Captain Falcon (SSB)/Down tilt
From SmashWiki, the Super Smash Bros. wiki
Captain Falcon's down tilt is an edgeguarding move. It hits just below him on the first 2 frames, covering the ledge. Its first hitbox comes out on frame 8, its last hitbox comes out on frame 15, and it cools down for the next 15 frames. it has a good interruptibility frame, lessening the 1/4 second cool down time. The tilt's entire hitbox is slightly disjointed.
