Biography
As revealed in Underworld, many years before the events of the comic, the Rouge Submaripper attacked a ship carying both Captian Fiske and his second-in command, Stoick. It killed half of Fiske's crew and ripped off one of his arms and one of his legs. It would have killed Fiske as well if Stoick hadn't saved him. Fiske wanted to hunt for the dragon, but Stoick refused for fear of losing more lives. Fiske, knowing that he had lost Stoick's support, left Berk to hunt the dragon for himself. He was never successful.

Many years later, Stoick, Gobber, and a crew of Vikings were sailing in the Veil of Mists when the same Submaripper attacked again. After throwing itself onto the boat and nearly destroying it, the dragon wrapped Stoick with its tail and tried to drag him to the bottom of the sea. Fortunatly, Stoick was able to stab the Submaripper in the tail, forcing it to let him go.

When Stoick and Gobber later returned to the Veil of Mists, where they encountered the same Submaripper again. This time, it attacked out of revenge for its earlier defeats, with Stoick being its specific target. Fortunatly, Astrid and Stormfly were able to distract it and get it to chase them. The two led the Submaripper into the Caves of Jotunn, where Fiske had captured the rest of the Dragon Riders earlier. The Submaripper, too angry in its chase to see where it was going, crashed into the cave roof, causing both it and Fiske to be trapped in the cave. Its fate remains unknown.
