The Null Void DP is a particularly perilous place for players. Fusions which had been thought to have disappeared when Fuse was first defeated have shown up in there in even more powerful forms. They are extremely dangerous to any who dare to enter. There are also broken sky-lands hovering around, as well as flying rocks that cluster around the floating lands, some serving as platforms to transport players from one to another, but others as dangerous obstacles to be avoided.
