Bowser and Kurten put days of work into this power-up, when they really could've just used the world's only power-up combiner as a much easier method (well, I guess the travel there would take a bit.), but alas, the Darksi Cherry (pronounced dark-sye) was created, giving the user an identical clone, but the chance of the clone turning on you has been raised to 200% and better health, leading to the creation of Mr. L, and could potentionally give the evil Cherry Mario a chance to fully live. Nothing outside of Bowser's Castle is known about this power-up, but it's highly recommended to avoid it.
