Shimmer-scale Dragons are a very beautiful breed with small—but highly reflective—scales that shimmer and shine as the dragon moves through water. They don’t have fins or webbed feet, but their long, eel-like bodies allow them to swim quite fast. They were once rumored to carry large pearls in their claws—causing many to seek them out in search of this fabulous treasure. In reality, the “pearl” is of greater value to the dragon, for the fabled treasure is actually an egg carried by a migrating female.

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.

Alpha Trion is one of the oldest living dragons in Jazz57's cave, and with that age comes a nuanced understanding of his race and their place within the universe. In his youth, he went by the name A3, and in this time, he helped lead the enslaved dragons in their rebellion against their cruel masters, the humans. In his older years, he has found a comfortable role in serving as adviser to other dragons. Though not taking part in the battles, he is firmly on the side of the good dragons, serving as a mentor and guide, especially to Optimus Prime and Elita One. He is an enigmatic old dragon, though he is known to be the guardian of Vector Sigma and the custodian of its circuit key. His sage-like manner paints him in almost a mystic tone, and possible connections between Alpha Trion, Primus, and the history of dragons itself have boosted him into legendary status.
