Smash Ball and Final Smash (Super Smash Bros.)

The Smash Ball and Final Smash are an item and a type of last resort introduced in Super Smash Bros. Brawl, that allows the user to activate a powerful Final Smash attack when it breaks. Alongside with Assist Thophy, it is considered a fan-favorite item for good reason.

Why It Rocks

 * 1) The idea/concept of Smash Ball and Final Smash are incredibly unique.
 * 2) Once you break a Smash Ball, you can use your power attack to activate a Final Smash attack which will do major damage to other players.
 * 3) The special effects on Final Smash are really awesome, which stays true to the original game.
 * 4) Final Smash features many iconic/fan-favourite characters to assist playable characters.
 * 5) Beside Smash Ball, player must first either fill the Final Smash Meter in Super Smash Bros. Ultimate (although then the Final Smash will be weaker), be given the ability by Victini or fall sufficiently far behind in a match that they are given a "Pity Final Smash" upon respawning in order to performed a Final Smash.

Bad Qualities

 * 1) Some Final Smash are particularly useless.

Trivia

 * Many Final Smash trophies credit their origin solely to Brawl in that game, or no credit at all is given in for Wii U, despite many Final Smashes (e.g. Light Arrow, Giga Mac, Wario-Man, Landmaster) being based on abilities from a character's respective series.
 * In fact, the only one not to do so is Super Sonic, which lists Sonic the Hedgehog 2 (the game in which the ability debuted in the Sonic universe) as its other game in Brawl, though it (like the rest of the Final Smash trophies) gives no game of origin in for Wii U.
 * In the Iwata Asks interview for Super Smash Bros. Brawl, Masahiro Sakurai stated that he had intended to add Final Smashes since the first game in the series; in the debug menu of the first game, unused sound bites of characters can be found that were likely meant for these attacks, such as Ness shouting PK Starstorm.
 * In SSB4's and Ultimate's Training mode, the Smash Ball is much weaker, taking around one hit before breaking. In Brawl, it acts as it would normally in a match.
 * Ryu and Ken are the only fighters with two distinct Final Smashes in a single installment. Cloud also received a new Final Smash for his Advent Children costumes in version 10.1.0 in Ultimate, but it is merely an aesthetic change to his default one.
