Isabelle (SSBU)/Down aerial

Hitbox visualization showing Isabelle's down aerial.

Overview

Isabelle's Down aerial is her primary means of attacking beneath her. The sweet spot possesses a smaller hit box in the center that that changes the landed hit into a spike if connected. The hit box lingers, improving her ability to circle camp and sometimes allowing her to land more safely on platforms.

Despite being visually similar to her Up aerial, this move has different properties that make it deceptively inconsistent. If the smaller 'spike' hit box within the sweet spot is not landed, the attack will send the opponent downwards or towards the side at differing angles, depending on how the hit boxes connect. This makes any possible follow ups largely improvised and based upon how the opponent reacts, even at higher levels of play. Down aerial's longer startup, the spike hit box being challenging to land, and not providing any realistic combo opportunities make it less useful than its counterpart. Nevertheless, it still plays an important role in Isabelle's kit, and can net her early KO's in the right situation.

Unlike Isabelle's other aerial attacks, it has virtually no use in her combos and strings. Lloid Trap can combo into her Down aerial via footstool, but is mostly an impractical novelty since the setup is very situational, difficult, and is likely never an ideal follow up. For the combo to be setup, Isabelle must be right next to the opponent and fully actionable as the trap is set off- in which case, all of her other potential follow ups are also available. When done correctly, the Down aerial hit will send the opponent into a Tech scenario. As this always gives up a clear desirable outcome, and often higher damage output, it is not worth the additional effort and risk.
