Pink Dragons are primarily herbivores and only eat meat during the mating season, when mates will exchange kills. When it is not breeding season, pink dragons spend most of their time incubating eggs and caring for their clan’s young. Due to their feminine color, it was traditionally thought that pink dragons were a strictly female breed, but this is not true.

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.

Akuma is a regular little demon: the other dragons have nick-named her "Puck", "Trickster", or "Little Pest". Aku loves to wind others up and doesn't care much for rules. Her favourite past time is to bring other dragons into awkward or embarassing situations, racing against Skywings and Whiptails, and betting. She often dares others into some contest and the stakes are usually something along the lines of "If I beat you in this race, you have to walk around with a bird's nest on your head for one week, and you aren't allowed to explain to anydragon why you are doing it."

Since Aku loses as many bets as she wins, every one has given up on asking her for an explanation, if they spot her covered in green paint, only flying backwards, or only communicating through sockpuppets for a while.
