Bowser Jr. (SSBU)/Neutral special
This move is called Clown Cannon that haves the Junior Clown Car opening its mouth and fires a cannonball. It can be charged to increase the cannonball's speed and power. At the end of its path, the cannonball will drop to the ground, which can hit opponents attempting to recover if it is spaced properly. However, it has high overall lag. As the projectile's hitbox changes once it begins to drop to the ground, a cannonball can hit an opponent's shield twice with correct timing, which deals immense shield damage. 10% when uncharged, 7% when uncharged and hits late, 20% when fully charged, and 14% when fully charged and hits late.
Update 3.1.0 has less startup and ending lag overall in midair, allowing to react quickly.
