List of Assist Characters

Default Assist Characters

Name Description
Andross Star Fox Emblem Andross, the main villain from the Star Fox series (his appearance based off his original depiction) appears from the Assist Trophy, and, floating in the background of a stage, will inhale and spit forth a flurry of harmful polygons that damage characters. This is based on his main attack in the original Star Fox.
Devil Super Smash Bros. Emblem
(Demon in Europe)
The devil is from Devil World, a game unreleased in America. When released from the Assist Trophy, he moves the stage outside the screen. The players will only be able to move within the visible screen and will lose a life if they go off the screen at any point.
Dr. Wright Super Smash Bros. Emblem Dr. Wright from Sim City appears and attacks opponents by building large skyscrapers beneath them, sending them flying upwards. The attack is executed right in front of Dr. Wright and the vertical range is very high, so fighters should run away immediately after he is released.
Excitebike Super Smash Bros. Emblem A group of Excitebikers, appearing in their original 8-Bit form, drive across the stage, dragging players along with them, eventually driving off screen with the players caught.
Assist Trophy 4

Helirin Super Smash Bros. Emblem The Helirin from Kuru Kuru Kururin appears as a stage obstacle, rather than an actual assist player. It acts as an additional platform, rotating on its axis and moving, sometimes getting in the way when trying to recover.

Jill & Drill Dozer Super Smash Bros. Emblem Jill from Drill Dozer charges at opponents in her driller.

Little Mac

Lyn Fire Emblem Emblem Lyn enters from Fire Emblem (GBA), the very first Fire Emblem released worldwide. When released, she charges her sword, then disappears, and reappears near an opposing player, slashing them at alarming speeds. Could be considered as a faster version of Samurai Goroh.
Metroid Metroid Emblem A Metroid from the series of the same name will latch onto the nearest opponent, and suck their health away, similar to what they do in the Metroid games.
Mr. Resetti Animal Crossing Emblem Mr. Resetti is a character from the Animal Crossing series. When he is released, he simply stands in one spot, and lectures the players through a speech bubble. Attacking him as he does this will occasionally make him mad and cause an explosion.
Nintendogs Super Smash Bros. Emblem A Nintendog from the game Nintendogs briefly appears on the battleground before blocking the players' views by covering the whole screen causing great distraction.
Saki Amamiya Super Smash Bros. Emblem Saki Amamiya from Sin and Punishment: Successor to the Earth, will appear, and use his Cannon Sword to shoot and slash his opponents. He can jump and shoot as well, and acts as very hard to avoid.
Samurai Goroh F-Zero Emblem Samurai Goroh from the F-Zero series appears and slashes away at the fighters with his katana. This is only limited to a horizontal direction, so fighters should jump on a high platform to avoid him.
Stafy Super Smash Bros. Emblem Stafy, from the Japan-only Densetsu no Stafy series, appears as a vulnerable Assist Trophy. Stafy will perform his spin attack on an opponent if he has the chance. However, fighters can easily attack him and send him flying.
Tingle Legend of Zelda Emblem Tingle simply calls up random effects, such as a barrage of flowers that appear on the stage. These can be helpful (like a rain of hammers) or a hindrance (like a tight close-up of one of the players).
Waluigi Mario Bros. Emblem Waluigi chases after a selected foe, kicks him/her into the ground and finally, he does one final power kick, or hits the player with his racket.
