Katachi

The Katachi is a type of demon that can take up multiple forms, and uses it's life force for it's more powerful attacks. They start off as cloud-like black puffs, and from early ages on, find themselves skilled in magics and resistant to non-physical forces that are not their own.

Life Cycle
Katachi spend the first 25 or so years of their life unable to reproduce. The next 153 or so is adulthood, in which they can reproduce with anything they can take the form of. The offspring will be a Katachi because the genes mess up and manipulate the other genes until it has forced the other genes to assimilate. The last 22 or so years are spent unable to reproduce, however they gain extra strength and are able to transform into other demons at will.

Transformation
The Katachi is born as a cloud-like puff that has the inherited instinct to imitate something. They like things that move, so it is rare to come across one that decided to become a tree. The thing they imitate must be alive, and they must imitate at least one thing before stage two of their life hits. If they do not have a form by the time stage two rolls around, they die and dissipate. They have no way of thinking other than imitation until they take a form, so many Katachi die before they can learn brain functions from the things they could have taken the forms of.

Once a form is taken from one category, they are unable to replicate and add another. For example, Humans and Ciurus are Creatures. If a Katachi takes the form of a Human, it is no longer eligible to take the form of a Ciurus – the Human becomes it's one and only Creature form.

It takes time after a transformation for a Katachi to transform again, and so it is best for them to think about why they want to be in their form before they take it.

Trivia

 * Males have blue eyes while females have red eyes. It is not known why that's the case.
 * The mental capacities of the forms they take work together no matter which form they are in. They can be a dumb monster but think like a Human just for having a Human form.
