Super Dimentio

Super Dimentio is the monstrous combination of Dimentio, the Chaos Heart and Luigi, fought as the final boss of Super Paper Mario. Luigi was picked by Dimentio to serve him in universal destruction for that the Dark Prognosticus states that "The man in green shall use the Chaos Heart's power to bring darkness to all," meaning that Luigi was the ideal host for its power.

Super Dimentio was born shortly after Dimentio assumed control of the Chaos Heart, which he obtained following the defeat of Count Bleck. Super Dimentio harvested the power of the Chaos Heart, rendering him invincible to any of Mario's attacks and thus putting into motion the destruction of all worlds.

Meanwhile in Dimension D, where Dimentio had imprisoned Count Bleck, Tippi and Nastasia, Bleck, Tippi, and his minions expressed feelings of hope and love, restoring the Pure Hearts. The Pure Hearts were then used upon Super Dimentio to weaken the power of the Chaos Heart, nullifying his imperviousness. Super Dimentio was finally defeated in a magnificent explosion, releasing Luigi and the Chaos Heart from control and sending Dimentio in obliteration.
