Perhaps among the most venerated of dragon breeds is the Zyumorph, a breed whose selfless heroism and strong moral compass are nearly unparalleled by other dragons. Zyumorphs have an innate urge to fend off wrongdoing, and as such, are often sought after in times of peril. Although they are independently quite capable fighters, it is said that their true might is not unlocked until all six Zyumorphs are brought together in times of great duress.

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.

Go go Zyurangers! Go go Zyurangers! Go go Zyurangers! You biome-morphing Zyurangers! It is impossible not to roar this chant whenever the Zyurangers appear. This family of dragon superheroes travels the world in order to stop wrongdoing and injustice. And, they are very enthusiastic about it. Zack is widely considered the muscle of the group. His strong body and intense willpower allow him to stand up to any threat, even those that outmatch him in these aspects. He is quieter compared to the rest of his team, and his intimidating looks often cause strangers to fear him. But Zack is anything but a mean guy. On the contrary, he is very sweet and compassionate and only fights when he has to. He seeks to defend the innocent as well as his team. He is the eldest among them, so takes on a very protective role. Though he is usually on the defensive, if anything happens to his team, Zack will unleash his full, terrifying strength. There is nothing he cannot crush when he is angry.
