Hitboxes

The move can be charged for up to 120 frames, with each charge frame adding 0.085% damage to the hitboxes, for a maximum of 29.115% on the ground and 26.115% in the air (per hit) if released right before reaching full charge. When fully charged, the hitboxes are instead changed directly with no additional damage modifier.

For both versions, landing a fully charged hit produces a Special Zoom.
