Paper Dragons are not truly living creatures. They are pieces of parchment enchanted by magic, and as such, are very vulnerable to fire. However, they behave almost like dragons. The only place where their behavior differs is breeding: paper dragons cannot breed.

Lan Fan is a skilled fighter, despite being made of enchanted paper. She considers herself to be the 'bodyguard' of her fellow dragons, and will always shield them from any danger. However, being fiercely protective of her friends means that her hot temper can get in the way of battle, which makes her vulnerable to strong attacks. It is said that magic attracts magic, and that is certainly true for Lan Fan; in battle, many of her opponents attempt to use magic to disable the charm that keeps her paper-form together. Her namesake comes from the Fullmetal Alchemist character of the same name.
