A Crate (箱, Box) is an item that has appeared in every game in the Super Smash Bros. series. Crates are containers which can hold various different items or up to three of the same item. Because Crates are very heavy, a character who has picked up a Crate will not be able to jump or attack at all while holding it. After being picked up, a Crate can be thrown in any regular direction (up, forward, backward, or down). Crates are very similar to Barrels.
Exploding Crates are "dud" Crates that do not contain items and explode when destroyed, delivering strong damage and knockback to players caught in the explosion, even to the player who threw the crate. In all five games, every crate has a one in eight chance of being an exploding crate.
In the original game, a character who has picked up a crate will not be able to move at all (in addition to being unable to jump or attack). However, Donkey Kong exclusively has a special ability allowing him to move and jump freely while holding a Crate.
Characters (other than Donkey Kong) carrying a Crate can now move very slowly while holding it, but cannot walk off ledges; if the control stick is held down, the character and the Crate will both tumble off the ledge and they will drop the Crate. Donkey Kong retains his ability to move freely while holding Crates and other heavy objects.
In this game, Crates have a small random chance of containing an enemy from Adventure Mode, such as a ReDead, Goomba, or an Octorok. When they are thrown at opponents, they can deal 18%-22% damage and have a decent amount of knockback.
Crates, along with Barrels, can now have a different appearance depending on the stage played on. On futuristic stages such as Lylat Cruise, they take on a futuristic appearance. On more fantasy-based stages such as Yoshi's Island, the crates will look like wrapped-up presents. Donkey Kong gains knockback-based super armor when carrying a crate, similar to his forward throw.

Rolling Crates are a new type of Crate that appear in Brawl. These Crates are identified by their tiny, black wheels on the bottom, and can oftentimes go unnoticed. They also always spawn at the same angle, unlike normal crates. If a player hits this Crate without destroying it, it will start sliding in the direction it was hit. Characters hit by the Rolling Crate will take damage and lots of knockback depending on the speed of the Crate, and the Crate normally breaks. Since characters can stand on top of them, players can take a ride on a Rolling Crate when it's been hit.
Crates (including rolling crates) return in Super Smash Bros. 4. The futuristic crate now sports a new design, with the Smash logo on the sides. The present crate has been redesigned as well, with an obvious lid and no horizontal ribbons on the sides.
