Marth (SSBM)/Back aerial
Marth does a bottom to top sword slash behind himself. It deals 9% damage on the base, 10% in the middle, and 13% when tipped. This move has the unusual property of turning Marth around in the air when he uses it, being the only attack in the game to do so along with its clone, Roy's back aerial. In this regard, the move can potentially be used to setup a Ken Combo. It has some combo use, though a forward aerial is preferred in most situations due to sending opponents on a more favourable angle and having less ending lag. The move can also be used to perform a few techniques, such as jumping off the edge and using the back aerial to turn Marth around so he can grab the edge for an edgehog.
