Final Smash

Final Smash, formerly called a Super Smash or Brawl Move by fans; is a special attack in Super Smash Bros. Brawl and reappears in Super Smash Flash 2. Final Smashes are incredibly powerful in comparison to most other attacks and, if properly executed, they usually have the capacity to KO at least one opponent. Final Smashes performed correctly will give you a great advantage, and may help you catch up to others in the game, or vice versa. To perform a Final Smash, a player must destroy a Smash Ball and then press the special move button. Multiple Smash Balls can't appear in a match at the same time but can reappear after the Final Smash is used.

Types of Final Smashes
While Final Smashes tend to be unique among characters, there are certain categories they can be sorted into.
 * Directional - These Final Smashes launch an attack in a single direction, which may or may not be controlled. This kind of Final Smash has a blind spot, usually behind the attacker, where targets can hide.
 * Final Form - These Final Smashes only affect the user, who can then rampage around and cause damage. Some transformations buff up the character's existing moveset while others use a different set of controls.
 * Focused - These Final Smashes affect nearby opponents in any direction. Targets can avoid the move by getting out of range, so they're most effective in smaller stages.
 * Trapping - These Final Smashes attack a certain area, grab anyone inside said area (or just a single character), and lay down an inescapable beating. They generally have a small initial range, and will fail if there are no targets caught.
 * Semi-Final Form - These Final Smashes involve a character transforming, but you can't control it as you would the character himself.
 * Stage-Wide - These Final Smashes affect the whole stage, leaving no hiding spots. However, they may be less effective on larger stages.
