Captian Falcon can Falcon Punch as one of his attacks. I believe it's the side special.
However, he sometimes says it when I use his up special, so I am not sure if it's really the up special, or I was just mashing buttons at the time.
How do I use Falcon Punch, and how do I get Captain Falcon to say the line?

How do I Falcon Punch? Super Smash Bros Brawl
Captain Falcon's Falcon Punch is the Neutral Special, documented here.
Falcon Punch is Captain Falcon's Neutral Special Move in the Super Smash Bros. series. The move consists of Captain Falcon throwing a powerful punch, with his fist engulfed in a Falcon-shaped flame.
The Neutral Special Move button is bound by default to the B button, and can be referenced here.
The Neutral Special Move (also commonly referred to as Standard Special Move, Neutral B, or simply B) is a Special Move performed by pressing the special move button without holding a direction on the control stick. Many of these moves are projectiles, which can be used repeatedly to rack up damage indirectly and/or hinder the enemy's approach.
