Wii Fit Trainer (SSBU)/Up tilt
Wii Fit Trainer performs the Triangle pose, bending down and stretching an arm straight up. This attack is an excellent antiair due to its large, long-lasting hitboxes and similarly long-lasting intangibility on Wii Fit Trainer's outstretched arm, which creates a very large disjoint that only a select few characters can successfully challenge from above. Up tilt also serves as a reliable combo tool, comboing into itself at low percents and aerials (typically up aerial) at mid and even high percents. With Deep Breathing active, up tilt can sometimes even true combo into up air as a kill confirm. As of Update 8.0.0, up tilt can also true combo into up smash as a kill confirm, although the confirm is very percent and character specific, not to mention Deep Breathing dependent. Aside from up tilt's arm hitboxes, the move also has a smaller sourspot on Wii Fit trainer's butt which sends the opponent away instead of straight up, making it much less useful as a combo starter, although it can still sometimes combo into back aerial at low percents. Up tilt can also be pivot canceled, greatly improving its horizontal coverage. The move's only real weakness is its complete inability to hit short or pancaking characters directly in front of Wii Fit Trainer, although there are many antiair moves in Ultimate that share this issue, such as Falco's up smash. Overall, up tilt is one of Wii Fit Trainer's only moves with notably large and consistent hitboxes, and is one of her most reliable moves as a result.
