Captain Falcon (SSB)/Down aerial
Overview
Captain Falcon does a stomp attack, dealing 14% damage, with a moderately high duration. The move functions as a meteor smash, striking airborne opponents downwards when they are hit by the move. The move's reach is also extended by a small hitbox above Captain Falcon's legs. The move is a powerful meteor smash (even if it hits during the latter frames), and it can KO at moderately low percentages. If the move is used on grounded opponents, it produces very weak knockback that only just lifts them off the ground at 100%. At around 80% it can lead into an up smash to get the opponent into the air, and at around 120-170% it can lead straight into a back aerial or up aerial for a KO.
Captain Falcon can also perform a Ken Combo variation by jumping, using his bair (at lower percentages) or forward aerial (at moderate percentages), jumping again and using a down aerial to meteor smash the opponent. A down aerial can also be used to finish a string of up aerials. According to Ken himself, the Ken Combo was initially developed in Smash 64 using a uair -> dair combo with Captain Falcon.
