Meta Knight (SSBB)/Down tilt
Meta Knight thrusts his sword along the ground in front of himself, dealing extremely low knockback that hits opponents towards the ground. It has a 30% chance of tripping the opponent, and when it does so, it can easily follow up into a grab, down smash, SHFFed forward aerial, or Mach Tornado. The move also has very fast startup, and deceptive range, being even longer than Marth's down tilt. It also has very quick interruptibility and can be used to pseudo-crawl, which allows it to chain into itself repeatedly until it trips the opponent, which is when one of the aforementioned followups can be utilized. It can also be used against opponents recovering near the edge to force them back offstage, especially against fastfallers, who it can also gimp and lead into a down aerial followed by a Shuttle Loop stage spike, or a variation of down aerials and up aerials. Overall, a useful move at lower percentages, though at high percentages it always knocks the opponent too far away to follow up reliably.
Interrupting the move by shielding on the earliest possible IASA frame.
