hiccup's successes begin to make him arrogant and boastful, much to Astrid's displeasure and disappointment. They learn the tribe is guarded by a lava-eating dragon, the Eruptodon, whom Mala and the others label 'The Great Protector,' but Hiccup soon realizes when the Eruptodon is captured that Viggo was using them as a distraction.
Hiccup reluctantly allows Mildew to help him find Toothless and escape Outcast Island, a final test for Mildew's loyalty to Berk. Upon landing there, they find the island has been taken over by a massive new dragon called the Catastrophic Quaken. After hearing this, Astrid starts to think that Hiccup isn't interested in her anymore since they are not as publicly affectionate as Dagur and Mala and begins to question her relationship with him. Seeing their fortification, they decide to return with reinforcements, but Garff flies in to help the Deathsong upon hearing its cries, resulting in his capture. Just as Hiccup is left without any ideas on what to do, who to trust, or even how to handle his developing feelings for Astrid in the midst of growing danger, Viggo returns and offers the Dragon Eye as proof of his word and offers an equal alliance to bring Ryker down.
When Ryker reveals there is no prize, Hiccup manages to escape while the riders arrive and defeat the hunters. Hiccup reconciles with Fishlegs and assures him that he would not ever hesitate to leave him in charge in the future. However, the dragon is abandoned in the waters and Hiccup's team rescues it and brings it to Queen Mala for recuperation. When Astrid runs out of ideas, it's Tuffnut's tricks that manage to give them the advantage while Ruffnut escapes on Windshear. In order to guarantee a peaceful coexistence in the future, Hiccups father Stoick Nolan North founded the so-called Dragon Academy, where humans and dragons should get to know each other.
