Power Star

Power Star is a work of fiction set in the Mushroom Kingdom by Newground's author Daniel Sun. The plot unveils upon Mario's encounter with boo ghosts that possess him and make him into a demonic state controlled by some unknown dark power. Luigi in this case becomes the only one capable of defending the Mushroom Kingdom and does so. The battle becomes more and more furious during the fight scenes. As they continue to fight possessed toads appear and completely overrun the Mushroom Kingdom. Near the end, Luigi can't take the evergrowing power from the powerful dark force controlling Mario and he succumbs to its might as he is thrown aside and killed by the demonic power. The possessed Mario then runs up to Peach (aka Princess Toadstool) with a sword and pierces her and just laughs as he kills her. The battle is then over without a happy ending and the bleak aftermath ends up with Mario snapping out of his possession and pierces himself to save the Mushroom Kingdom from certain destruction.
