Meta Knight (SSB4)/Dash attack
Meta Knight does a running kick. For a dash attack, this move has very high speed, and disjointed range, making it his most reliable approach option. It additionally has nearly entirely vertical knockback at the end of the move, having even more follow-ups than his down throw, and can initiate zero-deaths. However, the beginning of the move is still very useful, as it gives the perfect angle for a chain of up aerials into Shuttle Loop. A defining part of his current metagame, this attack leaves the opponent wide open to other moves, setting up combos until mid-percents, and juggles and KO set-ups at high percents.
Due to its good frame data, favorable hitbox, and excellent combo potential, Meta Knight's dash attack is widely regarded as one of the best, if not the best of its kind.
