World of Chaos

The World of Chaos is the name of one of the final bosses from Kingdom Hearts.

The World of Chaos is a giant, bio-genetic Heartless battleship that Ansem bonded himself to as his final form. Capturing Donald and Goofy, Sora was forced to fight Ansem on his own until he retracted into his Guardian. But after getting his friends out and destroying the Core, Ansem reawakened to fight the three off before they did enough damage to destroy the World of Chaos and forced Ansem to separate himself from it, leaving him mortally weakened as a result. During the battle with it Ansem wielded a large Double bladed Soul Eater pole arm. He could also shoot lasers of darkness, as well as the ability to throw Bit Snipers. His ultimate attack consists of blowing Sora away and connects by firing countless destructive lasers tracking Sora.

Room Core
The Room Core is the heart of the World of Chaos It is reached when you have been reunited with Donald Duck and Goofy after the fighting Ansem the first time around. There isn't really a strategy to this fight, all you really need to do is whack at the heart and block the lasers coming from the tenticles shooting lasers.
