An Assist Trophy is an item that, when grabbed, summons a character out of various origins to temporarily aid the holder. Assist Trophies function nearly identical to Poké Balls, however, no Pokémon come out of them, and once an Assist Trophy is grabbed, it is automatically activated only if the holder is standing on the ground without any lag of any kind. Some Assist Trophies must be unlocked in order to be used, such as Isaac from Golden Sun. Unlike the Poké Ball, Assist Trophies can be eaten.
In Super Smash Bros. for Nintendo 3DS and Wii U, some Assist Trophies can be 'defeated' by attacking them, which will make them disappear quickly. In Super Smash Bros. Ultimate, some of the Assist Trophies can be KO'ed just like any other fighter by dealing enough damage, which gives the player a point. Hence, most of them can be grabbed by the players and are affected with items, but they can also air-dodge.
Originally, only one Assist Trophy can be used at any given time. The next Assist Trophy will not appear until the data for the character it will release is fully loaded.
In Super Smash Bros. Ultimate this has changed. Multiple assist trophies can be active at the same time, creating unique combinations. Some assist trophies will attack enemy assist trophies in addition to the other fighters.
There's a rule for this: only damageable Assist Trophies can be at the same time with another, with the exception of Ghosts, which can be defeated but cannot be with other Assist Trophies at the same time. Non-damageable Assist Trophies still can only appear one at a time. Some Assist Trophies cannot be summoned at specific stages.
Some Assist Trophies can show unexpectedly as enemies in spirit battles, or are present as mini-bosses in World of Light.

Super Smash Bros. Brawl
A capsule that contains characters who will help you out in battle. You won't know who's in the capsule until you open it. It may be someone everyone knows or someone who's a bit of a mystery. The majority of these characters are invulnerable, so attacking them is not an option. You know what that means, right? RUN!
Super Smash Bros. for Nintendo 3DS and Wii U
This strange capsule contains a guest character who will aid you in your battle. Who will emerge? Grab it to find out! Maybe it'll be a famous character from a popular game, or perhaps a goofy sidekick here to prove his or her worth. Too bad you can't choose who shows up or control them...
- Hammer Bro. is the only Assist Trophy character to appear as an enemy in the Subspace Emissary.
- In Classic Mode, if the character who summoned an assist trophy dies, the assist trophy goes away. However, this does not happen in All-Star mode.
- In the GameCube preview issue of Electronic Gaming Monthly, the Smash Bros Melee article comments that Nintendo originally tried to implement Assist Trophies in Melee. The only trophy concept they gave details on was one that would release the ducks from Duck Hunt to fly around the stage and interfere with the fighters.
- Oddly, they appear in Super Smash Bros. Ultimate despite regular trophies being absent.
