Isabelle (SSBU)/Up smash
Isabelle blows a whistle, which spawns a stop sign shooting up in front of her. When sweetspotted and without rage, it KOs middleweights from ground level at around 110%, making it quite powerful, while also being fast with a startup of 9 frames. However, due to its most vertical hitboxes with limited horizontal reach, the move is difficult to land, and said lack of horizontal reach limits it ability to effectively punish out of shield despite the fast startup. Because the move's projectile properties bypass hitlag, effectively giving Isabelle more frame advantage on hit, it can also combo into neutral aerial, up aerial, and forward aerial at low percents.
- Up smash's second hit has more knockback scaling (111 → 116).
- The move has less startup (frame 11 → 9), with its total duration reduced as well (FAF 48 → 46).
- It starts charging sooner (frame 8 → 7).
The second hit is tied to the stop sign, and is considered a non-reflectable projectile. This gives it some unusual properties; Isabelle does not experience hitlag from it, it can clang with aerial attacks, and it does not have its damage modified by Isabelle being giant or tiny.
