Castle Bleck

Castle Bleck is the setting of Chapter 8 in Super Paper Mario. Located in a realm of darkness, it is the home of Count Bleck.

In 8-1, Bowser and O'Chunks face off against each other. When Bowser wins, the ceiling begins to fall; however, O'Chunks holds it up because of his honor code. Bowser stays behind, even as the two keep telling one another to leave.

In 8-2, Mimi impersonates Merlon to tell Mario to hit a nearby ! Block. Even though the trap is obvious, the player must fall into it to continue. When they get out of the pit that they've fallen into, Mimi impersonates Merlee for the third time in the game. She then asks the player a series of questions about what they hate most reminiscent of the questions Kammy Koopa asked Peach in the original Paper Mario. After going through the hallways filled with the responses, Mimi taunts Peach, who demands a one-on-one fight with her. After Peach wins, the floor begins to collapse. Peach manages to hold onto the floor, and even prevents Mimi from falling to her doom.

In 8-3, the player encounters several rooms with mirrors as well as Dimentio clones. When they finally reach the end, Dimentio suggests that they team up so that all of them could control the Chaos Heart. Mario and Luigi, however, refuse. Dimentio then plans to attack both of them, but, when he insults Luigi's mustache, Luigi decides to defeat him on his own. When Dimentio is defeated, however, he presumably ends the game of both himself and Luigi.

Mario, now on his own, goes through the maze of the final area of Castle Bleck. He eventually reaches Count Bleck's chambers. After Tippi and Bleck argue, Bleck sends Nastasia away and begins to fight Mario. At first, Mario's attacks have no effect; however, it is revealed that Bowser, Peach, and Luigi all survived. The Pure Hearts disable Count Bleck's barrier, and, together, the four heroes defeat him.

Nastasia reappears, and Count Bleck tells the heroes to finish him off so that the Void will disappear. However, Tippi is reluctant to do so. They had only just been reunited, and she didn't want them to be ripped apart so soon. At that moment, a supposedly fatal blast of energy is sent toward Count Bleck, but Nastasia takes the blow instead. Dimentio appears, saying that the Chaos Heart would not disappear if he continued to control it. It is revealed that, after Luigi had defeated him, Dimentio had planted a mind-control seed in his subconscious. Dimentio then sends Tippi and Count Bleck to Dimension D, and continues with his plans. The Chaos Heart, Dimentio, and Luigi merge, creating a freakish creature reminiscent of both Brobot and Dimentio called Super Dimentio. Mario, Bowser, and Peach are unable to damage it.

Meanwhile, Tippi argues with Bleck that they have to do something to help Mario. Bleck, however, says that it's a pointless endeavor. They exchange a few more words before Mimi and O'Chunks appear, lending the count their support. The Pure Hearts, thought to have been wasted on Bleck, reappear, and Tippi takes them to Mario. Super Dimentio is able to be damaged now, and the final showdown commences.

Mario, Peach, and Bowser prevail, and Super Dimentio is defeated. However, he leaves behind one fragment of his power, so that the Void would still destroy all worlds even in his absence.

There was only one way to stop it: giving the Pure Hearts enough power through an act of true love. However, when that happened, everyone who would take part in it might die. Everyone goes through the final door, and they end up at the altar where Peach and Bowser got married at the start of the game. Bleck and Tippi go up to it, and proclaim their love for each other. In their supposed final moments, they are married, and the Chaos Heart is stopped.
