Storm Dragons are the masters of the skies. They are excellent fliers and land only to rest and eat. In addition, they have full control of the weather. They are very hot-tempered and easily angered. They will attack any human that bothers them, conjuring strong winds and dangerous lightning.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Storm Summoner has a very strange personality. He and Storm Singer are always together and they act exactly the same. Sometimes, when a bold dragon comes to the mountain area, it hears about these two dragons that should never be separated, and the bold dragon tries to separate them. Then Storm Singer and Storm Summoner get very angry and cause huge storms to strike the mountain and they're the center of it. The only way to calm them down is for Pupmon to convince Manetrike, being an Electric dragon and unharmed by electrical storms, to get one of the two to chase him and get them into run into each other, then everything back to normal.
