Jigglypuff (SSBM)/Back aerial
Jigglypuff does a spinning kick backwards. It has a surprisingly large hitbox behind Jigglypuff when it first comes out, nearly twice the length of its leg. This move is extremely useful for edgeguarding, and can perform the infamous Wall of Pain on opponents easily and effectively, which can easily KO if performed correctly, especially against characters with poor recoveries such as Falco and Roy. It is overall among Jigglypuff's best moves and is used very commonly by Jigglypuff professionals.
