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.

Black dragons are warriors. They are strong and capable in battles of force, but also ample magic users, capable of devastating opponents with their spells. Their bright eyes give them excellent night vision, which is why they generally hunt during the night.

Eisenhower is proud of his heritage.  His mother is one of the most powerful dragons in the cave.  Red China is a Black dragon, and is therefore quite proficient in physical combat and magic.  Eisenhower was targeted for a short time by Harry Truman, an adversary of his mother.  This ended when Red froze Harry solid for a couple hours, and refused to thaw her out.  Harry had to be thawed out by South Pacific, a resident Magi dragon.

Eisenhower is rather ashamed of having a Mint dragon for a father, but he has grown used to it.  Joe DiMaggio, probably for his lack of a competitive nature, has become quite popular with the female dragons.  Not a bad legacy to live up to.
