Top 10 Ideas for a Super Mario and Sonic the Hedgehog Crossover

Mash together the Mushroom Kingdom and the Emerald Hill Zone and you get a crossover between two of the most iconic video game franchises in history, Super Mario and Sonic the Hedgehog. Whether you're picturing Sonic spin-dashing through Bowser's Castle or Mario leaping to gather Chaos Emeralds, there's a universe of crossover possibilities to explore.

From epic boss battles that put Eggman and Bowser against our heroes to adventurous levels featuring iconic locations from both universes, there's no shortage of mind-blowing concepts out there. Picture the platforms, the puzzles, the power-ups, and of course, the high-speed action that could come from blending these two worlds.

The Top Ten

  1. Mario & Luigi: The Sonic Adventure

  2. Mario & Sonic

    Plot: Bowser and Dr. Eggman combine their worlds into one. Both Bowser and Dr. Eggman plan on ruling the combined world together and defeating Mario and Sonic. Mario and Sonic must go through stages they once traversed before in their respective worlds, collect the Chaos Emeralds, and rescue their friends.

    The game includes levels from Super Mario Bros. (1985), Super Mario Bros. 2: The Lost Levels, Super Mario Bros. 3, Super Mario World, Sonic the Hedgehog (1991), Sonic CD, Sonic the Hedgehog 2, and Sonic 3 & Knuckles. This game is a classic platformer that has everything you love from the original Mario and Sonic games.

    I was thinking that Super Mario Bros. 2 (USA) should be in the game as well, but only as either a bonus stage or DLC.

  3. Mario & Sonic Kart

    If this happens, I hope there are some elements from Sonic R. Seriously, imagine what would happen if Mario Kart crossed over with Sonic R.

  4. Super Mario Galaxy X Sonic Colors

    Both games accurately describe my childhood, as well as that of a number of other 2000's kids!

    Do you want Super Mario Galaxy 3? Do you want Sonic Colors 2? Well, how about a Super Mario Galaxy/Sonic Colors crossover?

  5. Mario & Sonic at the NFL

  6. Mario & Sonic Heroes

    That would be cool, especially if the controls were polished.

    Sonic Heroes had these:

    1. Team Sonic (Sonic, Tails, and Knuckles)

    2. Team Rose (Amy, Cream, and Big the Cat)

    3. Team Chaotix (Espio, Vector, and Charmy)

    4. Team Dark (Shadow, Rouge, and E-123 Omega)

    For Mario, let's have these teams:

    1. Team Mario (Mario, Luigi, and Yoshi)

    2. Team Mushroom (Toad, Toadette, and Toadsworth)

    3. Team Princess (Peach, Daisy, and Rosalina)

    4. Team Kong (Donkey Kong, Diddy Kong, and Funky Kong)

  7. Mario & Sonic at Disney World

  8. Sonic & the Paper Adventure (Sonic the Hedgehog & Paper Mario Crossover)

    Ideally, it would follow in the footsteps of Super Paper Mario. I enjoyed the original two and Sticker Star (even though it was different in many incorrect ways), but Super Paper Mario just felt the most enjoyable to me.

    Remember the Sonic Storybook series? Sonic & the Secret Rings and Sonic & the Black Knight took place in storybooks. This one would be the third installment of the storybook series.

  9. Mario Party Shuffle (Mario Party X Sonic Shuffle)

  10. Sonic Unleashed 2: Powered Up

    During the day, Sonic is a hedgehog. During the night, he's a werewolf/hedgehog hybrid, a werehog. For Mario, he can use power-ups. That's why I had the subtitle "Powered Up."

    Mario POWER-UPS:

    1. Super Mushroom (Various Mario games)

    2. Super Star (Various Mario games)

    3. Phoenix Suit (This is a made-up Mario power-up.)

    4. Frog Suit (Super Mario Bros. 3 and Paper Mario: Sticker Star)

    5. Carrot (Super Mario Land 2: 6 Golden Coins)

    6. Blooper Suit (Made-up Mario power-up)

    7. Blue Shell (New Super Mario Bros.)

    8. Penguin Suit (New Super Mario Bros. Wii and U)

    9. Super Acorn (New Super Mario Bros. U)

    10. Super Bell (Super Mario 3D World)

    11. Polterpup Bone (Made-up Mario power-up)

    Nine out of 11 listed are animal power-ups. Three of the nine animal power-ups are made up and should totally be introduced.

    Luigi vs Tails

    Come on, people! If it came to Mario versus Sonic, Sonic would win before Mario could do anything. But a Luigi versus Tails game would be cool! (I only put this on the list because they are probably my two favorite characters ever!)

  12. ?

    Mario and Sonic Kingdom Battle

    13. The Contenders

  13. Mario vs Sonic

  14. Mario And Luigi Worlds Collide

  15. Mario and Sonic RPG

    While fighting Eggman and Bowser, Eggman uses the 7 emeralds, and Bowser uses the Crystal Stars, accidentally creating a parallel universe for each world. Then they talk and stuff. Popple wants revenge on Mario and Luigi for defeating him before. He finds Wario and Waluigi robbing a Toad, and Nack the Weasel hunting for emeralds. After talking to them, they agree to join. Some of the Koopas have been robotized by Eggman.

    The bosses with emeralds or crystal stars are:

    Mario: Koopa Bros, Crystal King, Boulder Geist, Shadow Mario, Fawful, X-nauts, Dark Star Core.

    Sonic: Egg Emperor, Earth Dragon, Mecha Sonic, Chaos, Egg Dragoon, Mecha Sonic 2.0, Dark Gaia.

    Other mini-bosses are scattered throughout the game. The final bosses are when Eggman creates the Death Egg Robot 3.0, and Bowser turns into Giga Bowser. People around the world cheer for them.

    But it turns out the power of the Emeralds and Crystal Stars combined has created a monster with the power of both. Mario and Sonic both turn into their super forms and defeat the monster. The ending is when they return to their worlds.
