Dragons are creatures with nearly unlimited life spans. They can survive for long periods of time, and no one has found a dragon that has died of old age. Adolescence 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. Once they hit adolescence, hatchlings change quickly, maturing to their full forms in only 2 years.

Dragons don't communicate with each other verbally, but they will growl to scare off predators and frighten prey. Young dragons will emit an extremely high-pitched squeal when they are frightened. To communicate, they use telepathy with each other and to speak to other creatures.

Bright pink dragons are one of the few all-female breeds of dragons. Their bright colors make them easy to spot during dragon mating season. They are primarily herbivores, but eat meat during mating season when it is brought to them by a mate. Mating seasons occur once every 200 years and can last up to 2 years.

Imra's name used to be Irma, which she never liked because it made her sound like someone's ill-favored aunt. Upon moving out of her parent's cave and into one of her own near the LSH towers, and during the same week discovering the comic 'Legion of Super-Hero Dragons', Irma decided to rename herself Imra after the first pink dragon member of the Legion, Imra Ardeen, AKA Saturn Dragon.

Imra is perfectly happy not to have a name which makes her sound like someone's aunt, even if she does have to put up with the occasional fan-dragon geek making bad 'Saturn's Rings' jokes.
