Sonic the Hedgehog vs. My Little Pony (STH vs. MLP for short): Parody of Mortal Kombat vs. DC Universe. Two worlds begin to collide and now, Sonic, his friends and foes must join forces against the combined might of My Little Pony characters, and deal with something called 'the Rage'. Which side will you choose? Sonic the Hedgehog? Or My Little Pony?
Walt Disney Hero Getter: A Disney version of "Super Sentai Hero Getter", an ending theme of Kaizoku Sentai Gokaiger. (If you guys have never heard of the Super Sentai series, then you had no idea about it. But if you insist, it's a Japanese version of the Power Rangers series.)
Pixar Hero Getter: Another version of "Super Sentai Hero Getter", but with Pixar movies.
Sonic the Hedgehog vs. My Little Pony: Extended Version: An extended version of "Sonic the Hedgehog vs. My Little Pony". Not giving spoilers until I finish the original one.
Disharmony: Equestrians and Mobians Among Us (cancelled and replaced): The Sonic the Hedgehog/My Little Pony version of Injustice: Gods Among Us. But, I cancelled it and replaced it for a Disney version, cause it gives me more interest.
Kingdom Kombat: Kingdom Hearts version of Mortal Kombat (2011). A severely weakened Eraqus is about to be killed by Xemnas, but casts a last-minute spell on his now-shattered magical amulet, directing it to contact his past self with the vague message "He must win".
Injustice: Disney version: Hercules murders Jafar during Aladdin's interrogation on him and quickly loses his moral compass. He establishes a new world order as the High Councillor. A war ensues between the forces of Hercules's Regime and those allied with Aladdin's Insurgency.
Sonic and Disney Heroes: Crossover between Disney and the Sonic Heroes game itself, but a little different. It doesn't take place after "Sonic Adventure 2". In Sonic's world, it takes place after "Sonic Generations" or "Sonic Lost World". And at the Disney World, it takes place after "Frozen" and before "Big Hero 6".
Mario, Sonic & Power Rangers at the Olympic Winter Games: The same story of "Mario & Sonic at the Olympic Winter Games", but with Power Rangers characters. Bowser & Dr. Eggman, along with some Power Rangers villains, melted all the snow in Vancouver and kidnapped all the Snow Spirits. Mario and Sonic were excited to compete in the Olympic Winter Games, but what they didn't expect is that the Power Rangers teams were there to compete too. (From Mighty Morphin to RPM)
