Bowser (SSBU)/Neutral aerial
An aerial cartwheel. While it is difficult to connect all 4 hits successfully, it is incredibly damaging for an aerial attack, and it can even open up KO confirms on landing, such as into forward aerial, back aerial, and up aerial. This makes it Bowser's best combo starter when landing with it, as even at low percentages it can combo into an up tilt and up smash. It comes out on frame 8. However, the hits after the first don't connect very reliably due to their knockback scaling and the attack has poor range, with the hitboxes for each hit appearing on specific points on Bowser's hands and feet. It also has a noticeable landing lag (15 frames) and cannot auto-cancel in a short hop.
