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.

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.

Perci is mild-mannered and polite, succumbing to even the harshest and most unfair orders of others.  Often he would come back to his spot in the cave with some form of injury, insisting he was alright.  His owner kept telling him not to until she finally told him to go with another dragon when exploring the cave and the outside world.  Now Perci travels with Lady Ichigo for his own safety.  She insists she's still in love with Raptoryu.
