Jigglypuff, known in Japan as Purin (プリン, Purin), is a fictional creature in the Pokémon series and a playable character in all four Smash games.
It holds the distinction of being the only unlockable character in all iterations of Super Smash Bros.. Traditionally, it was the first unlockable character in the first two games (Super Smash Bros and Super Smash Bros. Melee). Super Smash Bros. Brawl, however, made it the last veteran character and third last character to be unlocked by VS matches while Super Smash Bros. 4 made it the very last character to be unlocked in terms of VS matches needing completion (though, like most other unlockable characters in the game, it can actually still be unlocked first).
Jigglypuff first appears as one of the 151 species of Pokémon in Pokémon Red and Green, and appears in all versions following it. Despite not being a lead character in the Pokémon franchise, Jigglypuff was selected to appear in the Super Smash Bros. series due to its similarities to Kirby, which allowed the staff to reuse the model and many animations as a base for Jigglypuff. It was also desirable because of its prominent appearance in the Pokémon anime at the time (as well as Mewtwo and Meowth, who were apparently intented to appear in the original game), as a certain Jigglypuff is notable for putting any human or Pokémon that doesn't resist to sleep and has became a recurring character of the anime series since its debut until the end of the original series. Prior to Generation VI, Jigglypuff was a sole Normal type Pokémon, but has later gained the Generation VI introduced Fairy type as its secondary type.
As mentioned above, Jigglypuff is similar to Kirby in appearance, however Jigglypuff have larger eyes, thinner limbs, and large, triangular ears, as well as a curled tuft of hair on on its head. This somewhat feminine appearance has led to many smashers and others who have not played Pokémon to refer to Jigglypuff as a "she". Within the Pokémon world, there are both male and female Jigglypuff, and females are more common than males, but the Smash character is always referred to as "it".
The Pokédex provides additional biological info about the Jigglypuff species: After it mesmerizes its foe with its large, round eyes, it sings its lullaby until the foe sleeps, and does not stop to breathe until the foe is fully asleep; it can perform longer with its single breath if it inflates its body with air beforehand. Its vocal chords can freely adjust the wavelength of its voice, and it sings at precisely the right wavelength to make its foes most drowsy. The sound waves of its singing voice match the brain waves of someone in a deep sleep. Nothing can avoid falling asleep after hearing a Jigglypuff's song, but some are more naturally resistant to the effects than others and take much longer to sleep. This effectively endangers a singing Jigglypuff's life because it cannot breathe.
As a playable character
Jigglypuff is one of the four secret characters in Super Smash Bros. and is considered to be the easiest one to unlock. Its Rest attack is considered to be one of the most powerful moves in the game. Aside from sharing similar physical characteristics with Kirby, it has a slightly better jump than Kirby. Jigglypuff is two-thirds of the way on the tier list, being ranked 8 out of 12.
As a playable character
Jigglypuff returns in Super Smash Bros. Melee as one of the eleven secret characters. It is unlockable after clearing Classic or Adventure with any character, except Mario (unless Dr. Mario is unlocked already). Thanks to an update, and like a few other characters, it has a new neutral special move, Rollout, which replaces its previous standard special move, Pound, which has become its side special move. Jigglypuff has been largely buffed from Smash 64 to Melee, and is now ranked 5th on the tier list in S tier.
Jigglypuff has three trophies in its name, just like all the other playable characters; the original trophy, the Smash Red trophy, and the Smash Blue trophy. Its original trophy reads as follows:
As a playable character
Jigglypuff returns once again in Brawl. Jigglypuff appears the same as before, but is more difficult to unlock than in previous instalments of the series, considering it was the 33rd character introduced on the DOJO!! and the last veteran character to be introduced.
Jigglypuff ranks 36th out of 38 (in F tier) on the current tier list, an extreme nerf from Melee. Jigglypuff suffered from the biggest tier drop from Melee to Brawl, going from top tier (middle-high tier when Brawl was released) in Melee to bottom tier in Brawl.
Jigglypuff is once again an unlockable playable character. It has been buffed from Brawl and its appearance is now more similar to its appearance in recent 3D Pokemon games.
