Secret Assist trophy
Hey everyone i just got news that there is secret assist trophies that you can unlock but you have to do a certain thing to unlock them(note:the source that i got this information from is unreliable so i dont know if it is true)
Custom Robo

To unlock: Play 100 matches in brawl or any related modes
This is the Ray Mk III. It’s the same type that appeared in the Nintendo DS title Custom Robo Arena.
When summoned, the Ray Mk III whizzes around in the air, alternately firing off a shower of bullets from the gun on its left hand and peppering the stage with bombs from its right.
Since it’s a toy, the design for Ray Mk III is small and lightweight.
Isaac

To unlock: Play 200 matches in brawl or related modes
Isaac is an adept from the Golden Sun series who commands earth-based Psynergy. He carries a sword on his back but you won’t see him use it here.
Isaac has the ability Move, which has the ability to move objects. This time, that ability has been represented as a massive hand that pushes away anything in its path.
Infantry and Tanks

To unlock: Play 300 matches in brawl or related modes
These famous units from the Advance Wars series have been represented in Smash Bros. as pixel art. Looking at the number of colours used, I’d say these are the units as they appeared in the Game Boy Advance version, perhaps?
Both types of unit spill out onto the battlefield firing tiny projectiles as they wheel about. They may be adorable, but you mustn’t underestimate them.
Barbara

THE BACKGROUND OF THIS PICTURE IS AWESOME
To unlock: Acquire 25 hidden songs
Barbara comes to Smash from the game Daigassou! Band Brothers and Magic Made Fun: Perform Tricks That Will Amaze Your Friends. She’s also made appearances secretly in games like English Training.
When Barbara appears, she starts to wail on her electric guitar, attacking opponents in the area with sonic waves. The attack can cause multiple hits, so run when you see it coming!
Shadow The Hedgehog
(I do not think that this one is real)

To unlock: Unlock Sonic(that i dont think is real)
Shadow The Hedgehog joins the brawl alongside Sonic! Shadow is known as a sort of rival for Sonic.
When summoned, Shadow uses his Chaos Control to slow the speed of those nearby him. Naturally the Chaos Control has no effect on the character who summoned Shadow.
In addition to the Assist Trophies mentioned above, Gray Fox also requires certain conditions to be fulfilled in order to unlock him.
To unlock: Unlock Snake
I suppose it only makes sense that Assist Trophies associated with guest characters appear concurrently with those guest characters, don’t you think?



You cant unlock shadow I beat submiss aquarim and got sonic, but not shadow.
Shadow the Hedgehog is a real assist trophy. I forgot how to unlock him though. I might have to explain how to unlock him tommorow. Anyway, his effect is to slow down time for opponents (sort of like a stopwatch). By the way, it’s Subspace Emissary.
Shadow is suppose to appear after you unlock Sonic. Maybe you did it wrong?
