Cut DLC Content

Before the termination of SuperBot Entertainment and the subsequent end of support for PlayStation All-Stars Battle Royale, various pieces of additional Downloadable Content were being worked on by the developers, primarily the ones at SuperBot. Following the aforementioned layoff of the SuperBot team, all DLC content they were working on was put on hold by Santa Monica, in order to provide more development resources for the Zeus and Isaac Clarke DLC fighters. While it was likely that Santa Monica had every intention of picking development back up for the remaining DLCs, the game's middling playerbase as well as the migration of players to Sony's next platform, the PlayStation 4 likely contributed to the developers pulling from the project, this causing the remaining content, four characters and one stage, to never see the light of day.

Characters
There have been a confirmed total of 4 characters in development before the game was abandoned, with several more in the planning stages. As confirmed by former employees of SuperBot Entertainment, Dart Feld (The Legend of Dragoon), Abe (Oddworld), Ryu Hayabusa (Ninja Gaiden) and Tombi/Tomba (Tombi!/Tomba!) were all in various stages of development.


 * Dart Feld was believed to be the furthest character in development due primarily to the fact that his model was revealed shortly before SuperBot's termination. Abe and Ryu are thought to have not been far behind, especially given that Ryu's name was leaked as part of the game's base roster before it even released. Tomba was confirmed to have also been in development, but what stage was never specified.

Considered
A number of characters were put in the planning stages, but for one reason or another were unable to make it into the development stage. Like the confirmed characters being in various stages of completion, these ones had various stages of confirmation. They are as follows:


 * Crash Bandicoot and Spyro the Dragon were planned for the game's base roster. Activision demanded a heavy sum of money for Crash's inclusion, causing the deal to fall through. Spyro was also dropped from consideration due to the Skylanders franchise pushing Spyro out of focus.


 * Chun-Li (Street Fighter) and Sub-Zero (Mortal Kombat) were initially believed to have been proper considerations with negotiations that failed to go through, however they were later revealed to simply be names on a white board, and no process had even begun to include them.


 * Lara Croft was in talks, but Crystal Dynamics requested that their then-upcoming Tomb Raider reboot be allowed to release before they made any deals for a crossover.


 * In an interview, the developers revealed that the NISA were interested in seeing one or more Disgaea characters in the game.


 * In a recent interview with a former developer by Matt McMuscles in his What Happened! episode, a Final Fantasy character (possibly Cloud Strife) was in talks with Square Enix, but it was dropped early on, most likely due to Dissidia Final Fantasy NT, released in 2015, two years after the second wave of DLC was released. Another reason why it was dropped was due to SuperBot being a small company, which lowers the chance of getting the character off the ground.


 * According to an interview, it was originally planned to include the classic Dante (Devil May Cry 1-4) and Old Snake (Metal Gear Solid 4), however, Capcom and Konami pushed for the reboot rendition of Dante from DmC: Devil May Cry and Raiden from Metal Gear Rising: Revengeance, respectively, as both games were relatively new at the time.

Stages

 * The only shown cut DLC stage is the Gravity Rush x Journey stage. This stage was being worked on ever since the start of the development of Kat, and it almost reached the end of its development before getting cut due to the end of the support to the game. Former SuperBot Employees would later go into detail on how the stage would have worked.


 * A Fat Princess Stage based on the Black Forest Stage of the game was in development. It was so early in development that a series to crossover with the stage hadn't been decided. The only known thing about the stage was that there were two towers on both sides of the stage.

Speculation

 * Other characters that were considered to be included in the roster are Blasto, Ellen (Folklore), Ico, Knack, Wander (Shadow of the Colossus), Croc and Rau Utu (The Mark of Kri).


 * It has long been believed that Shadow the Hedgehog was going to appear in the game. To the degree that he briefly became a meme and even sparked a release campaign like that of Dart's.


 * One of the characters that was also speculated to appear in the game would be Ezio Auditore, from the Assassin's Creed series.


 * It was speculated that originally Ty the Tasmanian Tiger was to appear in the game,
