Peach (SSBM)/Back aerial
Peach bashes her butt backwards. The move has two different hitboxes, with one strong hit, and a weaker hit. The strong hit has good knockback and is a reliable KO option offstage, being very useful for edgeguarding whilst floating. The weak hit is commonly used in aerial combos to position the opponents into moves such as neutral aerials. The move can also be used OoS, though its startup is not as fast as that of Peach's neutral aerial.
