Assist Trophy (Super Smash Bros.)

The Assist Trophy is an item introduced in Super Smash Bros. Brawl that, when picked up, breaks open and summons a random character to aid the user. It is a fan-favorite for good reasons, alongside Smash Ball.

Why It Rocks

 * 1) The concept is cool and very well-executive.
 * 2) Most of the Assists do a proper job in helping + keeping the one who summoned it alive and killing the one who did not summon them/him/her/it.
 * 3) Most of them could also help turn matches that players could lose in into matches they could win.
 * 4) It is also satisfying when the regular player opposed Assist Trophies get Defeated or KO'd.
 * 5) The Item contains many iconic/Fan-Favorite Characters such as Shadow, Tiki, Isaac, and Guile.
 * 6) They could also enhance scores if KO'd or Defeated during result screen when the match is over.
 * 7) You can actually grab Assist Trophy characters in Super Smash Bros. Ultimate.

Bad Qualities

 * 1) Some Assist Trophies are able to somewhat ruin the experience for the player, such as Mr. Resetti (Who does nothing but make speeches when not attacked), the Nintendogs (Who take the entire screen making it difficult to see if the player character's opponents are hit or not), the Devil (Devil World) (who moves not only moves the stage boundaries, but also the blast zone making it easy to get knocked out), and the Skull Kid (who flips the screen upside down or reverses controls).
 * 2) Some are also either annoying or frustrating in bonus Matches. ((EX:The Sheriff in the 9-Volt and 18-Volt Spirit Battle (Who has 100% Pro A.I. meaning it is almost impossible to beat that Spirit Battle especially mostly when using spirits)).
