This is not official, it's some weird stuff made up by me and my friends

Little Mac

Little Mac was a mediocre boxer from downtown Detroit who was trying his hardest to win it all, but kept getting defeated by Sonic. After constantly getting defeated, Little Mac turned to steroids to keep up, and he finally beat Sonic in a boxing tournament. The steroids changed his mental chemistry though, and he started terrorizing the Detroit suburbs, because Luigi and his gang controlled downtown. This rampage caught the eye of Jigglypuff, and Little Mac was kidnapped by King K. Rool.
