False character

False characters are enemies in featured in the Subspace Emissary on Super Smash Bros. Brawl. They are the result of trophies being infested with Shadow Bugs. They can also be created if the bug has memory of the character.

False Bowser
False Bowser makes his first appearence without warning at The Lake. After Fox and Diddy defeat him he dissolves. It is believed that Bowser ordered his fleet of Shadow bugs to copy him and serve as somewhat of a decoy.

False Diddy Kong
When Fox and Diddy were walking by The Swamp, they were ambushed by Bowser. Diddy was then shot by Bowser with the Dark Cannon turning Diddy into a trophy. Bowser then orders Shadow Bugs to "consume" Diddy's trophy. Once this happened, False Diddy was made. Falco then flies down in an Arwing. Falco swoops out of the airwing and destroys the Dark Cannon. Bowser leaves and the group looks back at the False Diddy who they find out is gathering more Shadow Bugs. False Diddy then grows to an enormous size. Fox touches Diddy's trophy thus bringing him back to life and the three defeat False Diddy. Once defeated False Diddy's trophy disintegrates into the original Shadow Bugs.

False Power Suit
When Pikachu and Zero Suit Samus were fighting their way through the Research Facility, Samus located her old power suit. While retrieving it, two Dark versions of Samus attacked the duo. After defeating them, Samus donned her Power Suit and continued, annhialating the R.O.Bs sent to attack her.

False Peach
After the Shadow Bugs cover Peach's trophy, they turn Peach into False Peach, if the player saved Peach in the begining of the game when fighting Petey Piranha. While Mario and Pit are running, False Peach attempts on shooting them. However, right before she is able to, Link destroys the Dark Cannon. False Peach angrily looks at Link and his partner Yoshi and they fight. Link and Yoshi win the battle, and after that, the False Peach trophy turns back into the normal Peach trophy. Mario saw this however and thinking Link is the enemy because he attacked Peach, Mario tries to attack Link. Link quickly moves out of the way. Peach's trophy is later taken away by King Dedede.

Later on in the story, Peach and Zelda's trophies are taken aboard the Halberd locked up in cages. When Snake, Meta Knight and Lucario enter the room where their trophies are, Shadow Bugs come in and turn both Peach and Zelda into False Peach and False Zelda. The three battle and soon the two False Princesses are turned back.

False Zelda
It pretty much has the same role as False Peach, however she can only be seen in the story mode by saving Zelda from Petey Piranha. She tries to zap Link, and Yoshi instead of Peach zapping Mario and Pit. Also, Mario and Pit get to fight False Zelda instead of Link and Yoshi fighting False Peach. Like Peach, Zelda's trophy is taken on the Halberd and Snake, Meta Knight and Lucario also fight False Zelda as well as False Peach.

Beings made of Subspace
There are similar beings, called Subspace Clones, that must be defeated in order to fight Tabuu. One must fight a clone of each character in SSBB (excluding Wolf, Toon Link, Sonic, and Jigglypuff), along with a copy of each boss.

While fighting each, the stage changes. Subspace clones are somewhat weak like Polygons, Fighting Wire Frames, and Fighting Alloy Team, but they can fight hard depending on the difficulty of the game.

When Kirby uses Inhale on them, they will take damage, but not be inhaled into his mouth, and therefore cannot be swallowed and copied.

If you look closely, you can see that the being is a little larger than the original character. Another fact is that each being is actually recolored to make it more ominous looking. This can be seen if you zoom in on the back of the Wario Being.

Many have managed to hack into the game to have the ability to play as the "dark" Subspace beings in a normal brawl, often for "evil twin" battles. A example video can be seen here.
