Flystorm was first shown taking a large bone from a green Monstrous Nightmare. When Hiccup and Mildew went through the field of wild dragons, he was the only one to confront them. Hiccup quickly calmed him down by approaching his tail. He then decided to check out Mildew. Hiccup decided to use Flystorm as a way to get into the dragon pit to save Toothless. After Hiccup gave Mildew a quick course in dragon training, the two got on Flystorm and headed off. When they got to the pit, Toothless was already gone and Alvin released the wild dragons he had imprisoned there. With the help of Flystorm, they were able to escape. He also helped the trained dragons from Berk save Hiccup and Toothess. Gobber and Mildew rode him when they tried to escape, but Mildew "fell off" and had to be left behind. Flystorm is now living on Berk.
