Super Eviler Bowser's Shame is a shame starring Super Eviler Bowser. During this shame, the roles are reversed. The player plays as Bowser, while Mario is the antagonist.
The entire shame is a battle between Super Eviler Bowser and Mario. Super Eviler Bowser gets all sorts of cool powers, while Mario occasionally finds a Fire Flower and shoots fireballs. When the player wins the shame (usually in about one minute, due to how powerful Super Eviler Bowser is), Mario is unlocked as a playable character. He always gets the snot beaten out of him by Super Eviler Bowser when played, so it is not fun to play as him.
This shame was overall popular. Who doesn't like a shame where you play as an all powerful character, beating up weak characters?
