Bowser Jr. (SSB4)/Down aerial
The Junior Clown Car extends a drill from its underside hatch to pierce opponents. Its high ending lag is compensated by the hitbox it produces upon landing, which grants it follow-up potential. If the attack hits an opponent, it can cancel quickly into other moves; if not, Bowser Jr. suffers from moderate ending lag. This could be similar to the Spin Drill from Super Mario Galaxy.
