Instead of just thinking of new characters to add in the game, I'd like to hear your ideas for modified versions of existing characters. With alternate versions, It's not as much work to add the characters, and they could also use the same music as the existing characters. Some examples are the Zelda 2 version of Link, or the Super Mario Bros 3 version of Mario. I'd like to hear if you have some other ideas. Maybe these alternate versions could be unlocked after you beat the game or something. Thanks.
