Meta Knight (SSB4)/Forward aerial
Meta Knight slashes in front of himself three times. It has the longest range of his aerial attacks and hits on frame 9, giving it some utility as a spacing and landing option. At very low percents, it can combo into another forward aerial, or into Shuttle Loop until mid-percents. Its long range, good speed, and decent power make it effective in a Wall of Pain. However, the move has moderate landing lag, fairly high ending lag, and low damage, requiring very precise spacing to avoid being punished, and is also his slowest aerial. Combined with its subpar combo ability, these factors give it overall limited utility, and it is generally thought to be his worst aerial attack.
