Final Smash

The Final Smash is a special move that is possible through the aid of a Smash Ball in Super Smash Bros. Brawl, Super Smash Bros. for Nintendo 3DS / Wii U, and Super Smash Bros. Ultimate. After breaking open one of these items, its power flows into the fighter, charging him or her up. The fighter will begin to emit a yellow aura, and their eyes will turn yellow as well. The character will activate their Final Smash the next time the player uses their standard special move. However, if the fighter does not initiate the Final Smash soon enough, they can drop the Smash Ball if they get attacked enough times.

The games also have a function known as a Pity Final Smash (called Easy Final Smash in Super Smash Bros. for Nintendo 3DS / Wii U). If a fighter is KO'd while being five points or stocks behind the leading player, the fighter respawns with an Easy Final Smash. An Easy Final Smash serves the same functions as a normal Final Smash, but it has the advantage of not having a Smash Ball form, and therefore cannot be taken away by other fighters. Easy Final Smashes also return in Super Smash Bros. for Nintendo 3DS / Wii U, but CPU players will not receive one even if the conditions are met.

The Final Smashes in Super Smash Bros. Ultimate are much quicker and require little to no control, so players can return to fighting quickly. As a result, many fighters that had controllable/transformative Final Smashes received new, instant, and non-transformative Final Smashes (e.g. Super Dragon being replaced by Stampede!, and Konga Beat being replaced by Jungle Rush), although some retain their transformation effect (e.g. Giga Bowser Punch) or can still be affected by user input (e.g. Octopus and Super Sonic can be controlled vertically); while Final Smashes such as Shadow Mario Paint and Grand Star have been made less powerful. This game also introduces the FS Meter, where players can charge up a Final Smash with a meter under the damage meter. The Final Smashes released from these are much weaker, easier to dodge, and can be shielded against. When the player activates a Final Smash, a cut-in of the summoner's face briefly appears on-screen.

History
Most Final Smashes are based on the character's individual background in their series, like Zelda's and Sheik's Light Arrow. However, some have been invented specially for Super Smash Bros. Brawl, like Mario's Mario Finale. Although they were planned to be included in the original Super Smash Bros. (an unused voice sample of Ness's announcing "PK Starstorm" can be found in the files), Final Smashes made their first appearance in Super Smash Bros. Brawl. Masahiro Sakurai compared the Final Smash as a more powerful, "majestic" Hammer item (found in all Super Smash Bros. games), as all players rush to collect it, and the ones who didn't flee after it has been collected.
