Wario (SSB4)/Forward aerial
Wario performs a flying kick. It can autocancel in a short hop fast fall, is tied with numerous other characters for the fastest forward air in the game and provides somewhat decent reach with lingering hitbox. It is Wario's main approach option due to these properties, and it is a very versatile attack, being useful for many different purposes.
The speed of the move, both in startup and endlag allow it to combo into itself well, and the late hit can combo into another forward air at high percents or half waft. When forward air starts putting the opponent into tumble, Wario can potentially lock them with dash attack or a late forward air, should they miss their tech. Forward air is also decent for edgeguarding, with the lingering hitbox and combo potential in the air. It is however his weakest aerial by far and severely lacks kill power, hampering its use offstage. The range of the move is also very poor, lacking a hitbox at his toes and in general being a short-ranged move.
Overall, it is a valuable asset for Wario, and serves as a fairly useful tool in his arsenal.
