Cloud Flames' primary color is purple. The core is purple, and the rest of the Cloud Flame has a very pale tone of violet, making it one of the most light-colored types of Flame. The Cloud Flame's shape is more oblique and somewhat unstable-looking, randomly flickering and spewing particles similar to how smoke disperses.
Its characteristic, Propagation, carries the ability of increasing and multiplying. As such, it is suited for anything that involves increase of size and multiplication of numbers. It is highly advantageous when performing techniques involving a large area, such as creating a cyclone or an impervious force field. Coincidental or not, a number of Cloud-attribute Box Weapons have the ability to pull out and/or absorb the Flames of an enemy.
