Jigglypuff (SSB4)/Up aerial
Jigglypuff sweeps its hand overhead, hitting opponents with 9% damage and decent knockback. The move has limited usage due to two major flaws; firstly, it is Jigglypuff's laggiest aerial, being the aerial with the second longest duration, after down air. However, unlike down air, it is not a multihit move, giving it more ending lag overall, which makes using the move for juggling somewhat difficult. Secondly, it has the least range out of all of Jigglypuff's aerials, having only a small hitbox on its hand which barely reaches above Jigglypuff at all, severely limiting its usage.
However, it does have some use. One benefit of the move is its long hitbox duration, somewhat mitigating the moves laggyness, and making it easier to use the move to prevent opponents from landing. It also has reasonably low landing lag, further improving this ability. It also does posses some degree of KO potential, particularly if Jigglypuff has rage, although it is generally reserved as a last resort kill option, due to its somewhat lacklustre knockback scaling. Furthermore, while it does have a lack of vertical reach, it possesses surprising reach around Jigglypuff, due to the sweeping motion it makes with its hand while using the attack. Finally, when used shortly before landing, it can combo into a standing Rest at very low percents and a jumping Rest at percents higher than this; the former does a large amount of damage without KOing due to Rest's flower effect, and the latter can KO. Up Aerial can also combo into Up Tilt and all Jigglypuff's aerials, depending on the opponent's percent, when used this way.
