Captain Falcon (SSBM)/Forward aerial
Formally known as the Knee Smash, Captain Falcon sticks out his knee. If it lands during the initial frames, the opponent is electrocuted and suffers extremely high knockback, with the move being difficult to DI out of. If it lands any other time, the move is very weak with little knockback, though it can be chained into another Knee, and it can gimp some recoveries (such as Falco's) in certain situations. Captain Falcon can also SHFFL this move so he can effectively follow up with his other great aerials, including itself. Considered one of the best moves in Melee and the most powerful forward aerial. Can impressively KO as low as 60% off stage.
It can be utilized in many of Captain Falcon's aerial combos, being an excellent combo finisher and versatile part of his combos alike, as well as a generally great KO move and edgeguarder. At low percentages on grounded opponents, the move can also chain into itself. A clean knee can even be followed up with an aerial Falcon Punch in the legendary "Sacred Combo".
