Clown Kart Dash

Clown Kart Dash is Bowser Jr.'s side special move in Super Smash Bros. for Nintendo 3DS / Wii U. The Junior Clown Car transforms into a kart, revealing a set of wheels and a pair of tailpipes, reminiscent of the Koopa Clown in Mario Kart 7, and speeds ahead to ram into any opponents in his path. Pressing the Control Stick or Circle Pad forward causes the kart to speed up, allowing the attack to deal more damage overall.

After some time, the kart will spin out, which deals more damage to opponents than ramming into them; this can also be forced by holding back on the Control Stick or Circle Pad, or pressing an attack or grab button. Bowser Jr. can also cancel the move by jumping, which can help his recovery to an extent, but doing this uses up his mid-air jump, if he hasn't used it yet. Also, canceling the move prevents Bowser Jr. from using it again until he touches ground.

This move has two customizable variants:

The first one is Koopa Drift, which enables the spin out to deliver multiple weak hits, but its travel speed is slower, it deals less knockback than normal, and the jump height when canceling the move is shorter as well. However, if Bowser Jr. spins out immediately upon starting the move while airborne, he gains a large amount of horizontal distance without affecting his vertical height much, which greatly improves his horizontal recovery.

The second is Grounding Dash, which increases the startup time of the move, but in return, it travels faster than the other Clown Kart Dash variants, and it can bury anyone that it runs into. However, the move can't deal any damage while airborne, and the spin out doesn't deal any damage at all. Additionally, the move is not able to travel as far as the other Clown Kart Dash variants, and the jump height upon canceling the move is quite low, which hurts its recovery potential. During the startup period, this move grants Bowser Jr. super armor.

The Junior Clown Car also engages its kart mode when Bowser Jr.'s down taunt is used.
