Mii Brawler (SSBU)/Up tilt
Mii Brawler puts their entire body into a lengthy uppercut, sweeping the area directly in front of and above them. Up tilt acts as a general combo tool for Brawler at mid-percents and a niche kill confirm move at higher percents. Around 20% to 50% on most characters, the move can be comboed into and out of using a wealth of moves including their neutral and up aerials, leading to very damaging strings that give the opponent little time - if any - to escape. At higher percents, up tilt can be used to lead into Helicopter Kick or Thrust Uppercut, moves that kill reliably near the ledge and near the upper blast zone respectively, leading to potentially early KOs.
In addition, up tilt hits remarkably low, letting it connect with some fighters' ledge hanging animations.
