A final smash is a new feature in Super Smash Bros. Brawl. The final smash is character-specific and is incredibly powerful. It is probably the character's strongest move, and each character has a different final smash. These attacks range from Mario's Mario Finale, where he shoots a huge wave of fire from his hands, to Pit's Palutena Army, where he summons flying Centurions to attack his opponents. The only ways to perform a final smash is to grab a smash ball, or through a "Pity Final Smash". The Pity Final Smash is a final smash given to a character when he or she is far behind in points, upon being revived he or she will be in stand-by mode. Multiple Smash Balls can appear in a match, but they are quite rare.
