Hitboxes

The hitboxes with the "shield breaker" effect have a damage multiplier of 1.15×. However, they can only strike opponents' head hurtboxes, and unlike the move's damage increase by charging, this multiplier functions as a "damage taken" modifier (like the 1v1 multiplier), so it has no effect on knockback dealt or damage to shields.

The move triggers a Special Zoom if it breaks a shield with any of the hitboxes.

Not fully charged

The hitboxes' damage can be multiplied by up to 2.2× depending on the move's charge, for a maximum of 18.53% right before reaching full charge. More specifically, the damage multiplier is equal to 1 + 1.2 * (charge frames / 60). When fully charged, the hitboxes are instead changed directly with no additional damage modifier.

Differences for Kirby's Copy Ability

• All hitboxes are placed lower (Y offset: 8.5u/7.5u → 5u (angled forward), 8.5u-12.5u/14u-14.6u/9.8u-12.3u/13u-14.7u → 6.5u-10u/11.5u-12u/9u-10.5u/11u-12.5u (angled up), 6.5u-4u/3u-2.7u/5.6u-3.5u/3u-1.7u → 4.5u-1.5u/-0.5u-(-1u)/2u-0.5u/0u-(-1.5u) (angled down)), better matching Kirby's dimensions.

Timing

On frame 12, the aerial version adds forward momentum of 0.5 (in units per frame) if not fully charged, and 2 if fully charged.

Charges between	11-12
Clean hit	19
Late hit	20
Interruptible (from release)	51 (40)
Animation length (from release)	62 (51)

Differences for Kirby's Copy Ability

• The move has a shorter animation (62 frames → 55), allowing Kirby to fast fall, grab ledges, and activate a held Assist Trophy earlier after using it.
