Super Smash Bros. Brawl/Assist Trophies

Assist Trophies are listed here and like Poké Balls will release something to help you. Note that Kirbys final smash will cook even anyone that is a Assist Trophy.

Andross
Andross, from the original Star Fox, will appear, move back behind the action, and begin firing polygonal panels at the combatants.

Devil
From the game Devil World of NES (never released in USA) comes the Devil. He will choose a direction and point, forcing the screen to scroll in the same direction.

Dr. Wright
This character from the SNES version of SimCity blows away your enemies with skyscrapers that appear from the ground.

Excitebike
Many motocross racers from Excitebike in their original pixel art come out to rush over your enemies.

Hammer Bro
The Hammer Bro, originally from Super Mario Bros. will chuck hammers at opposing players.

Helirin
Helirin comes from Kuru Kuru Kururin. It becomes part of the stage when you use it.

Jeff
Jeff from Earthbound uses a Multi-Bottle Rocket 5, a device that launches four mini-rockets and one mega-rocket.

Jill
Jill from the Drill Dozer game uses her drill to drill your opponents. Like Piplup, Jill might knock the foes down off from the stage.

Kat & Ana
The Katana twins from WarioWare, Inc.: Mega Microgame$! come slicing your opponents while making a dance in perfect symmetry.

Knuckle Joe
Straight out of the Kirby universe, Knuckle Joe comes out with a devastating Vulcan Jab and will end with either a Smash Punch which shoots straight through the enemies or a Rising Break which is a super powerful punch straight up.

Lakitu and Spinies
Lakitu from Super Mario Bros. comes over its cloud tossing Spinies one at a time. They are in pixel art. Though the down side of this assist that the opponent can kill Lakitu.

Little Mac
Little Mac comes from Punch Out!!. He is small in size, but strong in heart. Don't take him too lightly because he dashes, throws 2 powerful jabs and finishes with an uppercut that will surely take a lot of damage.

Lyn
Lyndis from Fire Emblem crouches and waits, then vanishes before unleashing a powerful strike at a foe.

Metroid
The creature which inspired the title of the Metroid series holds an enemy's head and start draining their health but can be shaken off.

Mr. Resetti
Mr. Resetti from Animal Crossing burrows up from underground and lectures the players. He will impersonate anyone and make fun of them, but mostly the player who is losing. Not the most useful Assist Trophy, but probably one of the most hilarious. He does respond if you hit him, and may eventually release an explosion if messed with enough.

Nintendogs
First appearing in the E3 2006 video (long before Assist Trophies were actually revealed), a Labrador puppy from Nintendogs jumps up and blocks the screen.

Saki Amamiya
He comes from Sin and Punishment: Successor of the Earth, with his Cannon Sword ready to slice and shoot against your enemies.

Samurai Goroh
Samurai Goroh, from F-Zero, will slash his sword wildly while chasing after opponents.

Stafy
Stafy comes from the game Densetsu No Stafy (Japan-only). He shines bright and does a spin attack. This is a weak Assist Trophy because you can easily attack him, and end his time on-screen early. His attack is also weak and is easily avoided.

Tingle
Originally appearing in The Legend of Zelda: Majora's Mask. He "decorates" the stage with all sorts of effects at random including inducing the Curry effect on players.

Waluigi
Waluigi, who first appears in Mario Tennis, chases any foe and stomps them to bury them in the ground, then he keeps stomping to finish with a powerful kick or a hit with his racket.
