Plot
Peach has been kidnapped by her Anti self but nobody outside the kingdom knows that. Posing as the real Peach, Anti Peach has suddenly made everyone in the Mushroom Kingdom want to be equal and not different from each other in any way other than name or species. No one is being mind controlled, everyone is just too afraid to speak up against her because of the threats she’s given them, to not only potentially kill Peach but also them or declare war on them, so everyone rolls with it
Sonic and friends find themselves in the new Mushroom Kingdom through the portal and although the Mushroomians know what’s going on, no one will fess up because of what Anti Peach warmed them about. Will they follow everyone’s lead or will they help save the day?
Mario saw who cane through the portal and smiled “Hey guys! How ya doing?” He smiled, but he looked odd. He wasn’t wearing his traditional red cap, red suit and blue overalls, instead option for a white shirt and black overalls, with his hat being black and instead of the traditional red M in the center, it had a black equal sign (=) instead
