The Mean Emcee is a completely green, MC style boss Wario must beat in Wario World, at the end of the Mirror Mansion level. The Mean Emcee's arena is a medium-sized square arena with three huge cups and has reflections of Spritelings in the background. When Wario encounters the boss, the Emcee will be crouching down, hiding his face. When Wario approaches him, he will rise up, twirl his cane, and laugh.
The Mean Emcee has only two attacks; absorbing yellow energy and dashing towards Wario, and doing a jig in place, twirling his cane.
Once hit a few times, he will hide under one of three cups, which will mix each other up, finally coming to a stop. If an incorrect cup is chosen, either Puppet Magons, Ninja Crows or Magicians will emerge and attack. If the correct cup is chosen, nothing will come out. The cup must be punched once more to make the Mean Emcee tumble out of the cup. Wario can then execute a Piledriver, Wild Swing-Ding, or Power Throw to knock a skull off his health meter. After each round, the cups will increase their shuffle speed. After repeating five times, access is gained to Pecan Sands, the last level.
The Mean Emcee is the first of the three bosses of Sparkle Land. The others are Ironsider and Captain Skull.
- His appearance resembles The Mask due to having green skin and similar clothing.
