Nebula Dragons are nocturnal creatures. With the best eyesight to be found, they are often seen staring into space. Each dragon tends to observe a particular nebula and will eventually change their colors and patterns to match it. As the nebula changes over time, the dragon changes with it. The more intricate the design of the nebula, the better chance an individual has of attracting a mate. It is said that the markings on no two Nebula Dragons will be exactly the same.

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.

Starscream is a treacherous Dragon and one of the deadliest. He is also a big coward. He's famous not only for his incredible skill, but also for his limitless (and troublesome) ambition. Starscream believes that he is more suited for command than the evil dragon leader Megatron. Thankfully for Megatron, Starscream's mutinous, power-grabbing plots are almost always transparent, and he can never muster up enough patience to complete a grandiose power play. Even on the few times he has taken control of the evil dragons, he quickly loses control of a situation, but is too arrogant to realize when he's in over his head. He never learns from his mistakes. The only reason Megatron doesn't turn Starscream into slag is due to the fact Starscream is very good at his job of commanding. Despite his constant failures, Starscream believes it is only a matter of time before he prevails, his destiny is inevitable.
