Almost every single world I could think of is now one, causing there to be tons of heroes, but also tons of villains. This was a series I wanted to do for a LONG time. Credit to Nintendo for Goombas, Koopas, Mario, Captain Toad, and Sega for Sonic and Tails. DISCLAIMER: This is not an official series by any of these companies. I am simply doing this for fun and because I want to.
