List of Super Smash Bros. Brawl pre-release and unused content

Theses are beta elements from Super Smash Bros. Brawl.

Beta Elements
Some of the game world icons were initially the same as in the previous two games, but they were revised as time went on (Mario's Mushroom icon was refined and given spots, the Poké Ball icon has the top half colored in to properly represent how it is usually red, etc.). Also, the description for the My Music options originally said, "Adjust how often a song will appear on this stage." It has since been revised in a general tone to say, "Adjust how often songs appear on stages." Solid Snake was also meant to be more muscular, and was to have a gray suit rather than blue. The original Snake was less modernized and his down smash was going to be a more realistic bomb. Wario Bike, Drill Rush, Trophy Base, Summit, Halberd, Rainbow Cruise, and "The Flowers That Bloom in the Echoes" were originally called Wario Chopper, Triple Dash, Trophy Stand, The Summit, Battle Ship Halberd, Rainbow Ride, and, "Flowers Bloom on the notes" respectively. It's unknown why they changed these names, however, they likely changed Rainbow Ride because it was a Melee stage, in which it was misnamed Rainbow Cruise (although it remains Rainbow Ride in the PAL regions, mostly because it was called Rainbow Ride on the PAL version of Melee). Lastly, there were scenes taking place before the events of the Subspace Emissary where the Subspace Army takes over the Halberd and King Dedede unintentionally stalls Meta Knight from preventing it from happening. Masahiro Sakurai confirmed that he decided to cut this out and an update was made to confirm this together with how various events and characters in the Subspace Emissary comes together. One mistake the developers made was in the trailer, on the Halberd stage. As you watch the characters fight, Kirby uses his side special (Hammer Cartwheel) move from SSBM, while in SSBB, he uses his Hammer Spin. His move may have been tweaked after the trailer was released.

Here's a list of the songs that were removed from the final game:
 * Because I Love You- Earthbound
 * Eight Melodies- Mother
 * MGS2 Main Theme- Metal Gear Solid 2: Sons of Liberty
 * Beware the Forest’s Mushrooms- Super Mario RPG: Legend of the Seven Stars
 * Hippie Battle Theme- Mother
 * You Can Do Anything- Sonic CD (JP)
 * The Loner, Falco Lombardi- Star Fox Command
 * Ballad of the Windfish- The Legend of Zelda: Link’s Awakening
 * Yoshi’s Cookie Type A- Yoshi’s Cookie
 * Boss Battle Theme- Mario & Luigi: Partners in Time
 * The Chosen Ones- Fire Emblem
 * Smiles and Tears- Mother

Also, unused files for Dixie Kong, Toon Zelda, Toon Sheik, and "Pra_Mai" (speculated to be Plusle & Minun of Pokémon fame) were found as scrapped newcomers. There were also files for Dr. Mario, Mewtwo, and Roy, possibly meaning that they were planned to be brought back at one time, or that their data was imported for some reason. A scrapped Assist Trophy for Ridley was also found. It was most likely scrapped in favor of a Boss version of Ridley. The full list of files can be seen here: Donkey Kong and Diddy Kong had a early trophy before they had the one in the game.
 * There are a few things in the 06 E3 trailer that is different from the final version.

When the characters at the beginning turn into their Brawl artwork Kirby has barely no physical difference. Mario grabbed the Smash Ball rather then attacking it, this may have been an early idea but Nintendo probably rendered it as "too easy". Samus's final smash was executed quickly, this may of been an early idea of how the final smash would look or it was made like this to fit in the trailer. When Samus turned into Zero Suit Samus she made her paralyzer turn into some sort of plasma sword, (Which looks a lot like Plasma whip or Plasma wire.) this might of been an early idea of how she attacks.

A video called "Game Intro" is found in the game itself, judging from its name this could of been an early version of the Super Smash Bros. Brawl intro, it included different clips of the Subspace Emissary, and it also had the Super Smash Bros. Brawl theme song menu version, rather then the version with the opera singers in the background. There was also a clip of Kirby fighting on the Halberd while executing his early Side-B, as opposed to his new horizontal Hammer.

Also another video called "Sonic Joins The Brawl" depicts Mario and Sonic fighting in Battlefield, but Sonic did a move which was charged up and held like Spin Dash, but when it was released it didn't do a short hop, but rather it rolled along the ground like Spin Charge, this may of been an early version of how Spin Dash worked.

The Triforce Slash was shown to have a different animation. Also, Link was meant to have longer hair.
