Fox (SSB4)/Up smash
Fox's up smash is named Flip Kick and involves him performing a bicycle kick. For how quickly it starts, it has very high power, KOing most opponents at 100%, even when uncharged. Additionally, Fox's legs are intangible up until the late hit begins. The late hit has much weaker kill power than the early hit. Fox has also two reliable set-ups to this move: the late hit of a neutral aerial or the landing hit of a down aerial. However, the move has 45 frames of ending lag, making it extremely punishable if it misses.
