PlayStation X Nintendo: Super Smash Bros All-Stars

PlayStation X Nintendo: Super Smash Bros All-Stars is a hypothetical video game idea by LeeHatake93 that crosses over PlayStation All-Stars Battle Royale and Super Smash Bros for Wii U and 3DS.

Story
Polygon Man, after being defeated in All-Stars, manages to make his way to the World of Trophies and gains control of both Master Hand and Crazy Hand, becoming the new entity, Master Polygon. Wanting to exact his revenge on the All-Stars, he brings them over to the World of Trophies and begins merging the two realms. More info will be revealed later..

Gameplay
The game would utilize both the SSB and PSASBR engines, as the gameplay would be a blend of both styles, utilizing both damage-based gameplay and instant-kill Supers. Most of a character's basic combos are taken from the gameplay style of PlayStation All-Stars, although throwing mechanics and recovery moves (such as Link's Hookshot and Cole's Lightning Tether) are carried over in the style of Super Smash Bros. In addition, each character will only have two Super Moves: a Final Smash, and a Super Smash. A Final Smash works just as it does in the Super Smash Bros series, wherein the super will deal a large amount of damage, but will not kill. The Super Smash is taken as a combination of PlayStation All-Stars' Super Moves and the Final Smash in that it will be a move that kills opponents instantly, but is accessed through an item rather than a chargeable meter. A Final Smash is accessed via a Smash Ball, and a Super Smash is accessed via a new item known as an AP Orb, which is a Smash Ball infused with All-Star Power (AP).

Another unique feature is the introduction of hidden characters, which are individual characters with their own movesets and costumes, but share a slot with another character. The most common type of hidden character is a "clone" character, such as Pichu to PIkachu and Kessler to Cole MacGrath. These characters are either alternate versions of a character, or the same character with a different moveset. However, there are also "true" hidden characters who share a slot with another character, but are not the same character and may have entirely different gameplay. An example of this would be Lammy from UmJammer Lammy, who shares a slot with PaRappa, and Lucas from Earthbound, who shares a slot with Ness.

The roster so far is taken directly from PlayStation All-Stars and the entire Smash Bros series, with a few additions. The Nintendo roster is largely composed of first-party characters, with only two known third-party guests. The PlayStation side is also composed of a large amount of first-party characters, although there are a few guest characters as well. Both sides have a roster of 37 revealed characters and 12 hidden characters.

Characters
The characters are listed by series.

Stages
Nearly every stage from across the entire Super Smash Bros and PlayStation All-Stars series return, albeit with some changes. Not all stages feature the crossover mechanic seen in the PlayStation All-Stars series, in fact this feature is only present in new stages and those returning from Battle Royale. Instead, all previous Nintendo stages and those from the other PlayStation All-Stars installments will recieve a "final" variation. For Nintendo stages, this gives them a variation based on the series' Final Destination stage. For PlayStation stages, they will become polygonal and take on elements of the Rival and Boss Arena from Battle Royale. This option is not present in stages that feature the crossover mechanic.

Classic stages mark stages that return from previous entries in the Super Smash Bros series and PlayStation All-Stars Battle Royale. Retro stages are stages from old-school installments of PlayStation franchises. Returning stages refer to stages from recent installments or sequels (in the case of PlayStation All-Stars: Battle Stadium).
