Castform<sup>(JPJapanese: ポワルン

Romaji: Powalen)</sup> a species of Pokémon in the series of the same name. It is a Normal type Pokémon introduced in the third generation that can change depending on the current weather. It can turn into a Water type during the rain, Fire type during harsh sunlight and Ice type during the hail.

Physiology and Behavior

Castform is an artificial Pokémon that changes appearance and attitude based on the weather. Its body is made of cells exactly like those of water molecules, causing its cellular structure to be chemically altered by temperature and humidity. Though not of its free will, Castform uses this ability to protect its tiny body. In its Normal Form, it resembles a plain, gray cloud with a single wisp extending from the top of its head.

Regardless of the form it takes, it will always have a large, spherical head and a lighter colored mask-like marking over its eyes. Various experiments were conducted to change its form in artificial conditions, but all have failed. Aside from its various forms, Castform is able to utilize weather powers in the form of its formerly signature move, Weather Ball. Despite its man-made origins, it can be found in grassland areas.

Sunny Form

Under bright sunlight, it takes on its Sunny Form. Its lower half becomes pure white, while the head turns orange has develops small orange spheres around it. This gives it the overall appearance of the sun above a small cloud. Its skin glows and dries, and becomes hot to the touch.

Rain Form

When it is soaked in rain, it takes on its Rain Form. It has a dark gray lower half resembling a storm cloud. The head turns blue and resembles a raindrop. Its body is soft and slippery and seeps with water when compressed.

Snowy Form

When it is hit by hail, it takes on its Snowy Form. Its head turns purplish-blue. The rest of the body changes into the shape of a mint green, cumulonimbus cloud. Its body becomes a smooth ice-like material, partially frozen measuring temperatures near 23 degrees Fahrenheit.
