Smash Ball and Final Smash (Super Smash Bros.)

The Smash Ball and Final Smash are an item and a type of Mechanic introduced in Super Smash Bros. Brawl, that allows the user to activate a powerful Final Smash attack when it breaks. Alongside with Assist Trophies, they are considered fan-favorite item/Mechanic 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 Smashes can also feature many iconic/fan-favorite characters to assist playable characters.
 * 5) Beside Smash Ball, players 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 re-spawning in order to performed a Final Smash.

Bad Qualities

 * 1) Some Final Smashes are particularly useless or poorly-made:
 * 2) *Jigglypuff's Final Smash "Puff Up" is pretty useless and uncreative as all it does is make Jigglypuff big and it is only effective on Walk-off stages and/or smaller stages.
 * 3) *Peach and Daisy's Final Smash "Peach/Daisy Blossom" is also pretty bad, it doesn't kill your opponents and instead it just makes them fall asleep while peaches/daisies spawn on the ground which you can eat.
 * 4) *Some Final Smashes for some characters are heavily downgraded from the older final smash in previous games, the worst offenders are Sonic and Link. Their final smashes in Ultimate feel weaker then the ones in the previous games and they're also rather lazy.
 * 5) *Zero Suit Samus' Final Smash "Power Suit Samus" in Brawl is arguably the worst final smash in any Super Smash Bros game, all it does is simply turn Zero Suit Samus into Samus and it barely does any damage to the opponents around you.
 * 6) Some Final Smashes were given to the wrong character (EX:Landmaster to Falco + Wolf, and PK Starstorm to Lucas)

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.
