Editing Assist Trophy

|image = [[File:AssistTrophyWiiU.png|200px|Assist Trophy]]

|caption = The Assist Trophy as it appears in ''Super Smash Bros. 4''.

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 can summon it can KO it to prevent other players from gaining a point.

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''.

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 majority of these characters are invulnerable, so attacking them is not an option. You know what that means, right? RUN!''

AssistTrophyTrophyWiiU.png|The "Assist Trophy" trophy in ''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.

*The {{uv|Yoshi}} and {{uv|Pokémon}} series are the only two franchises with playable characters in every installment to lack Assist Trophies.

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

*{{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]], [[Magnus]], and [[Phosphora]] are the only Assist Trophy characters that have appeared in only one game outside of their Smash appearances.

*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]].

*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.

*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.{{fact}}

*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 [[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.

*[[Dillon]] is the only Assist Trophy to receive an aesthetic change in his appearance between installments, as in ''SSB4'' he was based off of his appearance in ''Dillon's Rolling Western'' and its sequel, while in ''Ultimate'', he is based off of his ''Dillon's Dead-Heat Breakers'' appearance.

*[[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.

*Andross, Devil, Dr. Wright, Hammer Bro., Jeff, Knuckle Joe, Lyn, Metroid, Nintendog, Samurai Goroh, Shadow, Starfy, and Waluigi are the only 13 Assist Trophies to appear in more than two games since their introduction in ''Brawl''.
