The same storyline and gameplay as Injustice: Gods Among Us, only all the characters are replaced by characters that fit within the Smash Brothers universe.


In a desire to stop evil, Mario forms a league of heroes. Several years from that time his brother Luigi, driven insane by his time spent in haunted mansions, tricks Mario into killing his wife, Peach, and in the process destroying his beloved Mushroom Kingdom. Driven by grief, Mario creates a One World government, dictated by him. The only ones in his way of total control is Boshi and his group of Insurgents. In a last attempt to stop Mario, Boshi has to reach out to an alternate universe's League, and in the process stops the vary tragady that creates the events of his own world.


As stated above each character plays the same as the Injustice character they replace. There might be slight differances as hight and shape would be differant, but overall it would as close as possible.


The original roster would contain 24 characters, each a replacement of the original 24 characters of Injustice. DLC characters would be added.

The Roster includes.

Hero Side
  • Yoshi (Batman)
  • Mario (Superman)
  • Link (Wonder Woman)
  • Mr. Game and Watch (Green Lantern)
  • Fox (Nightwing)
  • Pit (Green Arrow)
  • Kirby (Aquaman)
  • Pokemon Trainer/Pikachu (Shazam)

Like the characters each stage is a replacement of a stage in Injustice and would play close to the same. There are 15 stages featured:

  • Mushroom Kingdom Underground (Batcave)
  • Dr. Wily's Lab (Insurgency)
  • Summit (Fortress of Solitude)
  • New Pork City (Gotham City)
  • F-Zero (Metropolis)
  • Great Fox (Ferris Aircraft)
  • Hyrule (Themyscira)
  • Mt. Dedede (Stryker's Island)
  • Space Colony Ark (Watchtower)
  • Pokemon Center (Arkham Asylum)
  • Peach's Castle (Hall of Justice
  • Old Chateau (Wayne Manor)
  • Bowser's Castle (Joker's Asylum)
  • Water Temple (Atlantis)
  • Luigi's Mansion (Wayne Manor Night)

(I will add character and stage pages in the near future. As well as possibly more information on this page. If you have an idea for a DLC character that I haven't done yet let me know. I have some rules about what characters I actually add, such as no more than 4 from a single series, so at this point Mario and Legend of Zelda can no longer get more characters added to the Roster)
