Castform (Japanese: ポワルン Powalen) is a Template:Type2 Pokémon whose type can change to Fire, Water, or Ice depending on the current weather.

It is not known to evolve into or from any other Pokémon.

Biology

Physiology

Castform is an artificial Pokémon created by the Weather Institute in Hoenn. It was designed to help scientists predict the weather, and consequently changes its appearance (and type) when the weather changes.

In its natural state, Castform is small, gray and resembles a cloud. When it is extremely sunny, Castform's lower half becomes pure white while the head turns orange with smaller orange balls surrounding it. This gives Castform's head a shape that is similar to the sun. During rain, Castform's lower half becomes a darker shade of gray. The head is blue, resembling a drop of rain. In hail or snowy weather, Castform's head turns purplish-blue. The rest of of the body changes into a mint green cumulonimbus cloud. Strangely, Castform does not have a form for sandstorms or fog.

In all forms, Castform has markings around its eyes similar to a pair of sunglasses.

Gender differences

None.

Special abilities

Castform has the aforementioned ability to change its form with the weather (although it lacks forms for sandstorms and fog). Castform is capable of various Fire-, Water-, Ice-, Electric- and Template:Type2 moves. Castform is one of the few Pokémon that can learn Weather Ball.

Behavior

Trivia

• Castform's weather-based transformations are the same color whether or not it is Template:Shiny2.
• When Castform undergoes a weather-based transformation, the graphical interlude is the same as that of a Pokémon using the move Transform.
• It is the only Pokémon able to learn both Ember and Water Gun, as well as the only Pokémon able to learn both Ember and Powder Snow.
• Castform will not transform in fog, during a sandstorm or in Shadow Sky.
  • However, in Pokémon Mystery Dungeon, fog transforms it into its Rain form.
  • Weather Ball will become a Template:Type2 attack in a sandstorm, despite Castform not having an elemental form for it.
• Castform's Weather Ball will always receive STAB, even when its form is changed, except in a sandstorm, when Shadow Sky is active, or if it loses its ability because of Gastro Acid, Worry Seed, or Skill Swap.
  • Castform is the only Pokémon to receive this benefit from Weather Ball.
• Castform and Cherrim are the only Pokémon to date that change with the weather.
  • They are also the only fully-evolved Pokémon that can change forms freely and are not banned from tournaments.
• In Pokémon Mystery Dungeon: Explorers of Time and Explorers of Darkness, Castform is a body size 4 despite it being a body size 1 in the first Mystery Dungeon games and its in-game sprite still being the same size in the second Mystery Dungeon games. This is probably for game balance reasons.
• Castform's weather-based transformations cannot be viewed in the forms section of the Pokémon Diamond and Pearl or Pokémon Platinum Pokédex, nor do they appear on the field in Pokémon HeartGold and SoulSilver. They do, however, appear in the Pokémon HeartGold and SoulSilver Pokédex forms section.
• Despite several Pokédex entries stating that its molecules are just like water, it is not a Water-type Pokémon, though it does become one in rain. It may also be a reference to the fact that it resembles a living cloud.

Origin

It appears to be intended to resemble and act like a living cloud. Its ability to change shape and type depending on the weather condition makes similar to a weather balloon. It's also similar both in concept and design to a teru teru bozu, a Japanese charm doll used to wish for good weather.

Name origin

Castform's name seems to be a combination of forecast, predict the weather, and transform, referring to its ability to change type depending on the weather. The German and French names refer to this as well.

Powalen may be a combination of 天気予報 tenkyohō, weather forecast, and 変わる kawaru, to change or transform.

In other languages

• German: Formeo - From form.
• French: Morphéo - From morph and météo (weather forecast).
• Korean: 캐스퐁 Caspong
• Chinese (Taiwan): 漂浮泡泡 Piāo Fú Pào Pào - "Floating puff/bubble".
