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.

Purple 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.

Mini Iris is quite a beautiful dragon, which is a point which Little Terror uses to bully the purple dragon. However, Angel of Peace has found the sweet and gentle nature of this dragon to be a good change from the disputes he has to sort out.

Mini Iris is usually found with the eggs, checking each one to make sure they are healthy and not diseased.

She is a good mother, shown by her success with her mate Angel of Peace to rear Zeljko.
