—Brawl manual description

The Assist Trophy (アシストフィギュア, Assist Figure) is an item introduced in Super Smash Bros. Brawl that, when picked up, breaks open and summons a random Nintendo or third-party character to aid the user. Assist Trophies work very similarly to Poké Balls. However, no Pokémon come out of them, and once an Assist Trophy is grabbed, it is automatically activated, assuming the holder is standing on the ground, and not in a jump, attack, or hitstun. Some Assist Trophies must be unlocked in order to be used, such as Isaac from Golden Sun. Unlike the Poké Ball, this item can be eaten by moves such as Kirby and King Dedede's Inhale, and Munchlax.

The majority of Assist Trophies in Brawl are undamageable, with only Starfy and Lakitu being able to be interrupted or otherwise hit or even KO'd. In Super Smash Bros. 4, however, some Assist Trophies can be attacked, potentially interrupting their attacks or otherwise manipulating how they perform and even being able to KO them (this can be seen by their ending animations coming earlier than normal, them having their own death animation, or simply teleporting away). However, there is no reward for KOing an Assist Trophy. In Super Smash Bros. Ultimate, more than one Assist Trophy can be on the stage at once. A larger number of Assist Trophies are also made able to be KO'd, which grants the player who KO'd them one point.

He can produce a flower graphic, and zoom the camera in on the summoner until he leaves.	The Legend of Zelda			?

In addition to the above characters, scrapped Assist Trophy data for Ridley was found when hacking Super Smash Bros. Brawl. In the final game, he was a boss in The Subspace Emissary.

In Super Smash Bros. 4

Assist Trophies return in Super Smash Bros. 4 with a more iridescent design and a softer "popping" sound upon use, instead of the glass-shattering sound effect it had in Brawl. Unlike in Brawl, where all Assist Trophies apart from Starfy and Laiktu could not be damaged nor defeated, several Assist Trophies can now be KO'd, including several returning ones who could not be attacked in Brawl. There are 39 Assist Trophies in total, with 21 new trophies and 18 returning from Brawl. Both the 3DS and Wii U versions include exactly the same Assist Trophies, and unlike in Brawl, there are no unlockable Assist Trophies.

The Assist Trophy trophy in 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. 4

Assist Trophy trophy in Super Smash Bros. for Nintendo 3DS.

Assist Trophy trophy in Super Smash Bros. for 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...

A mystery capsule containing a guest character who'll stand by you in battle. You won't know who's in it till you open it! It could be almost anyone from all sorts of games - a famed warrior or a slightly loopy sidekick! Whoever it is, you can't control them, so you'll just have to trust them.

: Super Smash Bros. Brawl (03/2008)

Trivia

• Hammer Bro. is the only Assist Trophy character to appear as an enemy in the Subspace Emissary.
  • It is also one of five Assist Trophies to appear as an enemy in Smash Run, along with Starman, Lakitu and Spinies (albeit using their 3D designs), Chain Chomp, and Metroid.
• In Brawl's Classic Mode, if the character who summoned an Assist Trophy is KO'd, the Assist Trophy disappears. However, this does not happen in All-Star Mode.
• In the GameCube preview issue of Electronic Gaming Monthly, the Super 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.^{[citation needed]}
• In the Smash Direct for SSB4, Waluigi was shown as a Wario series Assist Trophy, despite never appearing in a Wario game. By the game's release, he is corrected to represent the Mario series, like in Brawl.
• In SSB4, the silhouette figure within the Assist Trophy capsule will occasionally blink its eyes.
• Attendants at the 2007 Whobby Game Festival who played a demo of Brawl claimed to have seen Assist Trophies of Duster from Mother 3, Muddy Mole from Mole Mania, and Rosalina, but the veracity of the claims was never proven, and there is no evidence in the final game that these characters were ever planned.
  • Similarly, attendants of E3 and players of the Smashfest event claimed to have seen Chunky Kong as an Assist Trophy in Super Smash Bros. 4, although he was not seen in any following public demos, and is absent in the 3DS and Wii U version of the game.
• In Brawl, the Mario universe is the only universe to have more than one Assist Trophy.
  • In Super Smash Bros. 4, it is tied with The Legend of Zelda for the most Assist Trophies, with four.
• Jill, Prince Sablé, Ray MK III, Magnus, and Phosphora are the only Assist Trophy characters that have appeared in only one game outside of their Smash appearances.
• The Yoshi and Pokémon series are the only three franchises with playable characters in every installment to lack Assist Trophies.
  • Because the Pokémon series uses Poké Balls instead, the Yoshi series is the only one to lack any assist characters whatsoever.
• Little Mac and Dark Samus are the only Assist Trophies in the series to become playable characters in later installments.
• The Sonic the Hedgehog series is the only third-party series to contain more than one Assist trophy throughout the series, as Shadow the Hedgehog appears in Brawl and Smash 4 while Knuckles the Echidna appears in Ultimate.
