The Falcon Kick is Captain Falcon's Down Special Move in Super Smash Bros. Brawl. It is a long ranged kick engulfed in flames that sends Falcon forward. It has decent knockback and damage, but is best used for it's duration and punishing ability.
Falcon Kick will go forward when used on the ground, but will go downwards at an angle if used in mid-air. In Super Smash Bros. Melee, using it in air would restore Falcon's double jump. It has a long duration in the air as well, but it can backfire, as it could send him too far down, which could KO him, or it could stop on the ground, with ending lag.
