It wouldn't be a parody of Super Smash Bros. Brawl if I didn't show off some Assist Trophies. However, for this game, I am calling them Assist Characters. Each one has its own powers, whether it be a distraction, boosting characters' stats, or even fighting other players. There are 24 assist characters in total.

Assist Characters
Serenity (Serenity can use support magic that will slowly heal a character who gets hit by her spell.)
Tiger Eye (The screen darkens, as the tiger focuses and then, having teleported, she delivers a double, powerful strike focused on the nearest opponent.)
Boninio & Bonette (The Boninians will shoot five homing rockets from their inventions, powered by Volcano Peppers (4 small & 1 large) at their opponents.)
Evil Jeanie (Evil Jeanie will summon one intense blue flame that moves very slowly. However, any player who touches it will instantly be KO.)
Captain Steelburg (Captain Steelburg will slash his sword while chasing opponents.)
Rebecca (Rebecca scorches opponents with intense flames, alternating between left and right.)
Konoyo (Konoyo will charge his energy, creating powerful gusts of snow that swirl around him, trapping opponents who are within his range.)
Trickzy (Trickzy will home in on an opponent and toss the balls he juggles, which bounce around and push them off the stage.)
Birdgon (Birdgon will fly in front of the field and block the screen. And the duration of how long this creature appears depends on his emotion when he was summoned.)
Tomadacha (Tomadacha will run and jump around, attacking with powerful jabs and uppercuts.)
Firestone (Firestone will randomly perform one of four kinds of attacks: wind, fire, snow, and water.)
Gigabit (Gigabit would fly around the stage, shooting missiles and blue energy bullets.)
Chameleon Kid (Chameleon Kid will run around attacking opponents with his elastic tongue. Also, he can stick to the walls.)
Jet (Jet would be swooping by and striking the stage with lightning bolts.)
Gamer (Gamer will try to cast a magical spell to summon a very rare item on the stage. If attacked, he would mess up the spell that causes an explosion.)
Vic (Vic will take out his pocket watch and swing it back and forth, reversing all players' controls.)
Zara (Zara will produce a massive pillar of fire, trapping opponents within her vertical range.)
Arabi (Arabi shoots a powerful horizontal beam. It has a very high OHKO potential, due to its immense knockback.)
Kimmi (Kimmi wanders around the stage and attacks opponents with her spear. If the opponent is far away, she will throw it, which deals a random element damage.)
Leezord (The Leezord walks around the stage to nibble on players, hurting them. Sadly, it can be knocked off the stage.)
Squeek (Squeek will start playing a handheld game, as the camera zooms in on her, the blast lines are brought closer, so that whoever is left outside the camera will be KO.)
Spimer (Spimer will move around and try to bite players, but will heal the player who summons her on the stage.)
Devlimp (Devlimp will press a button on his belt that produces a reflective sphere around himself that the summoner can use to protect himself from projectile attacks.)
Dazzle Kong (Dazzle Kong delivers a series of jabs to her opponents and finishes with either a smash punch or an uppercut attack. She can one-hit KO if she combos her jab into an uppercut.)
