- For the CPU Mode, see ITEM.
An item is an object that appears on-stage during a match that can be picked up for use 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 Smash Bros. series, but their inherent randomness and inconsistent risk/reward balance results in them being banned from tournament play.
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. Characters can only hold one item at a time. If an item is left alone, it will eventually disappear. 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.
 Types of items
Items can be grouped into several categories based on their effects.
- Container items release other items once broken open, which can be done either by attacking them or by picking up and throwing them. In general, container items have a 12.5% (1 in 8) chance of exploding instead of releasing items.
- Battering items are wielded by characters once picked up, turning their neutral attack, forward tilt, dash attack, and forward smash into an item swipe.
- Shooting items fire projectiles when used, typically replacing the neutral attack and neutral aerial of the user. They all have limited ammunition and will merely shoot blanks once it runs out.
- Throwing items can only be thrown at opponents. Holding a throwing item means that a character cannot use most of their attacks as pressing the attack button will simply throw the item.
- Status items apply some sort of effect to the user, often beneficial but not necessarily. Some status items only need contact to be used (instead of needing to be grabbed).
- Recovery items decrease the damage of the user (or increase their HP in Stamina mode). Starting in Melee, recovery items can be picked up even when the character is already holding an item.
- Collectible items do not affect the match but instead are added to the player's collection once picked up. Computer players will not attempt to pick up collectible items, but if they do so accidentally they will not count.
- Special items do not fit into the above categories.
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.
