Jigglypuff is a playable character in the fighting video game, M.U.G.E.N Trilogy. It was confirmed along with the other playable characters who appear in the original Super Smash Bros. game on January 24, 2015. Mika Kanai (Japanese) and Rachael Lillis (English) provide the role for Jigglypuff in this fighting game, using recycled voice clips from various Super Smash Bros. games.
Jigglypuff first appears as one of the 151 species of Pokémon in Pokémon Red and Green (1996), and appears in all subsequent installments. Jigglypuff was highly prominent and popular recurring character in the original Pokémon anime series, known for putting any human or Pokémon to sleep with its irresistible singing. Prior to Generation VI, Jigglypuff was solely a Normal-type Pokémon, but later in Generation VI, the Fairy-type was added to the pre-existing 17 others, and gained it as a secondary type.
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. The Pokédex also categorizes Jigglypuff at #039 as the "Balloon Pokémon".
Jigglypuff's somewhat feminine appearance may lead others to refer to it as "she". Indeed, while there are both male and female Jigglypuff within the Pokémon universe, females are more common than males, with 75% of all Jigglypuff being female. However, per Nintendo's stance on referring to Pokémon with gender neutral pronouns regardless of gender differences, the Jigglypuff in the Super Smash Bros. and M.U.G.E.N series is referred to as "it".
