List of Super Smash Bros. for Nintendo 3DS / Wii U pre-release and unused content

This is a list of pre-release and unused content for the game Super Smash Bros. for Nintendo 3DS / Wii U.

Gameplay
On the original presentation pitch for the game, Sakurai originally intended to have four custom special moves for each character, though in the final game characters received only three versions of each move.

Smash Run in the Nintendo 3DS game was originally intended to include a co-op mode, but due to the Nintendo 3DS's processor not being able to handle it the idea was scrapped.

Characters
During early stages of development, Takamaru from The Mysterious Murasame Castle was originally considered as being a playable character, but it was decided against due to a lack of familiarity. Takamaru was, however, implemented as an Assist Trophy. Chrom, the protagonist of Fire Emblem: Awakening, was also considered to be in the game, as he was commonly requested by fans. However, Sakurai thought he'd play too similar to Marth or Ike. Robin was chosen instead due to being a more unique character. Chrom, however, appears in the game as part of Robin's Final Smash, Pair Up, as well as in the form of a paid downloadable costume for the Mii Swordfighter. Heihachi from Bandai Namco's Tekken series was also considered as being a playable character, but was decided against since his moves would have been too difficult to implement into Super Smash Bros.; Heihachi was, however, included in the form of a Mii Fighter costume available as downloadable content. According to design documents for the games, Alph was at one point considered for being a playable character, but was later made an alternate costume for Olimar.

Dr. Mario, Dark Pit, and Lucina were originally supposed to be alternate costumes for Mario, Pit, and Marth respectively, but late into development were instead implemented as separate playable characters after it was decided to give them unique characteristics to distinguish them from their original counterparts, and since the team figured it would be insensitive to fans of Dr. Mario in Super Smash Bros. Melee to make him an alternate costume.

Ice Climbers
According to Masahiro Sakurai on Famitsu, he was planning on adding the Ice Climbers for Super Smash Bros. for Nintendo 3DS / Wii U, but despite the characters running without problems on the Wii U version, the team had trouble getting the Ice Climbers working in the Nintendo 3DS version as their presence caused framerate issues.

Super Smash Bros. Direct
During the presentation, the HUD icons for both Diddy Kong and Lucario are taken from Super Smash Bros. Brawl, rather than having new ones based on their new artwork.

Trophies
Prior to the official Japanese release of the game, footage and images were leaked of a build closer to the final, including unlockable characters and Trophies. The build for the game in these screenshots showed 686 Trophies total. The actual release for the game, however, features 685. Analyzing the leak and the final version of the game, it was discovered that a trophy for Tharja, a character from Fire Emblem: Awakening, was removed, and is not present in the game's files. It's unknown why this trophy was removed, but the reason is probably because her outfit was too revealing for the E-10+ Rating.

In the Wii U version, the Trophy for Rayman originally had one eye partly closed. For the final game, both eyes are wide open.

Miscellaneous
In the Nintendo 3DS version, the Flying Men were originally to have full 3D models, though due to strain on the hardware they were replaced with models based on the 2D sprite.

Icons
In the E3 2014 trailer, during Multi-Man Mode the Mii icons were their faces. In the final version their icon is the weapon of the respective Mii Fighter.

Data for an icon representing the Rhythm Heaven series can be found in the game's files, meaning that a character or stage based on the series may have been planned at one point.

Sounds
Voice clips for Kirby using all three of Palutena's custom neutral special moves exist in the game, suggesting that at one point Kirby would have been able to copy whichever neutral special the opponent is using. However, Kirby can only copy her default neutral special, Autoreticle.

Stages
Alongside data for Ridley and Metal Face, two stage bosses who are faced on the Pyrosphere and Gaur Plain stages, respectively, is data for an unused "Virus" boss enemy. It is possible that a stage was to be included based upon Dr. Mario, and the Viruses from the series were to be hazards.
