The Smash Ball (スマッシュボール, Smash Ball) is an item in Super Smash Bros. Brawl, Super Smash Bros. 4, and Super Smash Bros. Ultimate. It allows the user to activate a powerful Final Smash attack when it breaks. It only appears in Training Mode, certain Events, standard and Special Smashs, not the main one-player/co-op modes such as The Subspace Emissary.
When a Smash Ball appears, the screen blinks and the crowd gasps, at which point the Smash Ball will begin to roam around the stage freely. To use the Smash Ball, one must first break it by attacking it; any assistants such as Poké Ball Pokémon and Assist Trophies can help break the Smash Ball for the character who summoned them. A 'fresh' Smash Ball can take around 43% damage. When a player successfully breaks one, the screen darkens, and the player whose attack broke the Smash Ball goes into 'standby mode', in which the character's eyes turn yellow and their body begins to glow a rainbow color. In SSB4 and Ultimate, an additional aesthetic occurs where the entire screen fades into a deep grey color and causes everything to look dark except the player with the Final Smash, who glows with the Smash Ball's colors. The Final Smash can then be unleashed at any time by pressing the input for a neutral special move. Players can attack a fighter in standby mode to make them "drop" the Smash Ball, at which point it will begin roaming the stage again. After using a Final Smash, the character is no longer in standby mode and must break another Smash Ball to use a Final Smash again. When the attack ends, the terrain will also go back to its standard colors.
If no one breaks the Smash Ball after a long enough period of time, it flies away and is lost. However, the longer it is flying around, the easier it is to break. It can also be lost if broken by something not attributed to a fighter, including stage hazards (for example, Norfair's lava) and certain items (such as the later parts of a Smart Bomb explosion). Smash Balls are also affected by glancing blows; the Smash Ball will not take damage but will be pushed away. While a character is in standby mode, no Smash Balls will appear until the Final Smash is used (or the Smash Ball is dropped), meaning that only one Final Smash can be used at a time.
The apparent physics of the Smash Ball tend to vary. While it will often bounce off of walls and hard platforms, it will occasionally pass through them. The amount of knockback it takes also varies; sometimes, it will take an attack without even changing its trajectory, and other times an attack will send it halfway across a stage or even outside of the visible boundaries. Like with characters, the camera will be pulled out so the Smash Ball stays visible, so a Smash Ball sent off the screen can pull the camera away from the characters. Smash Balls do not vanish by being forced off the stage; however, it may take a while before it roams back to the stage, and it may wander across the boundary for an extended period of time without returning to the stage and then vanish.
In Super Smash Bros. Ultimate, in addition to the above, there is a 50% chance that a Smash Ball will spawn with physics akin to the Soccer Ball: it will lie flat on the ground unless on a slope, where it will roll down. In this state, if it is not broken in time, the Smash Ball will, instead of floating away from the stage, vanish like a normal item would. If it falls off the stage into the bottom blast zone, it will respawn on the stage. Smash Balls in general are a lot more durable than their appearances in the past two games.
In matches with a Final Smash Meter, Smash Balls can still appear if they are switched on. Breaking one under these circumstances will instantly fill a fighter's meter. However, there is a downside: the Smash Ball can still be knocked out of the player by opponents, and if this happens the meter will empty completely, rather than returning to its previous charge.
The Smash Ball takes the form of a floating Super Smash Bros. logo that cycles through different colors of the rainbow, and is surrounded by an aura of colorful light. In Super Smash Bros. 4, the Smash Ball also leaves a trail of color behind it, and the aura of light is much more intense.
This item is also available as a trophy, with random availability. It is a fairly common trophy to collect.
A mighty item. Each character has a unique secret technique known as a Final Smash that can only be used when that character acquires a Smash Ball. Use it well, and you'll be one huge step closer to victory. It can turn the battle's tide, help you put the finishing touches on a complete thrashing, or even provide a chaotic finish that's sure to leave you laughing until you cry.
