It is not known to evolve into or from any other Pokémon. It can only be obtained by breeding Manaphy or another Phione with Ditto.
Phione is considered by some to be a legendary Pokémon. However, due to the fact that it can breed and multiple individuals can be obtained, its legendary status remains disputed, with contradiction occuring even between official sources.
Phione is the result of breeding Manaphy in the Generation IV games. As a result, it is very similar to Manaphy in body structure. It has a tiny body with a red gem on it. Phione has a single rudimentary foot spike and club-like arms. Phione's head is larger than the rest of its body, and extending from its eyes are two small purple circles. It has a flotation sac on its head with a single, ribbon-like antenna on it.
Phione is a genderless species.
Phione going in the drain
Phione's abilities are similar to Manaphy's, but weaker. Phione is unable to use a number of attacks that Manaphy is able to learn, most notably: Tail Glow, Heart Swap, Hyper Beam, or Giga Impact. Phione are supposedly able to create a dew that cures all ailments. Phione also has the ability to melt its body into water and change its body into a more liquid state similar to Vaporeon.
Like Manaphy, Phione always go back to the spot where they are born.
Phione live in warm seas, especially around the Sinnoh region.

Phione is taller and weighs more than its parent, Manaphy.
Phione can be bred not only from Manaphy, but also from a Phione. However, Phione are unable to produce eggs that will hatch into Manaphy.
There was much debate over whether or not Phione is a legendary Pokémon until Pokémon.com revealed that Phione is indeed legendary. This makes it the legendary with the lowest base stats.
The website initially answered that Phione was not a legendary Pokémon, but it was soon changed.
However, this answer was again overturned by a HeartGold and SoulSilver Versions guidebook published by the same company that runs Pokémon.com, where it was stated that Phione is not a legendary due to its ability to reproduce.
Phione and Nincada are the only Pokémon obtainable by breeding a Pokémon they cannot evolve into (as Shedinja is technically a shed shell).
Phione's name is likely a combination of the final syllable of Manaphy's name with clione, sea angels. Clione are remarkably popular in Japanese documentaries, especially in Hokkaido, on which Sinnoh is based (this may also explain their appearance in Chocovine Town). Also, like clione, Phione's name is pronounced in three syllables.
