Pit (SSBB)/Back aerial
Pit thrusts his bow behind him. The move has a sweetspot which deals 15% and insanely high knockback. Back aerial not only deals the most damage out of all of his aerials but also the most knockback out of his entire moveset barring his fully charged smash attacks. The sweetspot is capable of KOing Mario at the center of Final Destination at around 100% and its power is only rivalled by Snake's and Lucario's with max Aura and only surpassed by Zelda's. The downside to his back aerial is the the sweetspot can be difficult to land and the sourspot is infinitely weaker not being able to reliably score KOs until beyond sudden death percents. On the bright side, the sourspot spot is capable of locking opponents up until mid percents. Back aerial overall is one of Pit's best options for KOs as besides its strength, it has decent speed and its landing lag isn't too bad although it can be pretty difficult to land and stale move negation will only make it weaker the more Pit uses it.
