An item is an object, that either randomly appears on-stage during a match or is summoned by a character's special move, that can be picked up and used by characters. Many items can be wielded once picked up, while others apply an effect, and almost all can be thrown at opponents. Items are a large part of the gameplay of the Super Smash Bros. series, but problems with randomness and inconsistent risk/reward balance results in tournament rulesets universally requiring that random spawning of items be disabled using the Item Switch before starting the match.
If all recovery items are turned off in Super Smash Bros. Melee, the chance of naturally occurring items like the apples dropped by Whispy Woods on Green Greens and Chansey's eggs recovering health is eliminated; the apples will all be projectiles and the eggs will either be explosives or drop other items. In Super Smash Bros. Brawl the same is true regarding the apples (since Chansey does not appear). Additionally, the vegetables on Summit will not appear if food is turned off.
Items appear from stage-dependent designated locations at various times throughout a match based on the frequency set in the Item Switch. Characters can pick up items by standing near one and pressing the attack button; items can also be grabbed in midair starting in Melee with the grab button, or grabbed during dashes and aerial attacks in Brawl and SSB4. Characters can only hold one item at a time (if Villager's Pocket ability is discounted). If an item is left alone, it will eventually disappear, flashing briefly beforehand (Pitfalls, Green Shells and Ore Clubs being exceptions). Items that are picked up by characters can be dropped or thrown with the grab button, and they may be dropped if the character takes a hard hit. The damage done by a thrown item depends on how fast it's moving. Most items can also be swallowed in Brawl and SSB4, and in the latter, can even heal these characters when they do so, unless the item is an explosive.
In Super Smash Bros. and Super Smash Bros. Melee, the chance of a character dropping their held item when hit is (hitbox damage)/60. In Brawl and Smash 4 this chance is noticeably lower.
Thus, if a hit deals 6% damage, the chance of it causing an item drop on a given frame is 10%. Roy’s fully charged Flare Blade in Melee deals 50 damage, so it has a drop chance of 83.333%.
Types of items
Items can be grouped into several categories based on their effects.
In addition to the above, certain items can be heavy, which limits those that pick them up into walking slowly (or not at all in SSB) and throwing. Only Donkey Kong can move quickly or jump while carrying a heavy item.
