Falcon Punch refers to Captain Falcon's neutral B attack. It is one of the most powerful attacks in the game, with the highest knockback of any of Falcon's attack (including charged smashes). It is also very slow, with a start-up time of 52 frames. As with all neutral B attacks, this move can be redirectioned by tapping the analog stick in a direction, returning it to neutral, and pressing B quickly.
Combos into Falcon Punch
Despite the slowness of Falcon Punch, there are a few situations where a launcher (namely, down aerial) can combo into Falcon Punch.
Tapion Punch Combo
Named after Tapion, this two-hit combo leads into Falcon Punch after an l-canceled down aerial. It works on Fox as low as 75% damage, Falco as low as 78%, and C. Falcon as low as 80%. It can be avoided with Directional Influence.
G-Regulate's Falcon Punch Combo
Named after G-Regulate, this combo works similarly to the Tapion Punch Combo, but uses a platform. Captain Falcon must l-cancel a down aerial onto a platform so that it hits an enemy below him. Against some characters at some damages (notably Marth at 65%), Falcon can combo his down aerial into Falcon Punch. It can be avoided with Directional Influence.
