Jigglypuff is currently ranked 36th on the current Super Smash Bros. Brawl tier list in the low tier, which is an extreme drop from 5th in the Melee tier list, due to several factors. The main such factor is its terrible transition to Brawl's physics (like Captain Falcon, Jigglypuff's comboing ability was more reliant on hitstun than other characters), in addition to its nerfed finishers such as Rest, which instead of KOing under 25% like it did in Melee, it doesn't reliably KO until around 75%, and it being much more difficult to land due to Brawl's less hitstun and falling speed (thus preventing Jigglypuff from comboing into it). In addition to this, Jigglypuff has terrible reach in most of its attacks, one of the worst ground games (a combination of poor reach, slow ground speed, and terrible ground attacks), the worst endurance of any character in Brawl (exacerbated by Brawl's defensive play), most of its attacks being punishable on landing at low percents (combination of low base knockback in its attacks and high ending lag), and poor air to ground transitioning due to its floaty falling speed that prevent it from approaching safely in many match-ups. Such factors combine to result in terrible matchups (Including seven hard counters) and tournament results, in spite of its incredible air mobility, effective aerial game, strong edge guarding game, and possessing one of the best recoveries. As a result of its huge nerf in its strongest traits and terrible transitioning to Brawl, Jigglypuff holds the dubious distinction of having the lowest tier drop.
 How to unlock
The player must complete one of the following requirements to unlock Jigglypuff:
For all three options, the player must face Jigglypuff in a brawl on Pokémon Stadium 2.
Jigglypuff is the lightest, slowest, and floatiest character in the game. Its fighting style is unique as it will spend most of its time in midair, as it is designed to be the ultimate midair brawler. With 6 jumps, combined with the second fastest air speed (only second to Yoshi), the slowest falling speed, and Rising Pound, Jigglypuff dominates in aerial combat, and with its forward aerial and back aerial moves, it allows for it to use the Wall of Pain technique very effectively allowing opponents to be KOed at low percentages by being juggled off-screen. Jigglypuff's excellent aerial maneuverability make up for its slow dash speed (the slowest in the game). A main disadvantage is that Jigglypuff's lightweight and floatiness means that it is sent flying rather easily in any direction. However, its light weight (combined with being floaty and small) also makes it immune to most chaingrabs. Although it is immune to most chaingrabs, its air release sends almost no horizontal distance at all (though it's high vertically and can move one frame before anyone else's air release) allowing grab release combos by Yoshi.
Jigglypuff has many attacks with decent knockback, but these attacks also have very low range (being light and poor ranged makes approaches very dangerous) and sometimes a medium amount of starting and/or ending lag. Its recovery is aided by Rollout, also a devastating approach attack on the ground, and the fact it never enters a helpless state makes the attack effective in the air too. However, Rollout, as with all charging approach attacks, can be predictable and could lead to a self-destruct, if not careful. The move Rest provides invincibility frames which come out in one frame - faster than a shield - this allows for avoiding some dangerous situations. Rest can also deal up to 45% damage, and has vertical knockback and almost no horizontal knockback, guaranteeing a KO at around 75%, meaning Jigglypuff's vulnerability time after Rest is avoided if the attack hits. However, Rest leaves Jigglypuff extremely vulnerable if it misses. Jigglypuff also has a good array of Smash Moves, though they are quite laggy, though strong nonetheless. Jigglypuff lacks projectiles, but its great aerial mobility helps it dodge many of them easily. Upon breaking its shield, Jigglypuff will be sent for a Star KO if there is no ceiling above it (see Shield Jump).
Jigglypuff is a character of extremes, having the slowest falling rate, the second-fastest air speed, the lightest weight, the shortest height of jumps, and the slowest dash speed. This makes playing against it different from playing against any other character.
As mentioned before, Jigglypuff suffered a large nerf. Jigglypuff's rest special move has significantly less knockback and initial damage (it can no longer KO at almost any damage percent), but adds a flower on the opponent's head instead of having a fiery effect, which can make much more damage in total than in Melee. Jigglypuff's forward and down aerials are stronger, but its back, neutral and up aerials were weakened between games and its down aerial can no longer be used for edgeguarding. Jigglypuff's forward throw is much weaker (no longer KO around 130%). Forward smash is weaker and its smashes are slower and have longer ending lag. Rollout now has two stages of being "fully charged": 'Fully Charged' and 'Super Charged'. Rollout also no longer puts Jigglypuff into a helpless state if used in the air. Jigglypuff has greater air control now due to having faster midair acceleration (although it's now second to Yoshi) and slower falling speed (which makes its midair jumps give more distance). Jigglypuff is no longer tied with Zelda for having the slowest dash speed (due to Zelda's dash speed increasing). On the upside, it is heavier than it was in Melee (although it is now the lightest character). One minor change is that Jigglypuff's pound now has strictly vertical knockback (as opposed to it previously knocking the opponent up and behind Jigglypuff). Another minor change is that Jigglypuff's down throw now only does damage when the opponent is thrown, not during the rolling part of the attack.
Jigglypuff also received some cosmetic changes. The biggest cosmetic change is that almost all of Jigglypuff's movements now make a squeaky, rubbery, and puffy sound (including midair jumps and attacks). Another cosmetic change is yellow sound waves appear around Jigglypuff when sing is used instead of colorful sound waves. Jigglypuff also doesn't open its eyes in the last part of the song, instead only opening them when the song is over. Jigglypuff's blue and green costumes have changed. Blue is now a sunhat, and green is now a nightcap. Jigglypuff also has a new costume which is a white hat with a bit of pink, based on the female trainer's hat from FireRed and LeafGreen.

 Tier placement and history
Jigglypuff has always been seen as one of the worst characters in Brawl; right away players noticed her significant nerfs to key attributes, and her terrible transitioning into Brawl's physics and gameplay changes. And over the years, despite Jigglypuff's still strong aerial game, air camping abilities, and amazing recovery, metagame developments for Jigglypuff have been startlingly barren. Jigglypuff is also perhaps the most unpopular character in Brawl competitive play, lacking the dedicated playerbase other low tier characters have, having barely any notable players, and being a very rare sight at even local tournies full of casual players. As such, Jigglypuff has always been ranked among the four worst characters in the game in all iterations of the BBR's tier list. Some players even think Jigglypuff is the worst character in the game and not Ganondorf; in fact the Japanese rank Jigglypuff as the worst character on their tier list.
 Role in The Subspace Emissary
To unlock it, first the player must complete the Subspace Emissary, whereupon an extra door in The Swamp can be found that links to Pokémon Stadium 2, where Jigglypuff is performing a song. Jigglypuff is then fought and, if defeated, is unlocked (if not already unlocked) and joins the player's party.
 Exclusive stickers
These stickers can only be used by Jigglypuff or a select few including it.
 Trophy description
A Balloon Pokémon. It invites opponents in close with its big, round eyes, then puts them to sleep with a calming song. The secret to the song's unfailing efficacy is Jigglypuff's ability to sing on the wavelength that will make its opponent the sleepiest. It also uses Attract to infatuate opponents who touch it. It uses a Moon Stone to evolve into Wigglytuff.
