The '''Assist Trophy''' ({{ja|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 Ball]]s. 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 [[Gray Fox]] from ''Metal Gear''. 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|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. When the Assist Trophy is close to becoming KO'd, the player who summoned it can KO it to prevent other players from gaining a point.

| align="left" |[[Yuri Kozukata]]

| Yuri busts out her Camera Obscura, a specialized camera to take photographs of spirits, and uses it to take pictures of the battle. This will stun opponents and poison them, leaving them vulnerable to attacks.

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 assists and 18 returning from ''Brawl'', but with 9 assists cut 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.

For the first time in the series, multiple Assist Trophies can appear at once. Players are rewarded points in [[Time]] battles when KOing a defeatable Assist Trophy. Occasionally, opposing Assist Trophies may fight each other. They can also now be affected by status effects such as freezing. Assist Trophies also respawn if they fall off the stage accidentally. The item itself reuses the rainbow dome from ''SSB4''. There are 59 Assist Trophies available in the game, with 27 new assists and 32 returning from ''Smash 4'' (Including 2 assists who were in ''Brawl'' but not ''Smash 4''), but with 9 assists cut from ''Smash 4''.

''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!''

:{{Flag|North America}} ''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...''

:{{Flag|Europe}} ''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.''

{{Trophy games|console1=Wii|game1=Super Smash Bros. Brawl (03/2008)|console2=WiiU|game2=Super Smash Bros. for Wii U}}

*[[Little Mac]], [[Dark Samus]] and [[Isabelle]] are the only Assist Trophies in the series to become playable characters in later installments.

*[[Isaac]] and [[Gray Fox]] are the only Assist Trophies to skip an installment in the franchise and return in a later game. Ironically, both were treated as "newcomer" Assist Trophies on the ''Ultimate'' website.

*Gray Fox is the only Assist Trophy in ''Brawl'' cut in ''Smash 4'' to be from a universe with a playable character (as ''Animal Crossing'' did not have a playable character in ''Brawl'').

*Andross, Devil, Dr. Wright, Hammer Bro., Jeff, Knuckle Joe, Lyn, Metroid, Nintendog, Samurai Goroh, Shadow, Starfy, and Waluigi are the only Assist Trophies to appear in more than two games since their introduction in ''Brawl''.

**Likewise, Infantry and Tanks, Kat & Ana, Lakitu and Spinies, Saki Amamiya, and Tingle are the only Assist Trophies that have appeared in two installments, but absent in ''Ultimate''.

*The {{uv|Yoshi}} and {{uv|Pokémon}} series are the only two franchises with playable characters in every installment to lack Assist Trophies. Other series that share this distinction but debuted later are {{uv|Ice Climber}}, {{uv|Game & Watch}}, {{uv|R.O.B.}}, {{uv|Wii Fit}}, {{uv|Punch-Out!!}}, {{uv|Mii}}, {{uv|Duck Hunt}} and {{uv|Final Fantasy}}.

**Because the ''Pokémon'' series uses [[Poké Ball]]s instead, the ''Yoshi'' series is the only one to lack any assist characters whatsoever.

**{{uv|Final Fantasy}} is the only third-party universe to not have an Assist Trophy.

*{{uv|Dillon's Rolling Western}} is the only Assist Trophy-only universe introduced in ''[[Super Smash Bros. 4]]'' to have solely been developed by a second-party developer (being Vanpool).

**However, {{uv|Kaeru no Tame ni Kane wa Naru}}, while primarily developed by Nintendo R&D1, was co-developed by [[Intelligent Systems]].

*[[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 {{b|Starman|EarthBound}}, [[Lakitu and Spinies]] (albeit using their 3D designs), [[Chain Chomp]], and {{b|Metroid|creature}}.

*In ''Brawl'', the {{uv|Mario}} universe is the only universe to have more than one Assist Trophy.

**In ''Super Smash Bros. 4'', it is tied with {{uv|The Legend of Zelda}} for the most Assist Trophies, with four.

*[[Prince Sablé]], [[Sukapon]], [[Jill]], [[Ray Mk III]], [[Yuri Kozukata]], [[Magnus]], and [[Phosphora]] are the only Assist Trophy characters that have appeared in only one game outside of their ''Smash'' appearances.

*[[Shovel Knight]] is the first and (as of ''Ultimate'') only Assist Trophy from an Indie game developer.

*[[Shadow the Hedgehog]] is the only Assist Trophy to have his voice actor change between ''Brawl'' and ''Smash 4.''

*The {{uv|Mega Man}} franchise has the most Assist Trophies out of any third party franchise, at 3, with [[Elec Man]] appearing in ''Smash 4'', and [[Zero]] and [[Wily Capsule]] appearing in ''Ultimate''.

*The {{uv|Animal Crossing}} franchise is the only franchise to have a different Assist Trophy in each game, with [[Mr. Resetti]] appearing in ''Brawl'', [[Isabelle]] appearing in ''Smash 4'', and Kapp'n appearing in ''Ultimate.''

*In ''Brawl'''s {{SSBB|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]].

*[[Magnus]] and [[Elec Man]] are the only Assist Trophies to have appeared only in ''[[Super Smash Bros. 4]]'' and not have come back in ''Ultimate'', excluding the assists-turned-playable [[Isabelle]] and [[Dark Samus]].

*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 {{uv|Duck Hunt}} to fly around the stage and interfere with the fighters.[https://www.youtube.com/watch?v=mW4lhbnQIII (at 5:40)]

*Attendants at the 2007 [http://www.whobby.com/ Whobby Game Festival] who played a demo of ''Brawl'' [[List of rumors#Assist trophy rumors|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 [[List of rumors#Chunky Kong Assist Trophy|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.

*Prior to the ''Ultimate'' [[List_of_updates_(SSBU)/2.0.0_changelog|2.0.0 Update]], If two {{SSBU|Isabelle}}s used [[Fishing Rod]] to grab onto an Assist Trophy, one would grab on, and the other would not; however, the result would be the former [https://www.youtube.com/watch?v=lJgJZ-BpJOU infinitely spawning the same Assist Trophy] until she got hit.

*Not counting [[Rathalos]], who is fought as a boss, [[Rodin]], [[Black Knight]], [[Samurai Goroh]], [[Phosphora]], [[Thwomp]], [[Spring Man]], [[Starfy]], and [[Moon]] are the only Assist Trophy characters not to appear as Assist Trophy enemies in [[Spirit]] battles.

**[[Knuckles]] can't be summoned in [[Green Hill Zone]] due to being a background character in that stage.

**[[Kapp'n]] can't be summoned in [[Smashville]], [[Town and City]], or [[Tortimer Island]] due to being a background character in these stages.

**[[Moon]] can't be summoned in [[Great Bay]] due to appearing as a background character in that stage. It also can't appear in any large, flat, transforming, or indoor stage.

**[[Andross]] can't be summoned in certain stages most likely due to conflicts with certain stage backgrounds.
